Iya Valley Guide: Vine Bridge, Boat and Bus Planning

JGO! editorial team — WEBMARKS Inc. (Fujisawa, Kanagawa)

Iya Valley visitors can combine a walk across Iya Kazurabashi, the vine bridge at Zentoku, with a sightseeing boat on Oboke Gorge. The two attractions have different operating hours, ticket arrangements and weather restrictions, so check each one separately before setting out. This guide focuses on the bridge, the Oboke boat and the bus connections described by the operators; it does not assume that their conditions apply to other bridges or attractions in the wider valley.

Prices, hours and transport information below were checked on 4 November 2026. They are useful for planning, but they are not a guarantee that an attraction will operate on a particular day or that a bus connection will suit your itinerary. Use the official pages linked here to confirm the details for your travel date, especially if a crossing, boat ride or last bus is essential to your plans.

Iya Kazurabashi: location, crossing hours and prices

Iya Kazurabashi is at 162-2 Zentoku, Nishiiyayamamura, Miyoshi. Miyoshi tourism describes it as 45 metres long and two metres wide, with the river about 14 metres below; the bridge is rebuilt every three years. From Kazurabashi Yumebutai, the listed walk to the bridge is approximately five minutes. See the Miyoshi tourism bridge page for the current attraction information.

The bridge’s published crossing hours change by season. Use the seasonal bands below as the listed hours for crossing—not as opening hours for the evening illumination, which is a separate activity.

The normal crossing fare is ¥550 for visitors of junior-high-school age and older, ¥350 for elementary-school children, and free for preschool children. For groups of at least 20, the bridge page lists ¥500 per adult and ¥320 per elementary-school child. The bridge’s group threshold and the boat’s group threshold differ, so do not assume that qualifying for one group rate qualifies your party for the other.

The bridge page lists PayPay as an available payment method. If you intend to use it, check the page’s current payment information rather than relying on a past listing. Standard-car parking at Kazurabashi Yumebutai is listed at ¥500. The bridge page also lists a walk of about five minutes from the parking area, so allow for that walk as well as time to park and buy or use tickets.

The bridge cannot be crossed during the listed 19:00–21:30 illumination. In other words, arriving while the bridge is lit does not mean you can walk across it. If crossing is the main reason for your visit, plan around the daytime seasonal hours and check whether a temporary closure has been announced before you travel.

Bad weather can also affect access: the attraction may close temporarily in conditions such as a heavy-rain warning. The seasonal schedule should therefore be treated as the normal published crossing window, not a promise that the bridge will be open throughout it. Check the official bridge information close to your visit, particularly when the weather is unsettled.

When checking opening information, use the bridge’s individual attraction page for its current three-season schedule. The Miyoshi tourism FAQ and the individual bridge page have differing seasonal-hour information, so it is prudent to confirm the crossing hours directly on the bridge page rather than combining figures from separate pages. This matters most if you are planning around the final part of the day.

Getting to the bridge by bus or car

Shikoku Kotsu revised its route-bus timetable on 1 October 2026. Its current route information describes three services relevant to planning around Kazurabashi Yumebutai: the Nishi-Iya route connects the Awa-Ikeda and Oboke area with Yumebutai; the Higashi-Iya route runs between Yumebutai and Kubo; and the Iya Valley route runs between Yumebutai and Hotel Iya Onsen. Check the operator’s current route-bus information for the timetable and connections for your actual date.

Treat these as separate services rather than as one continuous route through every point in the valley. In particular, Shikoku Kotsu identifies Yumebutai as the transfer point for travellers coming from the Oboke direction who want to use the Iya Valley route. The route descriptions tell you which services connect the named areas, but they do not by themselves establish a convenient departure or return time. Check the outbound and return journeys together before deciding how long to spend at the bridge.

A practical bus-planning sequence is to choose the day you intend to travel, open the operator’s current timetable, identify the service that reaches Yumebutai, and then check the onward or return service you need. If your plan involves changing buses at Yumebutai, confirm the relevant times for both services rather than assuming they connect closely. For route questions, the Awa-Ikeda bus terminal contact listed by Shikoku Kotsu is 0883-72-1231.

The operator says the child fare applies through elementary school and is half the adult fare, with fractions of five yen rounded up. It also lists one free preschool child per fare-paying passenger under its stated condition. These are bus-fare rules, not the bridge’s admission rules: the bridge separately lists free entry for preschool children and its own standard and group prices. If you are travelling with children, check the fare for the actual service and group before boarding.

By car, Miyoshi tourism gives an approximate drive of one hour to the bridge from either Ikawa-Ikeda IC or Otoyo IC. This is an estimate rather than a guarantee for a particular road, traffic or weather condition. The tourism guidance recommends entering the Kazurabashi Yumebutai navigation telephone number, 0883-87-2200, rather than the tourist information office. Use that destination when setting your navigation system, then allow for the listed parking charge and the walk from Yumebutai to the bridge.

For either mode, the important planning distinction is between reaching the bridge and having enough time to cross it. A bus schedule may limit how long you can stay, while a car journey still needs to fit within the seasonal crossing hours. If the bridge is a priority, check both the day’s operating information and your return transport before leaving your starting point.

Oboke Gorge sightseeing boat: tickets, duration and conditions

The Oboke sightseeing boat is a separate activity from the vine bridge. The operator lists operating hours of 09:00–17:00 and a last departure at 16:30. A round trip takes approximately 30 minutes and covers about four kilometres. The 17:00 end of operating hours is not an extra departure time: plan around the stated 16:30 last departure.

Tickets are sold at the first-floor front desk of Restaurant Mannaka. The operator says that individuals and groups do not need reservations, that boats operate as visitors arrive, and that one person can board. This means a reservation is not listed as necessary; it does not remove the need to check whether the service is running on the day. For current operating details, consult the Oboke Gorge sightseeing boat page.

The fare revision effective 1 September 2026 lists ¥1,800, including tax, for an adult and ¥900, including tax, for a child aged three through elementary school. For groups of at least 15, the listed fares are ¥1,620 per adult and ¥810 per child. The operator’s fare revision notice gives the revised prices; check the current fare before buying.

These age bands are not identical to the bridge’s. For a boat passenger, the listed child fare applies from age three through elementary school; the bridge lists elementary-school admission and free entry for preschool children. Calculate the two activities separately for each child rather than using one attraction’s age category for the other.

For example, at the listed individual rates, one adult and one eligible child aged three through elementary school would pay ¥2,700 for the boat before transport or other purchases. Two adults would pay ¥3,600 at those rates. These are simple totals from the cited fares, not package prices, and they do not include the bridge, parking or travel between activities. Recheck the fare and the child’s eligibility before purchasing.

The operator says trips may be cancelled because of high water, strong winds, storms or similar conditions. When water levels are low, the ride may be shortened. These conditions can change the plan even when the attraction’s listed operating hours have not ended, so check the boat operator’s information rather than relying only on the clock.

Passengers must wear life jackets, complete one passenger list per group, and may not smoke on board. Pets are not permitted, except for assistance dogs. The passenger list and safety requirements are part of the boarding process, so allow time for them in addition to the approximately 30-minute round trip and the journey to the ticket desk. The boat operator’s page is the appropriate place to confirm current arrangements.

Planning both activities in one visit

The bridge and the boat can be combined, but their schedules and operating decisions are independent. The bridge has seasonal daytime crossing hours and may close temporarily in bad weather; the boat has a listed final departure of 16:30 and may be cancelled or shortened according to water and weather conditions. A plan that works for one attraction does not automatically work for the other.

The bridge prices and seasonal hours are listed by Miyoshi tourism; the boat’s hours and boarding information are on the operator’s sightseeing-boat page, and its revised fares are in the fare notice. The listed prices were checked on 4 November 2026. They exclude travel between the attractions and should be confirmed for your date.

If you are travelling by bus, check the route and return timetable before choosing the order or length of your stops. If you are driving, allow time for the journey between attractions as well as parking, walking, ticket purchase and the activities themselves; the information here does not establish a travel time between the bridge and boat. In either case, avoid treating the boat’s 17:00 closing time as a departure, or the bridge’s evening illumination as a crossing opportunity.

For a group, compare the thresholds before assuming a discount applies to the full day. The bridge’s listed group rate begins at 20 people, while the boat’s begins at 15. The two rates also have different child categories, so confirm each attraction’s applicable fare for the actual composition of your party.

Weather checks matter even when the two attractions are on the same itinerary. A bridge closure does not establish that the boat is cancelled, and a boat cancellation does not establish that the bridge is closed; each operator describes its own conditions. Check both official sources on the day if conditions are poor or changing, and keep enough flexibility to adjust the plan.

Frequently asked questions

Can I cross Iya Kazurabashi during the evening illumination? No. Miyoshi tourism says the bridge cannot be crossed during the listed 19:00–21:30 illumination. Plan a crossing within the seasonal daytime hours instead, and check the current bridge information for temporary closures.

Is the Oboke boat guaranteed to operate until 17:00? No. The operator lists 17:00 as the operating-hours end and 16:30 as the last departure, and weather or water conditions can affect service. Check the boat operator’s current information before travelling to the ticket desk.

Can I visit the bridge and boat without a car? The current Shikoku Kotsu route information describes services connecting the Awa-Ikeda and Oboke area with Yumebutai, as well as routes from Yumebutai toward Kubo and Hotel Iya Onsen. It identifies Yumebutai as the transfer point for travel from the Oboke direction onto the Iya Valley route. Whether a particular day’s bus schedule lets you visit both attractions and return as planned depends on the current timetable, so check the outbound and return journeys before setting your itinerary.

Where do I buy a boat ticket? The operator directs passengers to the first-floor front desk of Restaurant Mannaka. It says individual visitors and groups do not need reservations and that one person can board, but service remains subject to operating conditions. Allow time to buy a ticket and complete one passenger list per group.

Can pets ride on the boat? The operator says pets cannot board, except for assistance dogs. If you need to clarify a specific circumstance, contact the operator rather than assuming that another attraction’s policy applies.

Does the bridge information here apply to Oku-Iya Double Kazurabashi? No. Oku-Iya Double Kazurabashi is a separate attraction, and the current operating conditions for it have not been confirmed here. Do not use the hours, fares or weather information for Iya Kazurabashi as a substitute; check the separate attraction’s current information before planning a visit.
