You are so lucky to live in Japan, not just for the hobby shops (Food, culture, etc.) but the easy access of Macross & Other Anime related items, such a pain in the rear to get stuff here in the states these days (short of online) and when you do find them they sure seem over priced and a limited selection. When I lived in LA there were a handful of good shops, now living in KS my nearest Anime of any kind store is in Missouri...lame!!
So when you walk into that Hobby shop Monday, have a big smile and remember its good to be in Japan!!
