Help to decide about the pass.

Hi Manju,

I think a 7 day Rail Pass can be well worth it if you use it from day 3-9.
Here is a little breakdown of the costs without the JR-Pass.

Kyoto --> Hiroshima ¥ 10,790
Hiroshima --> Tokyo ¥ 18,050
Tokyo --> back to Osaka ¥ 13,750

For a total of ¥ 42,590 the 7 day JRPass is ¥ 28,300 saving you ¥ 14,290

For your Hotel, it is just in front of exit nr 8 for TANIMACHIYONCHOME station.
The easiest way to reach this is to take the Osaka Loop Line to MORINOMIYA
and transfer here to the metro Chuo Line to Tanimachi-yonchome.

Hope this helps.
