I know how you feel. I'm waiting for a Birkin, but I had to get something that was leather. I just got a Mini Ulysee agenda. I got it with plain paper (I think that's all that's available on the Mini anyway) just to keep in my bag to write little notes or whatever. I don't know about the boutiques in Japan, but I live about three hours away from the Northern Virginia Hermes, and they will ship out small pieces like I got, so you might be able to call a boutique and get them to ship to you.
By the way, is your husband in the Navy? Mine in, and we're in Virginia Beach.
Here's a picture of the agenda, and the Pocket Square I just got.
