I just did the Shimanami Kaido, the most famous bike route in Japan, yesterday and used a variation of this. It was designed for cyclists as the bridge entry ramps have low inclines of ~3%, and there are minimal situations where you have to stop. The visual indicators are clear enough that you can go without your electronics for navigation, too, and the pavement is smooth. The route is from Onomichi in Hiroshima prefecture to Imabari in Ehime prefecture. It consists of 6 islands and 7 bridges, but I took a ferry for one of those bridges. The weather was chilly but I didn’t want to bring my jacket since I expected to sweat from the ~70km ride. The luggage delivery cost was 2,200yen per item regardless of size. The drop-off time is 8am-10am and pickup time is 6pm-10pm. The ride should only take 4 hours but I took my time, started at noon, took many sightseeing/refreshments, and did 90km in total with detours knowing there’s no point in arriving early. You can elect your drop off location so I picked the onsen hot spring. Arrived at 7pm, confirmed my luggage was there and used the hot spring to recover from the bike ride.
