Japan in April? Looking for route advice!

Hey!

I’m planning a last-minute dream trip to Japan in early April this year. I’m debating between a route from Kyoto – Tokyo, or Hiroshima – Kyoto, but am concerned about road closures due to snow. The Kyoto – Tokyo route seems incredible, but looking at web cams it appears there’s still a bit of snow at higher elevations.

I’m hoping to avoid bringing a tent so will be staying in hotels/ryokans most nights, and am comfortable with long days in the saddle.

I’ll have ~10 days on the bike before meeting up with a friend in Tokyo.

Any suggestions between these two routes, or modifications you think I should make? Any other routes I’m not considering? Would really appreciate any advice you all might have.

Thank you!!
