The tough and exciting Arakawa, who is of course best known for his loss to Omar Figueroa in 2013, is enjoying a small Indian summer in terms of his career with back-to-back wins over Yuya Sugizaki and Kota Tokunaga, with both of those wins coming after a 1-4 run. The win over Sugizaki made Arakawa the mandatory challenger to the Japanese title and he made the most of that opportunity by out working Tokunaga back in April. That win saw Arakawa become a 2-time Japanese champion, reclaiming the title he held from 2010-1011.
Aged 34 it's unlikely Arakawa has long left in his career, especially given the nature of some of his fights but he'll be a hard man to rip the title away from.
The challenger is a lot less well known with Tsukada having never fought at title level before. He does hold some notable wins, including a victory last year over Kazuhiro Nishitani, but was beaten last time out by Ribo Takahata,who stoppedhim in 2 rounds to give him his 4th stoppage loss.
Although less distinguished the challenger is the younger man at 27 years old and knows this will be the opportunity of a life time with another title shot being very unlikely.
Although the under-card is unknown we know this bout will take place at the Korakuen Hall and it's thought that the bout may be streamed live over the boxingraise service, though that's yet to be confirmed.
