The 36 year old Sakamoto, who turned professional back in 2007, announced that his opponent for the bout would be Koki Koshikawa (6-1, 4) [越川孝紀], who turned professional with high expectations but has so far failed to deliver.
Sakamoto stated the bout would be the final one of his career, and comes after a notable break from action, with the Kadoebi man last fighting in November 2017. That bout saw him lose in a bout to unify the Japanese and Japanese "interim" Welterweight titles, with Toshio Arikawa stopping him in 5 rounds.
Whilst not well known outside of Japan Sakamoto has had a pretty interesting career at hime, fighting a domestic who's who of the Light Welterweight and Welterweight diviison. He has shared the ring with Yasuhiro Okawa, Moon Hyon Yun, Cobra Suwa, Nobuyuki Shindo, Toshio Arikawa and Makoto Kawasaki.
As an amateur Koshikawa shined before signing with the Celes gym. Sadly his professional career which began back in 2014, has been a frustrating one. He looked to be on the fast track before losing in 2015 to Koshinmaru Saito. Following that loss he would be away from the ring for over 2 years before returning in August, and beating 2 over-matched Thai foes.
Also set to be on this card are Japanese ranked fighters Yusuke Konno (12-4, 6) [今野裕介], Cristiano Aoqui (12-7-2, 8) and Tsuyoshi Sato (6-1-1, 2) [佐藤剛], though none of them have had confirmed opponents announce for the card as of yet.
