16/04/2024 Onomichi - Osaka (Shinkansen via Okayama, Himeji and Kobe);
18/04/2024 Osaka city centre - Universal Studios (JR Train);
20/04/2024 Osaka city centre - Koyasan (Train/Bus);
21/04/2024 Koyasan - Kyoto (Shinkansen and Train);
24/04/2024 Kyoto - Hakone (Shinkansen/Train/Bus);
26/04/2024 Hakone - Fujiyoshida (Bus);

What can you recommend? Thanks in advance.

Kind regards,
