Kagawa Travel Guide for Japanese Learners
Japan's smallest prefecture — udon noodles and art islands.
Kagawa is synonymous with sanuki udon and with the contemporary-art islands of the Seto Inland Sea, anchored by Naoshima.
History & background
Kagawa (香川) is Japan's smallest prefecture, long famous for sanuki udon (讃岐うどん). Since 2010 the Setouchi Triennale has turned its Inland Sea islands, led by Naoshima (直島), into a global art destination.
What to see
- Naoshima and Teshima art islands
- Ritsurin Garden
- Kotohira-gū (Konpira) shrine
- Marugame Castle
Hidden gems
- Onomichi to Imabari Shimanami Kaido — A 70 km cycling route connecting islands with stunning sea views, local cafés, and quiet fishing villages.
- Denjūji Temple — A 8th-century temple in Zao with intricate wooden architecture and peaceful grounds, far less crowded than Kotohira.
- Shodoshima Island olive groves — Japan's oldest olive-growing region with small producer shops, Mediterranean-style terraces, and local olive-oil tastings.

What to eat
Sanuki udon — chewy, cheap, everywhere.
Getting there & when to go
Getting there: Takamatsu is ~50 min from Okayama by train over the Seto-Ōhashi bridge.
Best time: Spring/summer/autumn for the Setouchi Triennale art festival years.
When to go — season by season
Spring, summer, and autumn of triennale years are peak for the art islands. Udon is a year-round, all-day affair; Ritsurin Garden is lovely in every season.
Local culture
Sanuki udon culture runs deeper than tourist bowls: locals eat it standing at counter seats during lunch breaks, dipping thick noodles into warm dashi, then finishing the broth in seconds. The cheapest bowls cost ¥300–500, and quality depends on water source and kneading technique passed through generations of family shops.
Kagawa's fishing heritage shapes daily meals — dried seaweed, small sardines, and anchovies appear in nearly every set meal. The Seto Inland Sea's calm waters historically supported aquaculture, and you'll notice restaurants emphasizing 'local catch' on menus, reflecting pride in regional seafood traditions.
A suggested visit
Slurp self-serve udon for breakfast in Takamatsu (高松), stroll Ritsurin Garden (栗林公園), then ferry to Naoshima for its museums and the famous pumpkin sculptures.
Seasonal tip: Visit in late October or early November to avoid August's intense humidity and crowds, while catching autumn light perfect for photographing Naoshima's outdoor art installations and Ritsurin Garden's maples.
Local etiquette: At smaller udon shops without ordering systems, observe which counter seat other customers use, nod to the chef when entering, and eat quickly — you're in a working person's space, not a leisurely café.
Many Kagawa udon shops are self-serve and open early — a cheap, delicious breakfast.
