Ocean System Co., Ltd.
Ocean System Co., Ltd. is a Private limited company (Ltd.) registered in Japan under 2110001013962, 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 Sanjo City, Japan. 1 shareholder is on record for Ocean System 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 28 September 2026.

Shareholders of Ocean System Co., Ltd.
One shareholder is currently on record for Ocean System 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 International Sustainability Core 1 Portfolio, 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.
