April 27 to May 6 is called the golden week. It will be crowded everywhere in the tourist spots and transportation, accomodations as well. Be prepared.

yes, that's why .. i have to prepare everything. Do you think the JR pass is effective at those itinerary?

thanks.

It seems rushed.

On Day 2 for example, you plan to visit Hiroshima and Miyajima and leave by 4.

The Peace Museum takes quite a bit of time itself (not the type of museum to rush through), and then you'll want to see Peace Park behind it. If you add Hiroshima Castle, Shukkeien Garden, the schools, or any other museums, it can easily fill a day by itself.

Miyajima, too, takes time. First you have to get to the port and then catch a ferry. Itsukushima Shrine is not far from the port, but once again, if you really want to see the island, Miyajima can also take anywhere from a half day to a full day.

Even if you only go to Itsukushima Shrine in Miyajima and the Peace Museum and Peace Park in Hiroshima, it's going to be a whirlwind tour to do all that and be back on a train at/around 4.

that's a very nice suggestion... i was thinking to stay a day in hiroshima, but still in doubted.. but now, you just convinced me... thanks a lot!
