NOTE: It appears that the gravel road across the pass from Setana to Shimamaki may be impassible due to nature retaking the road (overgrown, landslides etc., see Phil’s comment on Day 3’s blog post). The alternative is the beautiful stretch of coastal road to the west.
This is a 230km cycle tour along the west coast of the Oshima Peninsula at the southern end of Hokkaido. The Japan Sea coast along the western side of this peninsula is rugged and drop-dead gorgeous. Think ultra-clear water, rocky outcrops, and big views. Take the coast the whole way round to Shimamaki, or head inland over the closed gravel road to get properly off the beaten track. The route starts and finishes at JR train stations with direct train services to Sapporo City. This makes it a nice route for a few nights' getaway from the big city.

Route Overview

Just like in 2013 and 2014, Haidee and I spent 2015’s Golden Week holidays (a string of back-to-back public holidays in Japan) to explore a little bit more of Hokkaido, Japan’s large northern-most island. This year, Dirk joined in on the fun too. Unlike previous years however, in order to take in vistas further afield we jumped on a train with our bikes and started the five day tour at Onuma Lake Park; some 275km or so southwest of Sapporo.

The plan was to cycle back towards Sapporo, following more or less the Japan Sea coast of southwestern Hokkaido. We wouldn’t cycle the full distance back to Chitose however (we now live in Chitose). The plan was to head to Niseko, and then hoof it back to Chitose by train.

All in all, the trip was a great success: the gravel road route I had scouted out ended up being snowed under (which allowed for my first ever experience of having to turn back during a cycle tour); we saw raging rivers; placid seas; roaring seas; had gusting 40km/h tailwinds; and great company along the way.

  • Getting there: There are a couple of main Japan Rail train lines that head from the top of the Oshima Peninsula to Sapporo. The Muroran trunk line goes via the Muroran coast and Tomakomai, and the Hakodate trunk line goes to Sapporo via Niseko and Otaru. This allows for a horseshoe loop tour from Onuma on the former to the sleepy town of Kuromatsunai on the latter, via the gorgeous Japan Sea coast on the western side of the Oshima Peninsula.

  1. Hello, we are thinking of following this route in July. Thank you for all the information. Couple questions. We are riding first around Biei and Furano towards Tomakomai. Then take the train to Oshamambe. Then follow your route but end in Hakodate to take the ferry to Oma and begin riding again. Since this took you 4 days and we will add on the first part we are hoping a leisurely 9 days will be ok? We thought of adding Okushiri island but thought we would be to tight for time.

    Thanks again for your wonderful website, I enjoy following you on instagram! Jodie

    1. Hi Jodie, thank you for the comment! Nine days certainly sounds doable – we kept daily distances fairly short, so if you need to, you’d be able to combine days. I hope you enjoy!
