Information is available online for the 40th Osaka International Gift Show. OIGS features about 200 exhibitors and anticipates about 50,000 visitors. It's scheduled for late September, 2008.
Let's use this event as the basis for a Kansai/Japan Etsy sellers meet-up. I will probably try to attend on the Thursday. Registration is not required.
Tokyo or Kanto residents may be interested in the Tokyo Show for which there is a visitor registration form online, in English.
