Hey guys! I'll be going to Japan this coming April for a 6-day trip, will be crashing at Tokyo Backpackers in Minami-senju. There are several things I'd like clarified:

1. I'm planning on visiting Evangelion World at Fuji-Q; do I have to pay the 5000 yen entry fee into Fuji-Q, or Eva World is a separate entity from the theme park?

2. I heard Kanda's the place to go if one is a book lover, being that there are lots of second-hand bookstores there. Is this true?

3. Is it feasible, both finance-wise and time-wise, within a 6-day trip, to go to Yamagata (somewhere around the Yama-dera temple) and back? I'd like to visit my host family from my previous Japan exchange programme if possible.

4. It'd be spring during April. I'm prone to hayfever; how bad is the air during the season? I'd hate to walk around with a runny nose and a pocket full of wet tissues... It's best if I can prepare some medication beforehand.

I'll think of some more questions while I'm at it. Answers are appreciated!
