Shimanami Kaido Cycling: Bikes, Prices and Route Planning

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

The Shimanami Kaido links Onomichi in Hiroshima Prefecture with Imabari in Ehime Prefecture, crossing islands in the Seto Inland Sea. The full route is about 70 km, but riding from one end to the other is not the only way to experience it: you can choose a shorter outing that better suits your group, pace and return arrangements. Start by deciding how far you want to ride, then match the bike and rental location to that plan.

Shimanami Japan lists adult cross bikes and city cycles at ¥3,000 per day, while electric-assist bikes, E-bikes and tandems have different prices and return conditions. Reservations are strongly recommended, especially during busy periods, but the English guide does not say that they are mandatory. Check the current rental information before travelling, since the bike you choose can affect where and when you must return it.

Choose a distance and return plan

The approximately 70 km figure describes the ride from Onomichi to Imabari, not a promise that every rider will complete it within a particular time. Shimanami Japan advises beginners and other riders to plan for up to around 10 hours for the full route. Stops, riding pace and the conditions on the day affect how long your own trip takes, so treat that figure as a planning guide rather than a guaranteed schedule. (Shimanami Japan: English bike-rental guide)

JNTO describes the cycling route as crossing nine bridges between islands and notes that model courses are available for different abilities. Use that range of options as a reason to choose your ride around your party, rather than assuming that the only worthwhile plan is to ride between both cities. If a full crossing does not suit everyone, decide on a shorter section and confirm in advance which rental locations can accept your particular bike. (JNTO: Cycle the Shimanami Kaido)

Before choosing a start time, compare your intended distance with your expected pace, planned breaks and the closing time of the return location. This is especially important when a bike has to be returned within the same day’s business hours. An early return does not necessarily mean a lower rental cost: Shimanami Japan says it does not refund the price difference when a bike is returned earlier than planned.

A practical planning sequence is:

1. Decide whether your group wants to attempt the full approximately 70 km route or ride a shorter section.
2. Compare the rental bike types and their return conditions on the operator’s English guide.
3. Check the hours of the actual rental location and work your intended ride around its closing time.
4. Allow time for your own pace and stops; the operator’s up-to-around-10-hour advice is not a fixed timetable.
5. Confirm current route and rental instructions before setting out.

Some travel videos can help you picture different approaches to the route, but they are personal perspectives rather than current rental instructions. Miya Days’ video presents an early-summer ride from Onomichi to Ikuchijima, while Solo Travel POV’s video shows a journey in the opposite direction, from Imabari to Onomichi. For current distances, bike availability and return conditions, rely on the operator’s information rather than a video’s trip details.

Rental bikes, prices and return rules

The published daily prices below show why it is useful to choose a bike by both cost and return flexibility. The listed price is not a complete quote for every party or date: confirm current stock, the correct child category and any applicable terms directly with the operator before booking. The operator’s current booking information should also be checked for payment, deposits, cancellation rules and any other charges; those details are not established by the information summarised here.

These prices and conditions are listed by Shimanami Japan, checked 5 November 2026. Do not assume that one bike’s return rule applies to another: the all-location return condition is stated for cross bikes, while tandems must go back to their rental location and E-bikes have a same-day business-hours return condition. For city cycles and electric-assist bikes, confirm the return arrangement for the particular rental rather than inferring it from the cross-bike rule.

Shimanami Japan says that it lends a helmet free to people who rent a bike, but it does not rent helmets separately. If you need a helmet without renting a bicycle, the information available here does not establish a separate rental option. The operator also says that returning a bicycle early does not qualify for a refund of the price difference, so choose your booking period with that policy in mind.

Child-bike information needs particular care. The Japanese price page describes the child category as elementary-school age and younger, while the English guide uses different wording for the age category. Ask the operator to confirm which category applies to your child. The English guide asks customers requesting a children’s bike to enter the child’s height in the reservation notes, and the price page says that kid-sized bikes are not stocked at the Imabari Station-front location. Confirm availability at your intended rental point rather than assuming that a child’s bike can be collected everywhere.

For another traveller’s account of cycling and costs, see Josh Kwan’s Shimanami guide video. A video may be useful context, but its cost details can reflect a different date or rental choice. Use the operator’s price page to confirm the published price and conditions for your own dates.

Reserve the right bike for your group

Shimanami Japan strongly recommends booking ahead, although its English guide does not make a reservation mandatory. Bikes held for day-of rental are first come, first served, and availability is not guaranteed. The operator identifies spring, autumn, Golden Week and Obon as busy periods, so it is particularly sensible to check availability early if you plan to ride during one of them. (Shimanami Japan: English bike-rental guide, checked 5 November 2026.)

For an Onomichi rental enquiry, the Onomichi tourism association directs customers to Shimanami Japan and lists 0848-22-3911 as a reservation contact. Confirm the current contact details, rental terminal and language support directly before relying on the number. The association’s information is available on its cycle-rental page.

Before submitting a booking, compare the needs of every rider rather than reserving only by total bicycle count. Check each requested bike type, the sizes or child-bike details your party needs, where the bike can be returned and when that location closes. A booking for one bike does not establish that another type can use the same return terminal or be brought back later.

For a child-bike request, enter the child’s height in the reservation notes as the operator’s English guide asks. Then review the current price, payment and cancellation terms shown during the booking process. The information here does not establish deposit or cancellation amounts, so do not assume that they are included in the published daily rental price.

A useful booking checklist is:

• Open the English rental guide and select your intended date and rental location.
• Check the type and number of bikes requested, including child-bike availability and the child’s height where relevant.
• Confirm the return location and closing-time conditions for each type of bicycle.
• Review the current total, payment instructions and cancellation terms before completing the request.
• Keep your confirmation and the operator’s contact information available for the day of the ride.

Starting at Imabari Itoyama

Do not confuse the former Sunrise Itoyama facility with the cycle-rental service at Imabari Itoyama. Imabari City says Sunrise Itoyama closed on 31 March 2026, while the Imabari Itoyama cycle rental continues operating. A closure notice for the facility therefore does not, by itself, mean that the rental service has also closed. Check the municipal information and any current rental notice before travelling. (Imabari City: Itoyama information, checked 5 November 2026.)

The city lists seasonal rental hours of 08:00–19:00 from March through November and 08:00–18:00 from December through February. Its regular-closure field says there are no regular holidays. These are the hours and closure details listed by the city; check for current notices before your visit, and plan your return around the closing time if your chosen bike has to be returned during business hours.

Use the listed address, 2-8-1 Sunabacho, Imabari, when checking a map or arranging transport; a map search for the rental location is available. The station access figures and parking information come from the Imabari City listing. The stated parking capacity does not guarantee that a space will be available, and actual train, taxi and parking conditions should be checked for your travel date.

The station information matters when you are deciding how to reach the rental point, not just how to ride away from it. JR Hashihama Station is listed as about a 25-minute walk from the rental location, but limited-express trains do not stop there. JR Imabari Station is listed as about 15 minutes away by taxi. Arrange your approach and onward transport separately from the bicycle rental; the rental itself should not be treated as an inclusive travel ticket.

Practical preparation for a smoother ride

Make the rental decision and the return plan together. First, identify the bike type each rider needs; then confirm its return rules and the opening hours of the location where it must be returned. This avoids relying on the cross-bike all-location return policy for a tandem or E-bike, which has different stated conditions. If your plans include an electric-assist bike for more than one day, note that multi-day use is available but confirm the specific return arrangements with the operator.

For groups, compare each rider’s preferred bike, any relevant size information and the longest distance everyone wants to cover. The full route is about 70 km, and the operator advises allowing up to around 10 hours for beginners and others attempting it, so a group’s plan should reflect the pace of the riders who will be travelling together. If that distance or time does not suit the group, consider a shorter ride and verify the rental and return locations for that choice. (Shimanami Japan)

Save the rental operator’s contact details before departure and check what to do if a bike develops a problem. Shimanami Japan’s English guide says to contact the operator first in the event of a breakdown. Confirm the current procedure and the service available for your route rather than assuming that roadside help or a particular repair arrangement is provided. (Shimanami Japan: English bike-rental guide)

Plan transport to and from your chosen rental terminal as a separate part of the trip. This is especially important when starting at Imabari Itoyama, where the city lists access from JR Hashihama Station and JR Imabari Station separately, and notes that limited-express trains do not stop at Hashihama. If your chosen bicycle must be returned within business hours, check the applicable seasonal closing time and leave enough of your own planned ride for the return.

The current bridge tolls and any other route charges are not established by the information used for this guide. Check them separately before setting a trip budget rather than adding an unverified amount to the bicycle rental price. The same caution applies to day-of bicycle stock, deposits and cancellation fees: consult the operator for current details.

For broader trip planning, see our [Hiroshima travel guide], [Ehime travel guide] and [things to do in Ehime]. These guides can help with the areas around the route, while the rental operator and municipal information remain the sources to check for current bicycle conditions and Imabari Itoyama details.

Josh Kwan’s additional cycling video offers another traveller’s perspective. Two Wheel Cruise’s video is an indoor cycling workout based on the route, rather than a report of current rental conditions.

Frequently asked questions

How long is the Shimanami Kaido, and how much time should I allow?

Shimanami Japan describes the ride from Onomichi to Imabari as about 70 km and advises beginners and other riders to plan for up to around 10 hours for the full route. That is an approximate planning recommendation, not a guaranteed completion time. Your pace, stops and the day’s conditions affect your own schedule, so compare your plan with the bike’s return deadline and the rental location’s closing time. (Shimanami Japan)

Do I have to reserve a bicycle?

No: the English guide strongly recommends reservations but does not say that they are mandatory. If you try to rent a bike on the day, the available bicycles are first come, first served and availability is not guaranteed. The operator identifies spring, autumn, Golden Week and Obon as busy periods, making advance checks especially useful at those times. (Shimanami Japan)

Can I return a rental bike at any location?

Not every bike has the same return rule. Shimanami Japan says cross bikes may be returned at all its locations, but a tandem must return to the location where it was rented and an E-bike must be returned within the same day’s business hours. Confirm the return arrangement for your particular bike before booking; do not assume that another type shares the cross-bike rule. (Shimanami Japan rental prices and conditions)

Are helmets included with a rental?

Shimanami Japan says helmets are lent free to people who rent a bicycle. It does not rent helmets on their own, so a helmet-only rental is not established by the operator information summarised here. Confirm the current rental instructions if you have a specific equipment question. (Shimanami Japan rental prices and conditions)

Is cycling rental still available at Imabari Itoyama?

Imabari City says Sunrise Itoyama closed on 31 March 2026, but the Imabari Itoyama cycle rental continues operating. The city lists seasonal hours of 08:00–19:00 from March through November and 08:00–18:00 from December through February, with no regular holidays listed. Check the latest municipal and rental notices before visiting, since the closure of Sunrise Itoyama and the rental service’s status are separate matters. (Imabari City)

What should I check when booking a child’s bike?

Check the correct child category directly with the operator, because the Japanese price page and English guide use different wording for the age category. The English guide asks you to include the child’s height in the reservation notes when requesting a children’s bike. The price page says kid-sized bikes are not stocked at the Imabari Station-front location, so confirm availability at the location you plan to use. (Shimanami Japan rental prices; English bike-rental guide)

What should I do if a rental bike breaks down?

Shimanami Japan’s English guide says to contact the operator first if a bike develops a problem. Save the operator’s contact details before you start and check the current procedure for your rental and route. Do not assume that a particular repair, recovery or roadside service is included unless the operator confirms it. (Shimanami Japan: English bike-rental guide)
