Mamiya Opi Co., Ltd.
Mamiya Opi Co., Ltd. is a Private limited company (Ltd.) registered in Japan under 7010701022392, and its current status with National Tax Agency — Corporate Number Publication Site is active. The company was incorporated on 5 October 2015 and lists its registered address as Hanno City, Japan. 1 shareholder is on record for Mamiya Opi Co., Ltd., and since every one of them is a company rather than an individual, this particular filing does not on its own establish an ultimate beneficial owner (UBO) — identifying one would mean tracing the ownership of each shareholding company in turn. This profile is sourced directly from National Tax Agency — Corporate Number Publication Site and was last updated on 1 October 2026.

Shareholders
1
One shareholder is currently on record for Mamiya Opi Co., Ltd., reflecting the kabunushi meibo (shareholder register) maintained under Articles 121-122 of the Companies Act rather than a public filing.
The largest of these is DFA Japanese Small Company Series, holding 100% — a majority holding.
Because the shareholder shown is a company rather than an individual, the ownership chain continues above this level, and no beneficial owner can be established from this filing alone.

Officers
4
Four officers are currently on record for Mamiya Opi Co., Ltd., filed with National Tax Agency — Corporate Number Publication Site. Masao Sekiguchi serves as Ceo, President & Representative Director; Tsunehiro Higuchi serves as Md, Gm Of Administration Headquarters & Director; Fujiya Mizutani serves as Director; Takanori Shinoda serves as Md, Gm Of Technology Development & Director.
Management authority at Mamiya Opi Co., Ltd. sits with these individuals, not with shareholders, who are covered separately and hold ownership rather than control.
The source filing doesn't specify representation authority — whether officers can act individually or must sign jointly to bind the company — so that detail isn't available here.
Group Structure
Mamiya Opi Co., Ltd. has no recorded parent company — it sits at the top of its own group structure, with 7 subsidiaries recorded beneath it across 3 jurisdictions. Each of these downward relationships is derived rather than filed: resolved by matching entities across the registry network, not stated directly in a single document.
Those 7 subsidiaries span Japan, Thailand, United States jurisdictions, though this list should not be read as complete — subsidiaries only become visible here where shareholder data has actually been filed with a register, so holdings in jurisdictions without that filing simply won't appear.
