Akihiko, as well as his Yakuza subordinates, were targeted by Hawkeye who considered that they did not deserve to survive the Decimation. Barton decided to eliminate the rest of the criminals by his own, and hunted Akihiko down to Japan. Eventually, Akihiko's hideout in Tokyo was attacked by Barton, who had hunted down Akihiko to take him down. Despite his most trusted men's best efforts, his henchmen were all killed by the Barton, who then challenged Akihiko to a swordfight.
Though he fought his best, Akihiko was ultimately no match for Barton, who fatally injured Akihiko by slashing his throat. With his dying breath, Akihiko asked Barton to help him before he executed him by stabbing Akihiko with his sword backward, ending with the life of the Yakuza boss.
