Made in Japan Stamp — What This Mark Means
A marking indicating the watch was fully assembled in Japan, not just the movement. This designation is particularly valued on Seiko, Citizen, and Orient watches for the domestic Japanese market.
What This Usually Means
"Made in Japan" signifies the entire watch was assembled in Japan, meeting specific criteria for Japanese content and assembly. For brands like Seiko, this often denotes models originally intended for the Japanese domestic market (JDM), which can include different dial variants, finishing quality, or features not available internationally.
Where to Find It
On the dial near the 6 o'clock position (similar to "Swiss Made" placement) and/or on the case back. On Seiko watches, JDM models often include a "J" suffix in the model number (e.g., SRPD55J1 vs SRPD55K1).

Common Variations
"MADE IN JAPAN," "JAPAN" on the dial, or a "J" suffix in the model reference. Some watches show "JAPAN A" or "JAPAN T" on the dial, where the letter indicates the luminous material used rather than assembly origin.
Common Misconceptions
A "J" suffix model isn't always significantly different from its "K" (international) counterpart. While some JDM models have exclusive features, many share identical specifications with a different model suffix. Also, the "JAPAN" dial text accompanied by a letter (A, T, P) refers to lume type, not assembly.
What to Do Next
If you're collecting or buying a JDM model, verify the model number suffix and dial markings match. Compare specifications with the international version to understand actual differences. JDM Seiko models can carry a modest premium in the collector market.
