Kagawa Prefecture: Japan’s Smallest Prefecture on Shikoku

Geography and characteristics

The prefecture combines a narrow coastal plain with low hills and numerous small islands in the Inland Sea. Its climate tends to be relatively mild compared with Japan's interior, supporting citrus orchards and maritime livelihoods. The shoreline, inland channels and island chains have shaped local culture, cuisine and transportation.

History and cultural life

Historically part of Sanuki Province, Kagawa developed as a regional maritime and agricultural center. Religious and cultural sites include important shrines and temples, and the area is crossed by sections of the traditional Shikoku pilgrimage route. A modern cultural highlight is the transformation of several islands into contemporary art destinations, attracting international visitors.

Economy and transport

The economy mixes agriculture, fisheries, light manufacturing and services. Local specialties such as Sanuki udon noodles and olive products from islands like Shodoshima are well known. Takamatsu functions as the transport hub: ferries and ports link the islands and Honshu, and bridge systems provide road and rail connections across the Seto Inland Sea.

Major attractions and examples

• Ritsurin Garden in Takamatsu — a historic landscape garden noted for its design and seasonal views.
• Naoshima, Teshima and other art islands — sites of contemporary museums and outdoor installations.
• Kotohira (Kotohiragu) — a famous shrine set on a wooded hillside popular with pilgrims and visitors.
• Sanuki udon culture — a regional culinary tradition with many specialist shops and local variations.

Notable distinctions

Kagawa is Japan's smallest prefecture by land area, yet it plays an outsized role in regional tourism and culinary identity. Its blend of traditional gardens, coastal scenery, pilgrimage heritage and contemporary art projects makes it a compact but varied destination within Shikoku.
