From the poster it should be obvious that this show is all about Tanaka. Even without knowing Japanese it's clear they are selling the show on it being his 3rd fight, his first 10 rounder and from just looking at the poster it's clear that this youngster is a big deal. It may seem odd for a poster to be so focused on just one fighter but in this case it makes sense. Tanaka really does have that much expectation on his shoulders.
