Officers
5
The President & Representative Director of Medical Data Vision Co., Ltd. currently on record is Hiroyuki Iwasaki; five officers are currently on record for Medical Data Vision Co., Ltd., filed with National Tax Agency — Corporate Number Publication Site.
The register reports 10 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at Medical Data Vision 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
Medical Data Vision Co., Ltd. sits 1 level below its ultimate parent, NIPPON LIFE INSURANCE COMPANY, registered in Japan. 3 subsidiaries are recorded beneath it, across 1 jurisdiction. The full chain up to NIPPON LIFE INSURANCE COMPANY is derived by walking shareholder filings across jurisdictions; no link in it is independently corroborated by Medical Data Vision Co., Ltd.'s own shareholder record. 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.
