Japan's Eight Functional Regions: From Hokkaido to Kyushu

Japan is commonly divided into eight major regions (chihō), each with distinct geography, climate, economy, and culture. These are not administrative units but functional/identity regions used in business, media, and planning.

1. Hokkaido — Northern Frontier

• Northernmost main island; cool, humid; snowy winters
• Capital: Sapporo (1.9M)
• Industries: Agriculture (rice, dairy, wheat), fisheries, forestry, tourism (skiing, Sapporo Snow Festival, Shiretoko NP)

2. Tōhoku — Northern Honshu

• Six prefectures (Aomori, Iwate, Miyagi, Akita, Yamagata, Fukushima); cold, snowy
• Major city: Sendai (1.1M)
• Industries: Agriculture (rice, apples), fisheries, manufacturing (electronics, auto parts), tourism (onsen, matsuri, Towada-Hachimantai)
• 2011 Great East Japan Earthquake epicenter; recovery ongoing

3. Kantō — Greater Tokyo

• Seven prefectures + Tokyo Metropolis; warm, humid
• Tokyo (37M metro — world's largest), Yokohama, Saitama, Chiba
• Industries: Finance, HQs, tech, media, publishing, advanced manufacturing, services — Japan's economic engine

4. Chūbu — Central Honshu (Three Subregions)

• Tōkai (Pacific): Nagoya (2.3M metro), auto (Toyota), aerospace, ceramics
• Kōshin (Mountains): Nagano, Niigata — winter sports, fruit, hydro
• Hokuriku (Sea of Japan): Kanazawa, Toyama — crafts, seafood, Shinkansen

5. Kansai (Kinki) — Cultural Heart

• Seven prefectures; Osaka (19M metro #2), Kyoto, Kobe, Nara
• Industries: Manufacturing (electronics, pharma, machinery), commerce, tourism (temples, shrines, UNESCO sites), culture

6. Chūgoku — Western Honshu

• Five prefectures; Hiroshima, Okayama, Yamaguchi
• Industries: Shipbuilding, automotive (Mazda), chemicals, tourism (Miyajima, Hiroshima Peace Park), Seto Inland Sea

7. Shikoku — Smallest Main Island

• Four prefectures; warm, humid; pilgrimage route (88 temples)
• Industries: Agriculture (citrus, wheat), fisheries, paper, tourism (Iya Valley, Shimanami Kaido cycling)

8. Kyushu — Southern Gateway

• Seven prefectures + Okinawa; subtropical south
• Fukuoka (5.6M metro), Kitakyushu, Nagasaki, Kagoshima
• Industries: Agriculture, semiconductors (Sony, TSMC JV), automotive (Nissan, Toyota, Daihatsu), volcanos (Aso, Sakurajima), onsen (Beppu, Yufuin)

These regions shape Japanese identity, dialect, cuisine, and economic specialization—more so than prefectures alone.
