On 10 September 2007, YKK (owner of YKK AP SC) and Hokuriku Electric Power Company (owner of ALO's Hokuriku), agreed with merging their clubs to aim promotion to the J.League in response of eager request by the TPFA.

On 7 December 2024, Kataller Toyama secure promotion to J2 League after draw 2-2 against Matsumoto Yamaga and ended 10 years in third tier.

The word "kataller" is a portmanteau of the phrase katare (勝たれ) which in Toyama dialect means "to win", and the French aller, "to go".

The phrase is also intended to be a pun of Italian cantare, "to sing", and of native Japanese katare (語れ), "to talk" (written with a different kanji character).
