Earlier this week Ohashi revealed the poster for the show which features only the Inoue brothers, at least at the moment, along with the WBO world title, the date of the show and the name of the card, "Boxing FES 9.4", building on the Boxing FES brand that began back in 2014.
The poster is certainly lacking in terms of visiting fighters, with neither Petchbarngborn or Saludar being featured, but more telling is the lack of Shimizu on the poster. This may mean that the poster will go through a revision closer to the fight date with an update release closer to the show, or it could mean that the rest of the card has a secondary poster, something Ohashi have done in the past for notable shows.
It's clear from the poster that the focus will be the Inoue brothers but with talk of the card also featuring Koki Inoue (4-0, 3) [浩樹井上] it would seem bizarre for them not to push both the "Inoue Trio" and the debut of Shimizu when it comes to the final design of the fight poster, or an alternative design of the poster.
