Shareholders of Oriental Consultants Holdings Co., Ltd.
Four shareholders are currently on record for Oriental Consultants Holdings 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 Japanese Small Company Series, holding 66.3% — a majority holding — followed by DFA International Sustainability Core 1 Portfolio at 22.8%; the remaining 2 shareholders shown hold smaller stakes.
