One formula, every club the site covers. See the whole board →
Who controls the club
The entity that holds control today, one per franchise; co-controllers and minority holders are listed, never summed.
How this is measured
Exactly one control entity is recorded per franchise, so a portfolio can never count a club twice. Co-controllers and minority holders are shown as published and carry no weight in any total.
The chip names the evidence. Sourced: a primary source is linked (league, club, filing or tier-one outlet). Cross-checked: matched against the ownership-change sweep. Contested: disputed or mid-sale. Rows are reviewed weekly.
Stakes are as published, often only “majority”, and are not pro-rated. A record of control is not a claim about anyone’s intent or conduct.
Who controls the clubSeibu Holdings (via Seibu Railway)
The team is owned by a subsidiary of Seibu Railway, which is in turn owned by the Tokyo-listed Seibu Holdings. The franchise has been in the Seibu group since its 1978 purchase and move to Tokorozawa.
