Prior to joining the Toryumon system, Araken spent some time in the FMW system.
1998: Debuts as a 2nd term student.
1999: Comes to Japan with Toryumon as a heel. Feuds with fellow heel Sumo Fuji
2000: To rid what is left of his heel past, and reinvent himself he starts the Keni'chiro Arai Denaoshi Saishugyou series. He won the first 24 matches before losing the last. Still, he turned that success into a title win, capturing the NWA Welterweight title.
2001: Competes as a member of Seikigun
2002: Debuts the Hanshin Tiger Suplex, named after the Hanshin Tigers baseball team.
2003: Joins Shin M2K. At the end of the year, defeats leader Masaaki Mochizuki to bring the unit to an end.
2004: Reconciles with Mochizuki to join Final M2K. Runs on foot from the Odaiba Mainichi Pro Wrestling tent to Differ Ariake while the show is broadcasting live on PPV. Makes it in time for his entry into an elimination match. Loses despite the effort. Begins appearing as a masked character "Heno Heno Kamen" to make life miserable for Touru Owashi. Even though he wore the exact same ring costume and did the exact same offense, Owashi never figured out who it was and actually lost the feud.
2005: Acts as a mentor to Tozawa after his debut.
2006: With Final M2K unraveling, Tozawa and Tozawajuku begin to actively recruit him. They went as far as to bring his mother out to convince him.
2007: Joins up with Tozawajuku, attacking Mochi. Mochi was not bothered by the attack and continued talking through it .... Experienced a career renaissance through his tag team with Taku Iwasa.

AraIwa continued their success into 2008 when they won the Open the Twin Gate. Araken strengthened Tozawajuku, recruiting Shinobu as an exchange student and El Generico as an international transfer.
