At the time of selecting GW, already failed over half.
In GW should go to minor city/town fr NRT.

Understood where Tokyo and Osaka/Kyoto are?

i'm not after GW, ust plan to sightseeng japan for the first time

The 11th of May is far too busy - there's no way you can see all of those places in one day.

There isn't really a need to go to Osaka at all. IF you are only doing one day there, do it as a day trip from Kyoto. Saves you 30 mins of travel on your first day.

-or-

Spend a few days in Tokyo, then do your itinerary, then last few days in Tokyo again.
