The company was incorporated on 5 October 2015 and lists its registered address as Minato Ward, Japan. 5 shareholders are on record for Riso Kagaku Kogyo 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 of Riso Kagaku Kogyo Co., Ltd.
Five shareholders are currently on record for Riso Kagaku Kogyo 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 33.4% — the largest recorded stake — followed by Vanguard Tax Managed Fund-Vanguard Developed Markets Index Fund at 19.2%; the remaining 3 shareholders shown hold 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.

Data availability
Those 21 subsidiaries span Japan, Thailand, United States, United Kingdom, Germany, China, and 7 more 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. Three of the 21 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
