JR Pass or Regular tickets for my 4 weeks itinerary in Japan?

Hi there,

1&2.) You do a lot of travel, and the only pass that really would make sense is a 21-day JR Pass (when looking at your timing) and would cover nearly all your travels. Have you considered taking the train back to Osaka instead of the ferry, for even more savings? Be sure to include trips to Nikko, for the best savings.

3.) Sorry, I'm not entirely sure what you're asking here.

Kind regards,
Daniel

Thank you for your answers Daniel- san. I was planning to take the ferry to Osaka, to have a different experience but also because I was thinking to get the 14 day JR pass only, starting on my travel day from Kyoto to Osaka, and it will not work anymore by the day I planing to return from Beppu or Fukuoka to Osaka.
Sorry If the question was not clear. What I meant is, now that you consider to take the 21 day JR Pass instead. I would like to know, which day would you recomend to start using it?, since of course it will not covered the whole trip.
Thanks!

For the best date / optimization.

I'd switch Nikko to day 7, start using the pass on that day and make use of it until you reach Hakone.

There are different budget options (such as local train, bus) from Hakone to Tokyo to save on money.
