Nippon, Occupied Japan, U.S. Zone: what the mark on the bottom actually proves

By Matthew Partsch · Owl and Twig Vintage · September 15, 2026

Every dealer treats the word Occupied as the hardest date in the category. It was legally required for thirty-three months, not for the seven years of the occupation, and United States law never asked for the word at all. Germany ran the same play twice over, and the British invented the whole idea in 1887 as an insult. Here is the law behind these marks, the directives that ended them, and what each word is actually worth on the open market.

What United States law actually requires

The reason a country name on the bottom of a dish can date it at all is that the name is not decoration. It is compliance text, written to satisfy a statute, and statutes have dates.

The governing law today is Section 304 of the Tariff Act of 1930, enacted June 17, 1930 and codified at 19 U.S.C. 1304. Its opening sentence is worth reading once in full, because almost every dating rule in this category falls out of it:

Four requirements, and every one of them leaves a physical trace. Conspicuous is why the mark is on the foot rather than hidden under a glaze. Legible, indelible and permanent is why it is fired into the piece rather than written on in pencil. The English name of the country of origin is the clause that ended the word Nippon. And an ultimate purchaser in the United States tells you who the sentence was written for: not a collector eighty years later, but a person standing in a store deciding what to buy. The customs regulations restate the same requirement at 19 CFR 134.11.

The requirement did not appear all at once. It tightened across four decades:

Act	What it added	Why it matters to you
Tariff Act of 1890 signed October 1, 1890	The first general American requirement that imported articles be marked to show their country of origin. The trade universally dates the rule to 1891, from the marking section coming into force after the rest of the act.	This is the wall behind every dating guide you have ever read. An unmarked import is not necessarily pre-1891, but a marked one is very rarely earlier.
Act of 1913 Section IV, paragraph F	Required merchandise to be marked to indicate the country of origin, but provided no additional duty for failing to do it.	A rule with no penalty is a rule with uneven compliance. Expect gaps in this window.
Tariff Act of 1922 Section 304(a)	Required marking in legible English words in a conspicuous place, and added a duty for non-compliance.	The teeth arrive. The phrase legible English words is the one that had already done for Nippon the year before.
Tariff Act of 1930 Section 304, 46 Stat. 687	The English name of the country of origin, indicated to an ultimate purchaser, marked indelibly and permanently.	Still the law. Everything you turn over at an estate sale after 1930 was marked to satisfy this sentence.

We should be plain about one gap. We could not retrieve the text of Section 6 of the 1890 act itself from a primary source on this pass; the act was signed October 1, 1890 and its tariff schedules took effect October 6, 1890, while the 1891 date attached to the marking rule comes from the antiques trade rather than from a statute we have read. Treat 1891 as a reliable working convention with a citation we still owe you.

Reading the compliance text before you admire the object is the same habit that runs through reading a copyright page and reading the base of a Haeger pot. The boring part is the dated part.

The four marks, and the years each covers

Japanese export marks to the United States fall into four eras. The windows below are what each mark supports, which is not the same as what each mark is usually claimed to prove.

Mark	Window	What it actually proves
Nippon	circa 1891 to 1921	Export to the United States under the English-words rule, using Japan's own name for itself. Ends when a 1921 customs ruling held that Nippon no longer satisfied the requirement and that Japan was needed instead. This is the only one of these marks with a substantial counterfeit problem.
Japan or Made in Japan	1921 to 1941	Export between the Nippon ruling and the closing of Pacific trade. An enormous and largely undifferentiated category; the mark alone tells you very little beyond the bracket.
Made in Occupied Japan or Occupied Japan	1947 to 1952, mandatory only from February 1947 to December 1949	Manufacture for export under the Supreme Commander for the Allied Powers. A genuinely tight bracket, and tighter than most sellers realize. It is also not evidence of scarcity.
Japan or Made in Japan again	1952 onward	Nothing beyond post-war. The mark runs to the present day, so it dates a piece only in combination with form, glaze, importer name and construction.

One date inside that third row is worth having, because it narrows the window from the commercial end rather than the legal one. Ordinary private trade between Japanese suppliers and foreign firms had been suspended; a State Department telegram of August 25, 1947 advised posts that the occupation authorities were prepared to authorize export and import transactions between Japanese agencies and private foreign business firms following September 1, 1947. Before that autumn, the consumer goods that fill this category were not moving through normal private channels at all.

Why Occupied Japan lasted thirty-three months

The instruction that created the mark is a document with a number and a date. SCAP issued its directives to the Japanese government as SCAPINs, and SCAPIN 1535, dated February 20, 1947, is titled Marking of export articles. Its operative sentence:

Two things in that sentence deserve attention. The first is every article. There is a claim in wide circulation that only half of exported goods had to carry the mark, which would neatly explain the salt and pepper pairs that turn up with one shaker marked Occupied Japan and the other marked only Japan. We could not source that claim to any directive, and the directive we can read says every article. The pairs have a simpler explanation, which is the second date.

The second thing is after 15 days of receipt, which puts the first compliant goods in early March 1947 rather than on the date of the order.

The requirement was then rescinded. SCAPIN 2061, dated December 5, 1949, withdrew the mandate and left manufacturers free to use Made in Occupied Japan, Made in Japan or simply Japan. Many kept using the longer form well into 1951 out of habit and inventory; camera makers in particular are documented doing so. But from December 1949 the word was optional, and a mixed pair is what an optional rule looks like on a shelf.

Set the arithmetic out and the conventional wisdom falls apart:

Period	Span	Length
The Allied occupation of Japan	September 1945 to April 28, 1952	about 80 months
Occupied Japan marking mandatory	February 20, 1947 to December 5, 1949	about 33 months
Private export trade open to foreign firms	from September 1, 1947	about 27 months of the mandate

So the mark is both better and worse evidence than it is usually treated as. Better, because a piece marked Occupied Japan is pinned to a bracket a fraction of the length of the occupation, and for most consumer goods to a window of roughly two and a quarter years. Worse, because the absence of the mark proves nothing at all. A figurine marked only Japan may have left Nagoya in 1950 with the full blessing of the occupation authority.

How to tell a real mark from a faked one

Almost nobody fakes an Occupied Japan mark, for the same reason nobody counterfeits a dollar coin. The economics do not work. Nippon is a different matter, and the Nippon Collectors Club maintains a standing reproduction alert on exactly which backstamps are copied.

The faked marks are the Morimura Brothers family: the Maple Leaf (roughly 1891 to 1911, in green, blue or red), the M-in-Wreath (roughly 1911 to 1921, in several colors), and the RC and Rising Sun marks. The club notes that early fakes were loosely copied but that later ones came close enough to the genuine M-in-Wreath to confuse experienced collectors, which is a useful admission: the mark by itself has stopped being decisive.

So judge the piece, not the stamp:

• Hold it to a light. Genuine Nippon porcelain is described by the collectors' club as a bright white that is thin, light, translucent and well balanced. A heavy, chalky, opaque body under a good-looking backstamp is the commonest tell there is.
• Look at the gold, not the gilding pattern. Genuine gold reads lustrous with a warm patina. Fakes are characterized as brassy and almost harsh. This is a judgement you can make in a second once you have handled one of each.
• Count the techniques. Real pieces stack decorative processes to build dimension. Reproductions generally stop at painting the design. Moriage, coralene and tapestry work do not appear on the counterfeits.
• Check the glaze. On genuine work it should read as evenly applied, light, smooth and essentially undetectable as a separate layer.
• Ask where the mark sits relative to the glaze. A fired underglaze mark lies beneath the glassy surface and cannot be abraded off. A mark added later sits on top, catches a fingernail, and wears in a pattern that does not match the wear on the foot rim around it.
• Compare wear to wear. A base that has been sliding across shelves for a century has scuffing. A pristine, crisply printed mark inside a scuffed foot ring is a contradiction worth explaining before you pay.
• Read the mark as a sentence, not a picture. On an Occupied Japan or a U.S. Zone piece the word order, spacing and the presence or absence of Made in are all just ink. What you are checking is that the marking method suits the date: an ink stamp under glaze, an overglaze decal, an impressed mark, or a paper or foil label, all of which were lawful under the statute's allowance of any reasonable method of marking.

The look-alikes, and the honest near-misses

As with Keeler and Maddux flamingos, most of what gets called a fake here is not a fake. It is a different legitimate thing that a seller has misread.

What you are looking at	How it fools you	The tell
An importer's name, read as an origin mark	Lefton, Ardalt, Napco, Enesco and a dozen others are stamped prominently and look official.	These are American importers and distributors, not foreign factories and not countries. The origin mark is a separate element and is often a paper label that is long gone. Our Lefton guide works through one of these houses in detail.
A missing paper or foil label	An unmarked base reads as suspicious, or as pre-1891.	The statute permits any reasonable method of marking, including labels. Vast quantities of mid-century export ware were marked with paper or foil only. A shadow, a glue haze or a ring of cleaner residue on the base is the evidence.
Modern goods marked Nippon	The word is simply Japanese for Japan and appears on contemporary products and packaging.	Context, body and construction. Nippon on a piece of new souvenir ware is a word in a language, not a backstamp from 1905.
Occupied Japan on a post-1949 piece	It looks like a straightforward 1947 date.	Nothing on the piece will settle it. After December 5, 1949 the mark was voluntary, so the honest bracket is 1947 to 1952 rather than 1947 to 1949.
A region read as a country	Bavaria, Silesia and Thuringia are stamped large and look like origin marks all by themselves.	They are regions. The country word is the compliance element and is usually nearby in smaller type. Bavaria plus Germany plus U.S. Zone on one base is three separate pieces of information, and only the last one is a date.
Japanese tin and celluloid toys	They carry the same marks and the same era, but the collector market values maker and character far above the country mark.	The lithographed maker's symbol usually matters more than the word Japan. We took one of these apart in the Mechanical Martin.
A dated-looking base that is not a date	Copyright years, mold numbers and pattern numbers all read as manufacture dates.	Same trap we documented on ceramic Christmas trees. The country mark is the dated element on these pieces. The numbers beside it usually are not.

Germany ran the same system, twice

Everything above has a German twin, and the German version is older, stranger, and in market terms considerably scarcer. If you handle European ceramics, tin toys or cameras at all, these are the marks doing the same job.

Start with the part almost nobody knows. The American marking law of 1890 was not the first. The British Merchandise Marks Act received royal assent on August 23, 1887, three years earlier, and it was aimed squarely at Germany. British manufacturers were losing ground to German industry and wanted foreign goods labeled so that patriotic shoppers could avoid them. The act also closed the indirect routes, barring English wording, royal arms and English place names on foreign goods. A contemporary commentary on the act, published in 1888, states the requirement in almost the form we still use: a definite statement should be added, such as manufactured in Germany, to indicate the origin of the goods.

After 1945 Germany then ran the whole sequence a second time, and this one is the direct parallel to Japan:

Mark	Window	What to know
Germany or Made in Germany	1887 in Britain, circa 1891 in the United States, through 1945	The original, and the one the British act created. Region names such as Bavaria often appear alongside it.
Made in Germany U.S. Zone, US-Zone Germany, and the British and French zone equivalents	about 1945 to 1949	The German equivalent of Occupied Japan, and the short, scarce one. Specialist mark references date the U.S. Zone stamp on named factories to 1945 to 1949; a toy reference stretches it to 1952, so treat the edges as soft.
Western Germany, then West Germany, then W.-Germany	1949 to 1990	The Federal Republic. The sequence itself is a rough decade indicator: the longer, more formal wording is the earlier one.
Eastern Germany, then East Germany, then German Democratic Republic, then GDR	1949 to 1990	The same compression on the other side of the line. GDR and DDR pieces are a separate and still under-collected market.
Germany or Made in Germany again	from October 3, 1990	Reunification. The mark reverts, and stops dating anything on its own.

Two cautions on that table, stated honestly, because they are the two places a confident seller will get it wrong.

We could not find the governing order for the zone marks. For Japan there is a numbered directive with a date and a quotable sentence. For Germany there is a well-attested date range in the specialist mark literature and nothing we could locate in the military government record that actually required it. Treat 1945 to 1949 as reference practice rather than as statute, and notice that the toy collectors run the range four years longer than the porcelain collectors do.

Plain Germany never went away. The standard marks reference notes that many manufacturers simply continued to use the generic Made in Germany right through the 1949 to 1990 period regardless of where the factory stood. So the same asymmetry holds as with Japan, and it is the single most useful thing on this page: West Germany proves the window, but plain Germany does not exclude it. A piece marked only Germany can be 1900, 1935, 1962 or 2005, and the mark alone will not tell you which.

There is one more German mark worth knowing precisely because it is not rare at all. W. Germany on the base of a chunky, thickly glazed vase is not a curiosity, it is the category's name. West German art pottery, which the market has been calling Fat Lava for twenty years now, is identified first by that mark and second by the impressed three or four digit shape number and the height in centimeters beside it. Scheurich, Bay, Carstens, Ruscha and Ubelacker are the names, and the mark on the base is doing real work: a West Germany stamp puts the piece firmly inside 1949 to 1990, which is exactly the window the style occupies.

What these marks actually sell for

The same caution applies here that applied to the Princess phone. For these categories there is no realized-price record we can read and quote. One auction aggregator reports more than nine thousand Nippon price results, but the realized figures sit behind a subscription wall. Everything below is an asking price observed in September 2026, and should be read as what sellers hope for rather than what buyers paid.

Mark and category	Live listings	Asking range
Occupied Japan figurines, general marketplace category	19,076	$8 to $40
Occupied Japan bisque colonial couple, 10.5 inches	—	$39.99
Occupied Japan porcelain figure, small single piece	—	$9 to $12
Nippon moriage, general marketplace category	3,670	$12 to $479.99
Nippon moriage landscape vase, 12 inches	—	$323.89
Nippon moriage whiskey jug	—	$395
Hand painted Nippon vases at dealer level	14 offered	$125 to $1,450, averaging about $555
Made in Germany U.S. Zone, every category	602	$2 to $305
U.S. Zone tin wind-up toy, unnamed maker	—	$8 to $13
Schuco Combinato 4003 wind-up, U.S. Zone, with key	—	$155
Steinheil Munchen viewfinder, marked Germany US-Zone	—	$225
Tin wind-up elephant elevator, U.S. Zone	—	$305

Read the first row and the eighth against each other, because that comparison is the practical content of this entire guide. The mark with the dramatic wartime name is sitting in nineteen thousand listings at single-digit and low double-digit prices. The German equivalent, covering the same years and the same historical situation, exists in about three percent of that quantity. And the mark that is merely the old spelling of Japan's name carries a premium of one to two orders of magnitude at the top end, and is the one being counterfeited.

Within any of these, the price is not in the word. It is in the object: figural quality, size, complete pairs, a named maker, unusual forms, intact original labels, working mechanisms, and above all condition. A ten-inch bisque group is worth forty dollars because it is a ten-inch bisque group, not because of the stamp.

How to describe one in a listing

This is where the research pays for itself, because the difference between a defensible listing and a return request is usually one sentence of overclaiming.

• Transcribe the mark, do not summarize it. Write what is physically there, in quotation marks: marked Made in Occupied Japan, or marked Made in Germany U.S. Zone. A buyer searching that exact string will find you, and you have not characterized anything.
• Give the bracket the mark supports. For Occupied Japan that is circa 1947 to 1952. For U.S. Zone, circa 1945 to 1949. For West Germany, 1949 to 1990, which is a forty-year window and should be described as one.
• Do not write during WWII. Both of these marks postdate the war. It is wrong, and it reads badly.
• Say marked, not made by. An importer stamp tells you who brought it in, not who threw or molded it. A region stamp tells you even less.
• Photograph the base square and in daylight, large enough that a buyer can read the mark without asking. Half the questions in this category are a photograph the seller did not take.
• Do not call Occupied Japan rare. Nineteen thousand live listings is the counter-argument. U.S. Zone, at 602, you may reasonably call uncommon.
• Mention the label shadow if there is one. Evidence of a lost foil label is genuinely useful information and costs you nothing to state.
• Price the object, not the stamp. Then pack it as if it were worth what you would like it to be, which is a separate skill entirely.

What to check before you buy

• Turn it over first, before you look at the front. The front is why you picked it up; the back is why you should pay.
• Read the mark aloud, exactly as written, and note whether Made in is present.
• Separate the three elements: region, country, and importer or factory. Only the country word is a date.
• Decide which era the wording puts it in, and hold yourself to that bracket.
• Feel whether the mark is under the glaze or on top of it.
• Check the foot rim for wear, and ask whether the mark's condition agrees with it.
• Look for the ghost of a paper or foil label; a shadow is information.
• On anything claiming Nippon, hold it to a light and judge the body before you judge the backstamp.
• On anything claiming Nippon, look at the gold for warmth against brassiness.
• On West German pottery, read the impressed shape number and height next to the mark; they identify the form.
• Price the object. The stamp is a date, not a value.

The word that sounds rare

There is a particular pleasure in turning over a small painted figure at a church sale and finding the word Occupied on the bottom. It reads like a document. It sounds like history got into the clay, and in a narrow sense it did: somebody in Tokyo wrote an order in February 1947 requiring that every article leaving the country carry those words in legible English, and a factory in Nagoya complied, and the evidence is in your hand seventy-nine years later for four dollars.

But the order was not written to make a collectible. It was written to make an origin unmistakable to an American shopper who might otherwise not have known where the figurine came from, at a moment when that mattered enormously to both governments. And the policy behind it was an export drive, which means the mark is a record of volume. The reason there are nineteen thousand of these for sale this afternoon is precisely the reason the mark exists at all.

The German story makes the same point from the other end, and makes it sharper. A British Parliament sat down in 1887 and legislated a phrase onto its rival's goods specifically to damage them, and the phrase became the rival's best advertisement. Sixty years later the Allies stamped U.S. Zone onto the bases of the same country's teapots, and that one really is scarce, and almost nobody is looking for it.

Meanwhile the word that sounds like nothing much, the one that is simply how Japan says Japan, brackets a thirty-year stretch of genuinely fine porcelain, commands the prices, and gets counterfeited. If you only remember one thing from this guide, remember that you probably have them backwards, and that everybody else at the sale has them backwards with you.

Turn it over. Read the sentence someone was legally required to put there. Then decide what the object is worth, which is a different question entirely, and always was.
