On April 24th Tokyo will be hosting the Kaiju World Festival. The official festival site hosts many kaiju kits/figures (as you'd expect) from the likes of Participating Dealers: Asai Zokei, T-Facto, Monster Maker・２８, Image, GOWROW, Eaglecraft, KudaFuromi, Zokei Kohbo Kitra, X-plus, Yume Kobo Highlight, Beranedon, TANAKAKENICHI, and Studio Headmaster. The prices and availability are listed for most (some being listed as Sold Out).
Godzilla and Gamera will most definitely be in great numbers when the festival kicks off. I've added a few of my favorite kits that are listed on the site.
Access to the event is Free, so if you're in Japan and like more information on the event, please go to the official festival site (hopefully you can translate it from Japanese) and view all the offerings.
