The company was incorporated on 5 October 2015 and lists its registered address as Miyagino Ward, Sendai City, Japan. 5 shareholders are on record for Yamaya 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.

Shareholders
5
Five shareholders are currently on record for Yamaya 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 Small Cap Value Portfolio, holding 51.4% — a majority holding — followed by DFA Japanese Small Company Series at 21%; 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.

Officers
3
Three officers are currently on record for Yamaya Co., Ltd., filed with National Tax Agency — Corporate Number Publication Site. Hiroya Sato serves as President, Ceo & Representative Director; Hidefusa Yamauchi serves as Founder & Director; Yuki Tawaraguchi serves as Executive Officer & Gm Of Accounting Department.
Management authority at Yamaya 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
Yamaya Co., Ltd. has no recorded parent company — it sits at the top of its own group structure, with 6 subsidiaries recorded beneath it across 1 jurisdiction. 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 6 subsidiaries span Japan jurisdiction, 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 6 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
