Kagawa is Japan's smallest prefecture by area but punches far above its weight. The headline draws are Ritsurin Garden in Takamatsu (Japan's most beautiful stroll garden per multiple rankings), the contemporary-art islands centred on Naoshima (contemporary art island), the 1,368-step pilgrimage up to Kotohiragu Shrine, the original-keep Marugame Castle, and the architectural Teshima Art Museum. Plus the inescapable Sanuki udon culture — Kagawa locals eat 3-4 bowls a week.

FAQ
How do I get to Kagawa from Tokyo or Osaka?
Domestic flight from Tokyo Haneda to Takamatsu Airport (75 min, then 45-min bus). From Osaka: JR Limited Express Marine Liner from Okayama (60 min, JR Pass valid). Direct shinkansen from Tokyo to Okayama (3.5 hours) then Marine Liner.
Is Naoshima worth a full day?
Yes — and overnight if possible. Day-trippers from Takamatsu (60-min ferry) can see the Benesse House Museum, Chichu Art Museum, and Yayoi Kusama pumpkins. Staying overnight on Naoshima or nearby Teshima opens up the Lee Ufan Museum and the Teshima Art Museum.
Is Konpira's 1,368 steps achievable?
Yes for fit travellers — 1-1.5 hours up, 30 min down, with rest stops. Older or mobility-impaired visitors can rent palanquins (¥6,800 one-way to step 365). Bring water; the cedar avenue is shaded.
What is Kagawa best known for?
Sanuki udon (chewy hand-cut wheat noodles eaten 3-4× a week locally), Naoshima art islands, Ritsurin Garden, the 1,368-step Konpira shrine, and Marugame Castle's tallest stone walls in Japan.
How many days do I need in Kagawa?
One day for Takamatsu and Ritsurin Garden. Two days adds a Naoshima art-island day. Three days lets you reach Marugame Castle and Kotohira's Konpira shrine.
What are Kagawa's hidden gems?
The Onigashima caves on Megijima (Momotaro folk-tale setting), the hilltop fishing village of Ogijima with its Spanish-style village, and the architectural Teshima Art Museum on the next island over from Naoshima.
What surrounds the headline spots?
Beyond the obvious draws, Honjima (Shiwaku Islands), Kan'onji, Mure reward travelers willing to step off the main route — local pace, fewer crowds, and a closer feel for the everyday rhythms of the region.
