Onanba Co., Ltd. is a Private limited company (Ltd.) registered in Japan under 6120001011879, 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. 3 shareholders are on record for Onanba 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

3

Three shareholders are currently on record for Onanba 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 Catholic Responsible Investments International Small-Cap Fd, holding 59.6% — a majority holding — followed by Dimensional ETF Tr-Dimensional Int'l Core Equity Market ETF at 3.3%; the remaining 1 shareholder shown holds smaller stakes.

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 Onanba Co., Ltd. currently on record is Tadatoshi Kijima; five officers are currently on record for Onanba Co., Ltd., filed with National Tax Agency — Corporate Number Publication Site.

The register reports 6 officers in total, including past appointments, though only the 5 most relevant records are shown here.

Management authority at Onanba 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

Onanba Co., Ltd. has no recorded parent company — it sits at the top of its own group structure, with 12 subsidiaries recorded beneath it across 7 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 12 subsidiaries span Japan, Malaysia, Vietnam, Indonesia, United States, China, and 1 more 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. Two of the 12 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
