Why visit
Takamatsu is the strongest base because JR Takamatsu, Takamatsu Port, local Kotoden railways, airport buses and central accommodation converge within a manageable area. Tamamo Park and the maritime castle remains introduce the city's relationship with the sea; Ritsurin Garden deserves several unhurried hours; shopping arcades and udon shops fill weather gaps. The JR and Kotoden stations are close but not interchangeable for every route. Port terminals and ticket counters also differ by destination. A successful first day locates tomorrow's ferry pier before dinner rather than discovering it minutes before departure. Takamatsu can support Yashima and some island day trips, but not every island on one hotel booking.
Yashima is a plateau and historical landscape east of central Takamatsu. Train, bus and road approaches serve different points, and the summit area still involves walking. Views over the Seto Inland Sea depend on haze, rain and wind. Yashimaji, historical interpretation and lawful viewpoints create a half or full day when combined with the foot of the plateau, but a late return bus must be confirmed. Nearby cultural facilities have their own calendars. Treat the overlook as weather-dependent and avoid entering closed slopes or roadside areas for a panorama. Yashima is also an excellent place to understand how islands that appear adjacent may have entirely separate ferry routes.
Kotohira is organised around the long approach and stairs of Kotohiragu. JR Kotohira and Kotoden-Kotohira provide different connections. The shrine visit must be matched to mobility, heat and rain; the main sanctuary and higher inner shrine are different physical commitments. Shops, a theatre tradition and onsen accommodation justify an overnight or a relaxed half day, while luggage can be stored before climbing. Worship etiquette and official opening information take priority over a step-count challenge. A traveller with limited mobility can still experience the town and lower approach without being pressured into every stair.
Marugame is a practical western rail stop for Marugame Castle, the fan tradition and connections toward Kotohira or Mitoyo. The hilltop castle rewards walking, but heat, rain, construction and steep paths affect access. Confirm the current route rather than relying on an old photograph of walls or keep. The city is not simply a transfer: museum or craft context and local food can support a half day. Zentsuji and pilgrimage-related sites can be added as a separate rail or bus module, with temple etiquette. Do not turn Kotohira, Marugame, Zentsuji and Chichibugahama into a rushed checklist merely because they share western Kagawa.
Shodoshima is large enough to require its own transport plan and usually at least one night. Ferries arrive at Tonosho, Ikeda, Kusakabe, Sakate and other ports depending on origin and operator; the word Shodoshima is not a single terminal. Olive landscapes, soy-sauce history, Kankakei, coastal villages and seasonal sites are dispersed. Island buses are useful on selected corridors but may not connect every attraction or last ferry. Rental cars, bicycles and taxis require advance availability and realistic elevation. Kankakei ropeway and mountain roads respond to wind, maintenance and autumn crowds. Choose one side of the island per day and confirm the departure port before setting out.
Naoshima is best understood as a port-and-reservation day, not an unlimited open-air gallery. Ferries from Takamatsu and Uno have different timetables, vessels and ports. On the island, Miyanoura, Honmura and the museum zone are connected by limited buses, walking and rental cycles, but queues and capacity matter. Major museums and selected art houses may require dated entry and have closure days; photography is restricted in many interiors and some outdoor works remain copyrighted. Tickets do not automatically include transport or every venue. This guide uses port and landscape photography rather than reproducing artworks. Visitors should check the rights and shooting rules displayed by each institution before posting or publishing their own images.
Teshima is not a casual extension after completing Naoshima. Ferries may link it with Takamatsu, Uno, Naoshima or Shodoshima only on particular services and seasons. Ieura and Karato are separate island nodes; buses are limited and popular cycles can sell out. Teshima Art Museum and other facilities operate on dated calendars and can require reservations. The island's agricultural and coastal landscape deserves time beyond one museum, while residents' roads and private property require respect. Wind, fog or mechanical disruption can remove a sailing, so a same-day chain involving three islands is fragile even when a journey planner displays it.
Mitoyo gives western Kagawa a rural coastal counterweight. Chichibugahama's reflective photographs depend on a suitable low tide, a wet surface, light, wind and safe public access; sunset alone does not guarantee a mirror. Public transport is limited and special buses may be seasonal. Drivers still need designated parking and must protect residents' access. Mt. Shiude and the Shonai Peninsula, island ferries or temple sites are separate decisions with reservation and road constraints. Stay nearby or in Kanonji/Marugame when sunset matters, and do not schedule the last train without a verified bus or taxi.
The resilient structure is two mainland bases plus one island overnight: Takamatsu for city, Yashima and a carefully chosen art island; Kotohira or Marugame for central-western heritage; Shodoshima for an island circuit; and Mitoyo as an optional western night. The Seto Inland Sea is often calmer than an ocean coast but fog, wind, thunderstorms, typhoons, vessel maintenance and port conditions still alter services. Check operators directly on the day. Art festivals multiply demand and temporary venues but also change calendars, capacity and transport. Reservations, local meals and buffer ferries are not lost time; they are the framework that prevents one missed connection from erasing the trip.
Suggested itinerary
Nine modular days across mainland Kagawa and three island choices
This route treats Naoshima, Teshima and Shodoshima as alternatives or separate overnight modules, not a single ferry race. Reserve art facilities before transport only after confirming that the ferry and island bus can support the entry time. During festivals or typhoon periods, add further buffers and reduce the number of venues.
- 1
Day 1 · 09:30
Takamatsu orientation from castle to garden
Locate JR Takamatsu, Kotoden-Takamatsu-Chikko and the correct ferry terminals, then visit Tamamo Park and one central museum or arcade. Give Ritsurin Garden its own generous afternoon rather than squeezing it between trains. Finish with an udon shop whose current hours suit you, and inspect the next day's platform or bus stop.
Official information - 2
Day 2 · 09:00
Yashima as history and Seto geography
Use the current local train and bus or legal road approach, verifying the final return. Walk the summit area, Yashimaji and public viewpoints according to weather and mobility. Haze can obscure islands and wind can make edges uncomfortable; do not cross barriers. Return to Takamatsu before depending on a late connection.
Official information - 3
Day 3 · reserved option
Naoshima with one museum anchor
Check the operating ferry to the intended port, hold a dated museum reservation and allow island-bus queues. Build the day around one major museum plus either Honmura or Miyanoura, not every venue. Follow each site's photography and publication rules; never photograph a restricted interior or assume a ticket grants commercial reuse of an artwork image.
Official information - 4
Day 4 · alternative island
Teshima without a three-island relay
Travel only when ferries, island buses and a reserved facility align. Choose Ieura or Karato as the working gateway and leave capacity for a meal and landscape. If wind or a cancellation breaks the chain, return by the safest confirmed route. Do not trespass on fields or private lanes while looking for a photograph.
Official information - 5
Days 5–6 · overnight
Shodoshima by port-specific plan
Book the actual sailing and arrival port, then collect a reserved car or follow a bus corridor. On the first day combine one olive or soy-sauce area with a nearby coast; on the second choose Kankakei or another mountain objective after checking ropeway, road and visibility. Avoid a full-island loop with a fixed last ferry.
Official information - 6
Day 7 · 10:00
Kotohira at a humane stair pace
Leave luggage, assess heat and wet steps, and visit the lower town and as much of Kotohiragu as safely suits your mobility. The inner shrine is an additional climb, not an automatic requirement. Stay for local history, theatre context or onsen rather than racing onward immediately.
Official information - 7
Day 8 · 09:30
Marugame and western craft context
Travel by rail, check the current castle access and climb only in suitable heat and weather. Add a fan or museum stop before lunch. Continue to a western base only with a confirmed local connection; Chichibugahama sunset requires its own transport plan.
Official information - 8
Day 8 · sunset window
Chichibugahama by tide and transport, not promise
Check the official tide guidance, sunset, weather, parking or seasonal bus. Use the public beach responsibly, avoid blocking other visitors and protect the tidal environment. If wind, rain or tide prevents a reflection, enjoy the coast without manufacturing unsafe poses. Confirm the return before darkness.
Official information - 9
Day 9 · optional
Mitoyo peninsula or pilgrimage module
Choose one: a reserved and open Mt. Shiude plan, a lawful coast drive, or a temple and town visit. Road access, seasonal shuttle requirements and parking can change. Do not combine a remote peninsula sunrise with a rushed ferry or flight. Return toward Takamatsu or Okayama with a full transport buffer.
Official information - 10
Departure day
Use a mainland buffer after the islands
Sleep in Takamatsu or near the correct onward station after the final island. Check ferry and rail status before leaving accommodation, return rental equipment and retain time for a different sailing if available. A cancelled final boat should not automatically cause a missed international flight.

Best time to visit
Spring
Island walking with festival and holiday demand
Comfortable temperatures suit Takamatsu, Kotohira and island cycling, though wind and rain still affect ferries. Cherry blossom periods and Golden Week fill transport and lodging. Art-event years add reservation pressure and temporary timetables. Book dated museums, cycles and island rooms early, then confirm the operator again near travel.
Summer
Sea light with heat, storms and limited shade
Long days help island schedules, but humid heat is serious on shrine stairs, exposed beaches and cycle routes. Thunderstorms and typhoons can interrupt boats and bridges. Start early, carry water, use buses where sensible and reduce outdoor distance. A museum reservation does not oblige you to travel during a safety suspension.
Autumn
Popular Seto travel and Kankakei crowds
Later autumn can offer clear air and colour, especially on Shodoshima, but ropeway, roads, ferries and accommodation become crowded. Early autumn retains typhoon risk. Art festivals may concentrate visitors across small ports. Leave a sailing earlier than the last one and avoid a car schedule that depends on perfect parking.
Winter
Quieter islands with wind and reduced calendars
Mainland cities and udon travel can be comfortable, while cold wind changes ferry decks, Yashima and beaches. Some island facilities, buses and restaurants reduce days or hours; art venues can close for maintenance. Snow is uncommon at the coast but inland roads can still freeze. Verify every essential facility before buying a non-refundable connection.

Getting there and around
Takamatsu's rail, airport and port nodes
JR Takamatsu, Kotoden-Takamatsu-Chikko and the port are close but serve different systems. Airport buses use designated stops. Identify the pier, ticket counter and boarding deadline for the actual island operator.
Takamatsu is a strong base for one island day when a confirmed return exists. It is not proof that Teshima, Naoshima and Shodoshima connect conveniently on the same date.
Mainland rail toward Marugame, Kotohira and Mitoyo
JR trains connect Takamatsu with Marugame, Zentsuji, Kotohira-side services, Kanonji and onward Shikoku routes; Kotoden provides a separate Takamatsu–Kotohira option. Check the station that best fits the shrine approach and hotel.
Mitoyo beaches and peninsula points require limited buses, seasonal shuttles, taxi, bicycle or car. Sunset happens after some services finish. Reserve the return rather than assuming a taxi will appear.
Naoshima and Teshima ferry logic
Takamatsu and Uno are major gateways, but high-speed passenger boats and car ferries differ in capacity, bicycle rules and ports. Some services do not operate daily or seasonally. Read the operator timetable and disruption notice.
Island buses cannot absorb unlimited arrivals. Allow queues between ferry and timed museum entry, and keep an earlier return sailing. Tickets for art and transport are normally separate.
Shodoshima's multiple ports
Select Tonosho, Ikeda, Kusakabe, Sakate or another port according to the exact sailing and island itinerary. A rental car reserved at one port may not be waiting at another. Bus passes only help when routes serve the chosen sites.
Mountain roads and the Kankakei ropeway can be affected by wind, maintenance and crowding. Overnighting removes pressure from the last ferry and supports a smaller daily area.

Local food recommendations
7 local food recommendations
Sanuki udon
Kagawa's defining noodles appear in self-service shops, seated restaurants and specialist styles. Opening hours can be morning-focused and popular shops may sell out. Learn the tray, topping and return procedure, order a modest first bowl and compare two areas instead of attempting an exhausting numerical challenge.
Official informationHonetsukidori
Marugame's bone-in seasoned chicken is commonly served as tender young bird or firmer mature bird, with rich juices and spice. It is a substantial meal rather than an udon side quest. Popular restaurants can queue; wash hands and keep alcohol separate from driving.
Official informationShodoshima soy sauce and tsukudani
Shodoshima has a long fermented-food industry. Visit an operating brewery or museum that publishes current tour rules, and compare aroma, ageing and ingredients. Production areas are workplaces; do not enter restricted buildings. Bottles and preserves need storage and baggage planning.
Official informationShodoshima olives and olive somen
Island olive products include oil, fruit preparations and foods using olive leaves or oil, while somen has its own local production history. Quality, origin and harvest vary. Taste at a reputable producer or shop and do not infer that every green-coloured product has the same ingredients.
Official informationAn-mochi zoni
Kagawa's New Year soup famously pairs white miso with a sweet bean-paste rice cake. Availability outside the holiday season depends on specialist cafes or restaurants. Treat it as a specific regional contrast of sweet and savoury and check allergens in miso, stock and mochi.
Official informationSetouchi fish
Sea bream, octopus and other Seto Inland Sea catch appear by season and port. Menus are not guaranteed daily, and working harbours are not self-service markets. Choose a restaurant that explains the day's fish and ask about preparation and price before ordering.
Official informationWasambon sweets
Traditional fine sugar associated with eastern Shikoku appears in shaped dry sweets and modern desserts. Makers and raw-material claims differ. Buy from an established producer, protect delicate pieces in luggage and enjoy them with tea rather than treating every pale sweet as certified wasambon.
Official informationFrequently asked questions
Can I visit Naoshima, Teshima and Shodoshima in one day?
Do not plan a first trip that way. Ferry routes, museum reservations and island buses rarely align with meaningful visits to all three. Choose one art island per day and give Shodoshima one or two nights.
Does a museum ticket include the ferry and island bus?
Normally no. Art admission, ferry, bus, rental cycle and luggage are separate unless a specific product states otherwise. Check the named operator and venue, and allow queue time before a timed entry.
Can I freely photograph and publish every artwork?
No. Contemporary artworks remain protected and venues set photography, social posting and commercial-use rules. Follow signs and staff. This guide intentionally uses landscape and transport images rather than reproducing artworks as its subject.
Will ferries run because the Seto Inland Sea looks calm?
Appearance from one port is not an operating decision. Wind, fog, thunderstorms, typhoons, mechanical issues and port conditions can delay or cancel service. Check the ferry company directly and keep an earlier return.
Do I need a car?
No for Takamatsu, Kotohira, Marugame and a carefully planned Naoshima day. A reserved car is useful on Shodoshima and in western Mitoyo, but ferries may have vehicle limits and mountain roads or parking require care.
Is the Chichibugahama mirror effect guaranteed at sunset?
No. It depends on tide, surface water, cloud, wind, light and safe access. Use the official forecast guidance and value the beach even without a reflection. Never disturb pools or block others for a staged image.
Can visitors with limited mobility enjoy Kotohira?
Yes, but the shrine stairs require an individual assessment and the inner shrine is an additional climb. Enjoy the lower town, cultural sites, food and onsen, and consult official accessibility information rather than accepting pressure to complete every step.
