The company was incorporated on 5 October 2015 and lists its registered address as Chiyoda Ward, Japan. 3 shareholders are on record for Ascentec 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
3
Three shareholders are currently on record for Ascentec 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 Brighthouse Fds Tr II-BH/Dimensional International Small Co Port, holding 46.7% — the largest recorded stake — followed by Dimensional ETF Tr-Dimensional World ex U.S. Core Equity 2 ETF at 30%; 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.

Management authority at Ascentec Co., Ltd. sits with these individuals, not with shareholders, who are covered separately and hold ownership rather than control.

Group Structure
Ascentec Co., Ltd. has no recorded parent company — it sits at the top of its own group structure, with 3 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 3 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.
