RWC

Hi
Myself and three friends are visiting in October 2019 for the RWC.

We are planning to be in Japan between the 4th Oct and departing 21st.

We are planning to spend 6 days in and around Tokyo then moving onto Yokohama, Shizuoka back to Yokohama.

In the final week we are travelling onto Oita via Kyoto, Osaka, Hiroshima and Fukuoka.

We plan to travel back to Tokyo on Sunday to depart Narita late morning on Monday 21st.

Few questions

Should we buy a two week JRP pass or purchase individual tickets for our trips

Can we catch a Bullet train and see Mt Fuji

Could we get back to Tokyo on the 20th from Fukuoka by train (if so how long is it) or should we fly back

Thanks
Martin
