The download section of the site is in English, as is the index page. I'm told the Japanese advisory (when you sign up) basically translates to "your password will be e-mailed to the address you provided." Apparently people were abusing BAT's CGI, which led him/them to require registration. The e-mail adress you provide will be your logon ID. You'll be sent an impossible-to-remember password. :-) You can trust BAT ... you won't be SPAMmed. And for the one or two people out there who don't already know, BAT lab clothing is top-quality. All of it is for female characters, Posette, Vicky, and I think a couple of MilGirls items (no Judy stuff yet.) Be advised that most of it is quite sexy, and some items are bondage-oriented. Avoid the site if that stuff offends you, although you won't encounter any explicit images, as I recall. Just cute "pinup" style images. BAT clothing could easily sell for top dollar (or Yen,) but it's still free. Yet again for those who don't know, there's a marvelous neo-witch outfit at BAT, just in time for Halloween!
