Why Honshu Is Japan's Most Populous Island

Honshu, Japan's largest island, hosts the majority of the population because it offers the best infrastructure, major cities (Tokyo, Osaka, Kyoto, Nagoya), and abundant natural resources (coal, copper, gold). The other islands—Hokkaido, Kyushu, Shikoku—are smaller, more mountainous, or have harsher climates, limiting large‑scale settlement.
