The bout, which will be the headlined bout of an upcoming Osaka Teiken card, will see Tatsuyoshi battle against Indonesian fighter Rio Nainggolan (2-2, 2)* and see the Japanese youngster graduate from the 4 round bouts that he has been cutting his teeth in so far.
It also seems that a notable supporting bout on this card will be a 6 rounder and see the debut of former amateur stand out Kazuaki Miyamoto (0-0) [宮本 知彰], who recently passed his B license pro-test.
Interestingly the announcement of the bout, and show, came with two other bits of news in regards to Osaka Teiken.
One of those bits of news is that Sho Nakazawa (8-1, 4) [中澤 奨], has decided to have a change of scenery and has been "loaned" to the Teiken gym in Tokyo, for 1 year. For Nakazawa the plan seems to be to try and improve by spending time in the same gym as some of the top fighters in Japan, before a possible full time move to Tokyo in the near future.
The other bit of news is that the once touted Tatsuya Ikemizu (13-2, 6) [池水 達也] has left the Osaka Teiken gym and has joined the Ioka Gym, following his second loss in 3 bouts.
*Also reported as 5-2 (1)
