Harumichi Tatekawa (born 2 December 1989) is a Japanese rugby union player who can play either as a fly-half or centre. He plays for the Kubota Spears in his native country and the Brumbies in the international Super Rugby competition.
Tatekawa started out his professional career in Japan's Top League playing for the Chiba-based Kubota Spears. His impressive record in his homeland saw former Australia national coach Eddie Jones recommend him to Brumbies boss Stephen Larkham. The Brumbies were on the lookout for new talent in the 10/12 area due to an injury to Christian Lealiifano and were happy to snap him up as part of their development plan. Former Wallabies and Spears player Toutai Kefu sang Tatekawa's praises on signing for the Brumbies, saying he was the best Japanese player he'd ever seen.
Tatekawa made his international debut for the Brave Blossoms in an away match against Kazakhstan in April 2012 and to date he has made 20 appearances and scored 36 points including 4 tries.
