Senba Co., Ltd.
Senba Co., Ltd. is a Private limited company (Ltd.) registered in Japan under 4010501032297, 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 Minato Ward, Japan. 1 shareholder is on record for Senba 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
1
One shareholder is currently on record for Senba 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 Old Westbury Small & Mid Cap Strategies Fund, 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.

Officers
5
The Managing Officer Of Corporate Affairs, Finance, Accounting & Pr And Director of Senba Co., Ltd. currently on record is Hiroaki Akiyama; five officers are currently on record for Senba Co., Ltd., filed with National Tax Agency — Corporate Number Publication Site.
The register reports 11 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at Senba 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
Senba Co., Ltd. has no recorded parent company — it sits at the top of its own group structure, with 6 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 6 subsidiaries span Japan, Taiwan, China, Singapore, Vietnam 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 6 go a level deeper still, with its own further subsidiaries recorded beneath it — additional ownership layers this view doesn't expand.
