Can I just die of jealousy? We're "supposed" to go to Japan next year and the only thing I want to do is vanish near Asakusabashi Station in Tokyo. I hope your husband comes home safely, and that you have a great time shopping for with him. 
The books are so much cheaper in Japan. I was really lucky to buy them in Honolulu at the Japanese price. I guess Hawaii is heaven, huh? LOL
You used to be able to order them off Amazon.com.jp and not pay an arm and a leg for shipping, but they've changed their policy and now shipping is like $30. 
I would really like to go to Tokyo as well. We had a 3 hour layover there on the way to Okinawa, but were not able to leave base. I have a severe phobia of flying so it prevents me from really being able to take advantage of the discounted flying rates from the island. It takes everything I have (drugs help to :P) to have been able to make it from England (where we were stationed previously) to here lol.
If we take the same flying route home as we did here, we plan on spending a week in Tokyo. I would really love to tour the bead factories there and my daughter is really into Anime so she would love it as well.
Another good place for Japanese beading books is eBay. There is a seller that offers a wide variety of Japanese beading books for pretty close to the Japanese price. And what makes it even better is he offers free world wide shipping. Just type in Japanese bead book and click on the "see additional buy it now" link at the bottom of the page. I sort by "prices lowest + shipping".
