On the scales today both men made weight and both looked relaxed and calm for what they will both know is a huge opportunity.
For Naito, who is dipping his toes into the Lightweight division, this is a huge opportunity to score a win over a man known on both sides of the Atlantic. Arakawa may not bee a top level contender but he is known in the US and Europe for his memorable war with Omar Figueroa and a win over the "Baby faced Sniper" would boost Naito's profile significantly.
As for Arakawa he's been struggling for form recently with losses to with 4 losses in his last 6, including defeats to Daniel Estrada, Figueroa, Jorge Linares and Yoshitaka Kato. He'll know that a win over the fast rising and much younger Naito would allow him to begin to rebuild his career which is now better known for the fact he's tough than anything else.
We'll not pretend this is an elite tier match up but domestically things really don't get much better.
