The volitional form of Group II (ichidan) and Group III (irregular) verbs are formed with よう (-yō) instead of う (-u).

In traditional Japanese grammar, this is a 助動詞 (jodōshi, “auxiliary verb”), with the sole form う (u) as the 終止形 (shūshikei, “terminal form”) and the 連体形 (rentaikei, “adnominal form”). Morphologically, this is an uninflecting inflectional suffix whose proper shape is /oː/ (-ō), attaching to the stem of consonant-stem verbs.
