Nippon Seisen Co., Ltd.
Nippon Seisen Co., Ltd. is a Private limited company (Ltd.) registered in Japan under 2120001093269, 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 Chuo Ward, Osaka City, Japan. 5 shareholders are on record for Nippon Seisen 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
5
Five shareholders are currently on record for Nippon Seisen 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 INVESTMENT DIMENSIONS GROUP INC-DFA Intl Small Cap Value PORT., holding 49.9% — the largest recorded stake — followed by DFA International Small Cap Value Portfolio at 10.2%; the remaining 3 shareholders shown hold smaller stakes.
The register reports 12 shareholders in total, though only the top 5 by holding are shown in this view.
Because every 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
5
The President, Ceo & Representative Director of Nippon Seisen Co., Ltd. currently on record is Kazuhiro Toshimitsu; five officers are currently on record for Nippon Seisen Co., Ltd., filed with National Tax Agency — Corporate Number Publication Site.
Management authority at Nippon Seisen 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
Nippon Seisen Co., Ltd. sits 1 level below its ultimate parent, DAIDO STEEL CO., LTD., registered in Japan. 4 subsidiaries are recorded beneath it, across 3 jurisdictions. The full chain up to DAIDO STEEL CO., LTD. is derived by walking shareholder filings across jurisdictions; no link in it is independently corroborated by Nippon Seisen Co., Ltd.'s own shareholder record. 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 4 subsidiaries span Japan, China, Thailand 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.
