Kagawa Prefecture Guide: Udon, Art Islands & Shikoku's Gateway

Why Kagawa: Japan's Smallest Prefecture, Biggest Surprises

Kagawa Prefecture (香川県) is Japan's smallest prefecture by area — and one of its most rewarding for visitors who venture beyond the main tourist corridor. Located on the northern coast of Shikoku Island, facing the Seto Inland Sea, Kagawa has built an international reputation on three strengths: world-class contemporary art islands, Japan's finest udon noodles, and the most accessible gateway to Shikoku.

The numbers tell the story: over 500 udon restaurants in a prefecture you can drive across in an hour, three art islands that draw visitors from around the world, and a 55-minute train ride from the Sanyo Shinkansen at Okayama. For travelers exploring Japan beyond Tokyo and Kyoto, Kagawa offers a concentration of unique experiences in a compact area.

What Kagawa Offers at a Glance

Experience	Where	Time Needed	Best Season
Contemporary art islands	Naoshima, Teshima, Shodoshima	1 full day per island	Spring, autumn
Sanuki udon pilgrimage	Takamatsu + rural Kagawa	Half day to multi-day	Year-round
Ritsurin Garden	Takamatsu	2-3 hours	March-May, Nov
Kotohira Shrine (Konpira-san)	Kotohira town	Half day	Year-round
Seto Inland Sea scenery	Ferry crossings, island coasts	Ongoing	Spring-autumn
Setouchi Triennale art festival	Multiple islands	3-7 days	Every 3 years

Kagawa rewards both focused day trips and extended stays. A 2-day minimum covers Takamatsu and one island. Four days allows a more satisfying combination of city, islands, and countryside.

The Art Islands: Naoshima, Teshima, and Shodoshima

Kagawa's art islands have transformed former fishing villages into internationally recognized contemporary art destinations. All three are accessible by ferry from Takamatsu Port.

Naoshima: Contemporary Art on a Global Stage

Naoshima (直島) is the flagship — home to Benesse House Museum, the Chichu Art Museum (featuring Monet water lilies in a Tadao Ando-designed underground gallery), and the iconic yellow pumpkin sculpture by Yayoi Kusama. The island draws art enthusiasts from across the world and regularly appears on lists of must-visit cultural destinations.

The island is compact enough to explore by bicycle or bus in a full day, though overnight stays at Benesse House allow evening access to installations. For a comprehensive guide, see our Naoshima art island guide.

Teshima and Shodoshima: Art Meets Nature

Teshima (豊島) is smaller and quieter than Naoshima, anchored by the Teshima Art Museum — an architectural space that captures water, wind, and light rather than displaying conventional art. The experience is meditative and unlike any museum you have visited. For details, see our Teshima island art guide.

Shodoshima (小豆島) is the largest of the three — a genuine island with olive groves, soy sauce breweries, Angel Road (a sandbar that appears at low tide), and a Mediterranean atmosphere unusual in Japan. It works well as a combination nature and art destination. See our Shodoshima olive island guide.

The Setouchi Triennale (瀬戸内国際芸術祭), held every three years, adds temporary installations across multiple islands and significantly increases visitor numbers. If your visit coincides with the festival, book ferries and accommodation well in advance.

Sanuki Udon: Japan's Udon Capital

Kagawa is known as the Udon Prefecture (うどん県) — a nickname the local government has officially embraced. With over 500 udon restaurants, Sanuki udon (讃岐うどん) is not just a meal here but a cultural institution.

What makes Sanuki udon distinctive is the noodle itself: thicker, chewier, and more elastic than udon found elsewhere in Japan. The broth is typically clear and light, letting the noodle texture take center stage. At many shops, you order at a counter, choose your toppings (tempura, green onions, grated ginger), and eat standing or at simple tables — the experience is casual, fast, and remarkably cheap at ¥300-500 (~$2-3) per bowl.

The best udon shops in Kagawa are not in tourist areas — they are in nondescript buildings on rural roads, open only for a few hours in the morning and early afternoon. Many close by 2 PM. Udon-hopping (visiting multiple shops in a day) is a popular local activity. Ask at your hotel for current recommendations, as shop quality and hours shift frequently.

Takamatsu and Beyond: Mainland Kagawa

Ritsurin Garden and City Highlights

Takamatsu (高松) is Kagawa's capital and your base for island ferries, udon exploration, and city sightseeing. The city's signature attraction is Ritsurin Garden (栗林公園), an Edo-period landscape garden featuring ancient pines, serene ponds, koi fish, tea houses, and views of Mt. Shiun as borrowed scenery. It is consistently ranked among Japan's finest gardens.

Ritsurin Garden is walkable from Ritsurin Koen Station on the Kotoden Kotohira Line. For a comprehensive guide to what Takamatsu offers, see our Takamatsu city guide.

Kotohira Shrine: The Stairway Pilgrimage

Kotohira-gu Shrine (金刀比羅宮), commonly called Konpira-san, is one of Japan's most important Shinto shrines — and one of the most physically demanding to visit. The approach requires climbing 785 stone steps to the main hall (or 1,368 steps to the inner shrine). The stairway is lined with shops, rest stops, and historical buildings.

Kotohira is approximately 40-50 minutes from Takamatsu by Kotoden railway. The shrine grounds are free to enter. Allow half a day for the visit including the climb and return journey.

Planning Your Kagawa Trip

Getting to Kagawa from Tokyo and Osaka

The standard route to Kagawa:

Route	Method	Time	Notes
Osaka → Kagawa	Shinkansen to Okayama + JR Marine Liner	~2 hours total	Most practical
Tokyo → Kagawa	Shinkansen to Okayama + JR Marine Liner	~4-4.5 hours	JR Pass covers both
Tokyo → Takamatsu	Direct flight	~1.5 hours	Available from Haneda/Narita

The JR Marine Liner from Okayama crosses the Seto Ohashi Bridge to Takamatsu in approximately 55 minutes. No reservation needed for unreserved seats. The route is fully covered by the Japan Rail Pass.

How Many Days and When to Visit

Recommended stays:

• 2 days (minimum): Takamatsu + one island day trip (Naoshima recommended for first-timers)
• 3-4 days (ideal): Takamatsu, 2 island days, udon exploration, Ritsurin Garden
• 5+ days: Add Kotohira, second/third island, rural udon shops, relaxed pace

Best seasons:

• Spring (March-May): Cherry blossoms at Ritsurin Garden, comfortable weather for island-hopping
• Autumn (September-November): Mild temperatures, clear skies, foliage
• Summer (June-August): Hot and humid, but islands are open and ferries run frequently
• Winter (December-February): Some outdoor installations may close, reduced ferry schedules, but fewer crowds

During Setouchi Triennale years, spring, summer, and autumn sessions each add temporary art across the islands. Plan early — accommodation and ferries sell out.

Frequently Asked Questions

How many days should I spend in Kagawa?

Three to four days is ideal for a first visit. This covers Takamatsu city (Ritsurin Garden, udon), two island day trips (Naoshima plus either Teshima or Shodoshima), and time to explore the food scene. A focused 2-day visit works for Takamatsu and one island. Add a day for Kotohira Shrine if you enjoy shrine pilgrimages.

What is the best way to get to Kagawa from Tokyo or Osaka?

From Osaka, take the Shinkansen to Okayama (approximately 45 minutes), then the JR Marine Liner to Takamatsu (approximately 55 minutes) — about 2 hours total. From Tokyo, the Shinkansen to Okayama takes approximately 3 hours, plus the Marine Liner. Direct flights from Haneda to Takamatsu are also available (approximately 1.5 hours). The JR Pass covers the entire train route.

Can I visit Naoshima, Teshima, and Shodoshima in one trip?

Yes — all three are accessible by ferry from Takamatsu Port. Allow one full day per island for a meaningful visit. Multi-island trips work best over 3 or more days. During Setouchi Triennale years, book ferry tickets and accommodation in advance as the islands draw significantly higher visitor numbers.

When is the best season to visit Kagawa?

Spring (March-May) and autumn (September-November) offer the most comfortable weather for island-hopping, garden visits, and outdoor activities. Setouchi Triennale years add special art events across the islands but increase crowds and accommodation demand. Winter is quieter with potential ferry schedule reductions.

Do I need a car to explore Kagawa?

Not for Takamatsu and the art islands — ferries, trains, and buses cover the main destinations. On islands, electric bikes are a popular and practical option for getting around. A rental car is helpful for visiting Kotohira, rural udon shops off the main roads, and exploring the Kagawa countryside. For island access, Takamatsu Port is walkable from the train station.
