As Meijin Kawaguchi, Tatsuya has continuously participated in several world tournaments that followed. He has won 3 world championships in a row. At some point in his career, he has entered the Gunpla battle's Hall of Fame. He has also been a trademark figure in several gunpla events, including the Artistic Gunpla contest and Meijin Cup building contest. Aside from participating in gunpla battles, he's been roaming around gunpla battle scenes to watch and observe different fighters.

Seven years after the 7th World tournament, he presented Yuuma Kousaka with the trophy for the "Artistic Gunpla" building contest. He gains an interest in Team Try Fighters as they are coached by Mr. Ral, the Blue Giant, and is often seen with Lady Kawaguchi, the only known woman to have inherited the title of Meijin Kawaguchi. He later observed Team Try Fighter's battle against Team G-Master and wants both team's Gunpla to blaze on during the heat of the battle. At the Nielsen Labs, he barged in Saga Adou's battle with the Team Try Fighter using his PF-78-3A Gundam Amazing Red Warrior. The battle was later stopped by Allan Adams. He also encouraged Yuuma Kousaka to work harder after his lost to Adou.
