Definitely ask your host about housing. If you're at a university they might have special short term researcher housing or dorms which are fairly inexpensive.

They're making you guys sweat this year! At least EAPSI is a fairly fast turn around (compared to GRF or GROW).

I accepted both awards. As long as the awards don't overlap time wise NSF and JSPS are ok with awarding both. I.e. I spent this summer in Japan for EAPSI and going back tomorrow for GROW for 8 months. Message me your email or Facebook. I'll be traveling the next couple of days and probably won't check this site too often.

I applied to both EAPSI and GROW (Japan) last year and was awarded both. My GROW project is an extension of the EAPSI project so the two proposals are similar. For the budget just create a brief table stating what the funds will be used for (ie airfare, moving expenses, baggage fees, some research materials, etc). Also make up a separate budget for the living allowance that includes things like rent, food, insurance, etc. If you have any other questions I'll be happy to try to answer them.
