Wonder Festival

The Tokyo Wonder Festival (ワンダーフェスティバル^?), or Wonfes (ワンフェス, wanfesu^?) for short, is a semiannual (Feb, Aug) event held in the Makuhari Messe, in Chiba, Japan. The main focus is to display and sell "garage kits", which are sculptures that usually replicate anime and game characters, but also popular mecha/sci-fi characters and creatures such as Kuratas. These models are extremely detail oriented, and many of these sculptures appear in very small quantities due to the amateur nature of their reproduction. Unusually skilled artisans are promoted specifically during the "wonder showcase" (WSC), in which their works are given special attention and limited quantities of their masterpieces are sold for high prices to avid collectors. It also showcases future releases by major toy companies.
