Hi, I know its hard to deal with these little "bugs" at 1st. I will be going through a lot of them. I am going to try and finish up the Japanese Pack, at least up to 1.3.7 version of zen-cart this Friday/Saturday. It might be a chore to get it all worked out by then, but I am meeting with a customer on Saturday, and its my goal to have the pack installed by then. I am also creating a write up for the install as I go through it. I will try to address as many issues as I can.
For the name, it can depend on your database limit.
Make sure to always enter information into the site when the cart is in Japanese. That might fix things for you.
As for the yen symbol, I would just use "yen" for now, as that is accepted practice in Japan, I know this isn't a great fix, but it should work for now.
I will post back when I have the pack up and going. Also Mr. Seiji Matusumoto is going to help in creating the Japanese pack for 1.3.8. He works at a college here in Japan dealing with open source projects...what college I can't remember off the top of my head, but he is a great guy and his work is top notch.
Regards,
