🎎 Vintage Japanese Date Stamp — Showa-Era Rotary Seal | Japan Antique Roadshow
🎎 This fascinating piece is a vintage Japanese rotary date stamp, likely dating from the mid-Showa period. The stamp is constructed with a cast metal body, a rotating date mechanism, and a wood-and-rubber stamping surface featuring both kanji and a customizable Western-style date line. It’s an elegant blend of traditional Japanese business formality and industrial efficiency.
The kanji inscriptions read:
Top Section:
製造所 株式会社 大森製作所
(Manufacturer: Omori Seisakusho Co., Ltd.)
Center:
MT logo and adjustable metal type for stamping date or identifier
Bottom Section:
東京都豊島区巣鴨五丁目三十八番地
(Tokyo-to Toshima-ku Sugamo 5-chome 38-banchi)
The company was located in Tokyo’s historic Sugamo district, an area known for its old-world charm and strong ties to post-war commerce and community life. The overall construction suggests this was a professional office or administrative tool, used to apply dates to official forms or packaging.
The rotating date function is still operable, although somewhat stiff from age—making this stamp better suited for display or collection rather than practical use. A beautiful artifact of 20th-century Japanese industry and bureaucracy.
