Market capitalisation 28.39T JPY, converted at 159.554 JPY/USD (Federal Reserve H.10, 2026-08-28). No reliable trailing-twelve-month revenue figure found as a newly relisted company (listed 2024-12-18) -- only fragmentary quarterly guidance -- so revenue_estimate is left null rather than annualised from one quarter.
