Last summer I rode route 1 from the Tokyo area to my in-laws relatively near Shizuoka station (nishi-aizu): Day 1 Tokyo to Odawara, Day 2 to Nishi-Yaizu. Being my first bike trip it was fun but could have been more enjoyable. A more experienced cyclist recommended using this forum to find a better route. Adding a day or two is ok as I think I'd like to see parts of Izu. Any recommendations or tips.
