Went 14 Days in early April with my wife. Mandatory route: Tokio -> Kyoto -> Osaka.
Really impressive country. Excellent food, organized infrastructure and very respectful, law-abiding citizens.
Each city had its own vibe: Tokio was fast, futuristic and modern,
Kyoto was spiritual, calm and traditional
Osaka felt lively, energetic and a bit more chaotic in a good way.
I hope I can visit sometime agian.
