The announcement was that Shimizu's debut would be against former KBC Featherweight champion In Kyoo Lee (3-2, 1) [이인규], who won the KBC Featherweight title in 2004 with a win over Moon Sun Jung, as seen in the video below. From the records we can find Lee hasn't fought since that win, though with Korean boxing being a total mess there is a good chance he is more experienced than the numbers suggest.
Shimizu's debut will be 6 round bout set at 58KG's, which is just under 127.9lbs. This would make one assume that Shimizu's future lies at 126lbs going forward and not 130lbs. As a Featherweight he will be a very tall fighter and as seen today he towered over former former world title challenger Satoshi Hosono (32-2-1, 21) [細野 悟].
Video shows Lee's most notable bout to date, and we believe his most recent.
