This is a commemorative challenge coin from the Misawa Air Base Air Festival and the "MISAWA WEAPONS FEST" event. Brand: wakas. The design features a skull motif, and the reverse side design is an art style inspired by vaporwave and synthwave, drawing from 1980s computer graphics and music. I think it's an interesting item in terms of design. For those interested in the U.S. military, military items, and collectors, please consider this item.
