Japan Post Bank Co., Ltd. (JP3946750001) closed at JPY 3,264 on the Tokyo Stock Exchange on September 18, 2026, down 0.67 percent from the previous close. The company carried a market capitalization of JPY 11.626 trillion, giving investors a precise valuation reference after Japanese markets remained closed for a public holiday on September 23, 2026.

Stock keeps a large valuation base

Market data published on September 23, 2026, identified Japan Post Bank under ticker 7182.T and classified it in the regional banking industry. The quoted market value of JPY 11.626 trillion places the bank among Japan's largest listed financial institutions by equity value.

The latest available quote also provides a quantified comparison: the shares fell 0.67 percent from the prior close to JPY 3,264 on September 18, 2026. That dated move is the relevant reference because the Tokyo market had no regular session on September 23, 2026, according to Saxo.

Quarterly earnings set the backdrop

The broader Japan Post group reported Q1 FY27 earnings of JPY 125.3 billion and revenue of JPY 2.99 trillion, with a profit margin of 4.20 percent, according to Yahoo Finance. The period label Q1 FY27 makes these figures the most recent reported operating reference in the available market data.

For Japan Post Bank, the key distinction is valuation scale versus fresh company-specific earnings detail. The bank's JPY 11.626 trillion market capitalization is more than 3.8 times the group's reported Q1 FY27 revenue of JPY 2.99 trillion, a cross-company comparison that should not be read as a valuation multiple because revenue and equity value measure different things.
