The actions of 0-Kashiwara operators on the Uq'(G2(1))-crystal Bl in [Yamane S., J. Algebra 210 (1998), 440-486] are made explicit by using a similarity technique from that of a Uq'(D4(3))-crystal. It is shown that {Bl}l ≥ 1 forms a coherent family of perfect crystals.

Key words: combinatorial representation theory; quantum affine algebra; crystal bases.
