Siam Shade (stylized as SIAM SHADE) is a five-piece Japanese rock band, which broke onto the visual kei scene alongside a multitude of other artists in the early 1990s. They enjoyed a decade of relative popularity before disbanding in early 2002. The members have reunited several times since 2007 for one-off concerts and a short tour. Outside Japan, Siam Shade is best known for "1/3 no Junjou na Kanjou", one of the many ending themes of the Rurouni Kenshin anime.
