What this is
The book cost of the unlisted stake Nintendo sold in the year to March 2026: about ¥1.16bn.
How it’s built
- Subtract the reported gain (¥32.7bn) from the sale proceeds (¥33.8bn), both from Nintendo’s annual securities report.
What we assumed
- Book cost reflects what Nintendo paid.Write-downs would only lower book value, so the original cost could be higher but not lower.
Sanity check
The research identifies the stake as Niantic; a ¥1.16bn cost fits a 2015 investment of about $10m.
