I'm planning a tour September - November from Seoul in South Korea, down official bike routes to Busan, then ferry to Fukouka in the south of Japan, touring a little in the south and Shikoku island before finishing in Osaka. I'm hoping to go as lightweight as I can.
I'm just preparing everything, but I've very undecided about bringing camping gear. When I was in Japan 12 years ago I found it very hard to get good camping spots and ended up staying in local hotels every night, which itself was difficult as online booking wasn't easy in those days. I usually like to stay in local places as I find it better that way to meet other people and practice the language, and so on, and I hate camping in places which are populated, but obviously there may be places where accommodation is difficult and it of course saves lots of money.
So my question for anyone who's done this in the past few years, would it be easy enough to find reasonably priced accommodation between the main cities and towns every night, or is a tent an essential back up for some areas?
Also, I'd appreciate thoughts on the best options for tent there - I have a lightweight tent, but also a hammock and a light tarp and bivvy bag and I'm undecided as to which is the best option.
Many thanks in advance
