About Cycling Shimanami

Attracting thousands of cyclists from Japan and all over the world, Cycling Shimanami is a non-competitive public cycling event that takes place on the Shimanami Kaido Expressway every two years. During the event, participants will be able to freely cycle on the expressway’s roads, as the sections covered in the courses will be closed off to cars and other vehicles.

Cycling Shimanami is an easy event to get into even if you don’t speak Japanese – brochures with complete information on routes and course details are available in multiple languages: English, Korean, Traditional Chinese and Simplified Chinese.

Shimanami Kaido Expressway

Although biking on an expressway might at first seem like a bad idea, the Shimanami Kaido is a beloved route among cyclists in Japan. In addition to having unrivaled views from the Seto Inland Sea, its roads have seen massive improvements over the years in an effort to make the expressway very cycling friendly. 

Locally known as a “Sacred Place for Cyclists”, Shimanami Kaido is structured with dedicated cycling lanes painted with a bright blue line that guides cyclists so they won’t get lost. Throughout the surrounding area, over 150 shops, cafes, and guest houses are more than happy to welcome cyclists in. They provide essentials such as air pumps, bicycle stands, drinking water and toilets. Certain buses, trains, and ships that service the area also accept cyclists with their bikes onboard.

Thanks to all of this and more, Shimanami Kaido is considered to be a world-class cycling course and officially became a “National Cycle Route” in November 2019.

Course Categories

Cycle access ramp at Imabari

Course A: Imabari 70

If you want to experience the entire length of the main highway course without the round trip aspect, Imabari 70 will get you there.

Course C: Omishima 100

Preventative Measures Against COVID-19 for Cycling Shimanami 2022

Participants are expected to abide by the rules set by the event organizers. This includes agreeing to withdraw from the event in cases such as having a body temperature of 37.5°C or above, testing positive for Covid within three weeks of the event, or being in close contact with someone who tested positive within two weeks prior to the event. 

Participants will also be given a health check app or sheet to complete two weeks before Cycling Shimanami. This information will then be verified at the check-in counter on the day of the event. During check-in, other preventative measures will be enforced, such as measuring body temperatures at the entrance, wearing of face masks, hand-disinfecting, and the provision of a bag for belongings that will be submitted during check-in and handed back after crossing the finish line.

Once the cycling event is underway, masks will be required before starting, during aid station stops, and after crossing the finish line. Outside of these instances, it is up to participants’ discretion whether to wear masks while on the road. To avoid the risk of heat stroke, mask-wearing is not strictly enforced during cycling.
