Analysis
Which of Japan's 1,741 municipalities has the largest total resident income from stocks and dividends? Toyo Keizai's ranking from municipal tax data—Nagoya fifth, Setagaya fourth—reveals a wealth map more concentrated than intuition suggests.
It reads as a side portrait of the savings-to-investment policy: NISA spread investing nationwide, but asset income compounds fastest where holdings were already large. Consumption power follows this map—premium retail, hospitality, and property demand overlap it closely—and so does the recurring political debate over financial income taxation, for which this is effectively a constituency map.
