Miyakojima’s () bridge-crossing itineraries can be divided into separate directions: towards Irabu and Shimojishima, towards Ikema, and towards Kurima. Official tourism information confirms how the islands are connected by bridges, but this does not mean every segment can be completed in a fixed amount of time. Based on official information checked on 29 October 2026, this article explains how to divide the routes and distinguish beach restrictions. For other attractions, see the Miyakojima travel guide.

Key points

  • Irabu Bridge () connects Miyakojima with Irabu Island ().
  • Its officially listed length is 3,540 metres, and it is described as Japan’s longest toll-free bridge.
  • Irabu Island is connected to Shimojishima () by another bridge. Official information states that Irabu Island has no scheduled ferry route.
  • Ikema Bridge () and Kurima Bridge () connect Miyakojima to Ikema and Kurima islands respectively.
  • Official information says Funakusu and Ikizu beaches on Ikema Island have no facilities or lifeguards. Their position on a bridge route does not make them supervised swimming areas.

Bridges and islands: Understanding the connections first

Route module Main bridge Officially confirmed connection Planning focus
Irabu direction Irabu Bridge Miyakojima to Irabu Island Starting point for a bridge-viewing route
Shimojishima direction Bridge between Irabu and Shimojishima The islands are connected by another bridge Can follow the Irabu section, but check activity locations separately
Ikema direction Ikema Bridge Miyakojima to Ikema Island Separate coastal sightseeing from beach activities
Kurima direction Kurima Bridge Miyakojima to Kurima Island Can be planned as a separate short bridge segment, without assuming a fixed completion time

This table compares connections, not rankings by distance or travel time. The different directions do not have directly comparable start and end points, so no conclusion such as “which bridge is fastest” is given.

Irabu and Shimojishima: One direction with connecting segments

Irabu Bridge is 3,540 metres long and is described by the official tourism page as Japan’s longest toll-free bridge. After crossing it to Irabu Island, another bridge leads to Shimojishima. Official information also explicitly states that there is no scheduled ferry service to Irabu Island.

Journey stage Key point What not to confuse
Miyakojima to Irabu Island Connected by Irabu Bridge Bridge length is not driving time
Irabu Island to Shimojishima Connected by a bridge between the islands Do not treat both islands as the same attraction or activity segment
Confirm transport mode Plan road travel based on the bridge connections Do not plan a fixed ferry service to a place without scheduled ferries

If the itinerary allows only some bridge crossings, first retain the Irabu section, then decide whether to continue to Shimojishima based on actual transport and activity conditions that day. This is a way to combine route sections, not a claim that driving times for each are verified.

Ikema and Kurima: Two directions to plan separately

Ikema Bridge leads to Ikema Island (), while Kurima Bridge connects to Kurima Island. They can be separate bridge-crossing themes; there is no need to force every bridge into the same outing.

Destination Confirmed information What to distinguish when planning
Ikema Island Connected to Miyakojima by Ikema Bridge Viewing the bridge and sea is not the same as having a beach suitable for swimming
Funakusu and Ikizu on Ikema Island Officially described as having no facilities or lifeguards Do not list them as supervised beaches
Kurima Island Connected to Miyakojima by Kurima Bridge Do not calculate travel minutes from the existence of a bridge alone

The official information about a lack of lifeguards at Funakusu and Ikizu applies to these two beaches. It cannot be used to infer identical lifeguard arrangements at every other Miyakojima beach. For beach activities, see Miyakojima swimming and snorkeling safety.

Choosing a bridge-crossing route

Main goal Module to consider Conditions to check first
Understand a long bridge and how islands are connected Irabu Bridge and Irabu Island Actual driving and activity arrangements
Continue to Shimojishima Shimojishima after Irabu Island Treat the extension separately without assuming an unverified fixed driving time
See coastal scenery towards Ikema Ikema Bridge and Ikema Island Do not treat beaches without lifeguards as supervised swimming areas
Shorten bridge-crossing activities Retain only the Kurima or Ikema direction Do not assume all bridges must be visited

A reminder

This summarizes bridge and beach information; it does not mean that any road crossing or coastal activity will necessarily be open on the day. Transport and on-site rules may change. Check the latest official information before departure.
