Couple of things I would second from previous recommendations, take a shuttle to Yokohama and ride down either to Miura or cut across to Kamakura (a savage climb but only around 10 minutes- PM me if you want the route)... also I would pick up a SIM from the airport. If I was doing the trip I would live on conbini food. I lived up in the Japan Alps for 8 years, so I know the high stuff, but also did 9 months in Yokohama from Sept 2015, so I also know the urban cycling feel. Going through towns you will stop every 50 meters for a stop light, but in the country riding is lush. Do check out Cycling through Japan on NHK World, that could give you some great tips for local routes. Good luck! October weather is great...
You think I could get away with this as a vegan / vegetarian? It is something I considered and obviously doing so would save a lot of time + weight... But I am a Worrier so I like the idea of having some self sufficiency...
