Over the last day or so we've seen more details from the card being released, along with the show's poster.
We now know that Hatanaka will battle against former Japanese title challenger Kenta Matsui (8-7, 1) [松井謙太], who will be fighting for the first time since his December loss to the then Japanese Minimumweight champion Reiya Konishi. This is a big step up in class for the 19 year old, who hasn't really been challenged since his debut back in November 2016, fighting only a combined 10 rounds. Although a step up he should still be favoured to beat Matsui, despite Matsui's 2016 win over Rikito Hatrtori and 2017 upset win over Genki Hanai.
As for Yushi Tanaka his opponent has been named as Jinya Ito (6-3-1, 1) [伊藤仁也]. Tanaka has twice fought for Japanese titles, losing to both Kentaro Masuda and Ryo Akaho, but came up short in both of those title bouts. Since losing to Akaho last year Tanaka has notched up two wins and is one his way to getting another title fight. As for Ito he has scored back to back wins, but has gone 2-3 in his last 5 and certainly looks a less than challenging opponent for Tanaka.
It should be noted that former Japanese Featherweight champion Shota Hayashi (30-7-1, 18) [林翔太] is featured on the poster. He won't actually be in action as his appearance on the card will be a retirement ceremony, as he walks away from active fighting following recent losses to to Kosuke Saka and Mark Magsayo.
