Yamabiko Co., Ltd.
Yamabiko Co., Ltd. is a Private limited company (Ltd.) registered in Japan under 1013101005329, 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 Ome City, Japan. 5 shareholders are on record for Yamabiko 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 2 October 2026.

Shareholders
5
Five shareholders are currently on record for Yamabiko 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 Vanguard International Stock Index-Total Intl Stock Indx, holding 19.9% — the largest recorded stake — followed by DFA International Small Cap Value Portfolio at 17.6%; the remaining 3 shareholders shown hold smaller stakes.
The register reports 10 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.

The President, Ceo & Representative Director of Yamabiko Co., Ltd. currently on record is Hiroshi Kubo; five officers are currently on record for Yamabiko Co., Ltd., filed with National Tax Agency — Corporate Number Publication Site.
The register reports 15 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at Yamabiko 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
Yamabiko Co., Ltd. has no recorded parent company — it sits at the top of its own group structure, with 10 subsidiaries recorded beneath it across 5 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 10 subsidiaries span Japan, Vietnam, Belgium, Taiwan, 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. One of the 10 go a level deeper still, with its own further subsidiaries recorded beneath it — additional ownership layers this view doesn't expand.
