Interaction Co., Ltd.
Interaction Co., Ltd. is a Private limited company (Ltd.) registered in Japan under 8020001005906, 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 Kanazawa Ward, Yokohama City, Japan. 5 shareholders are on record for Interaction 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 Interaction 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 HC Capital Trust-The Institutional International Equity Portfolio, holding 15.9% — the largest recorded stake — followed by -Militia Long/Short Equity ETF at 5.5%; the remaining 3 shareholders shown hold smaller stakes.
The register reports 7 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 Interaction Co., Ltd., filed with National Tax Agency — Corporate Number Publication Site. Hideo Kiji serves as Founder & Chairman; Nobuo Kiji serves as President, Ceo & Representative Director; Hiroyuki Kaneki serves as Gm Of Corporate Planning & Director.
Management authority at Interaction 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
Interaction 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. Two of the 3 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
