Breeding sites of the Japanese Murrelet Synthliboramphus wumizusume are restricted to some small islands off Japan, but its breeding behavior and postbreeding dispersal are poorly known. On May 2003, an observation of a chick was reported in the south of Boso Peninsula, southeast Japan. On 16 May 2006, I observed two adults and two putative chicks of the Japanese Murrelet, on the coast of Tateyama City at the south end of Boso peninsula. This site is c. 70 km away from the nearest islands where this species is known to breed.
