By contrast, portrayals of Acala (Fudō) in Japan tend to conform to the description given in the "Amoghapāśakalparāja Sūtra" and the "Mahāvairocana Tantra": holding a lasso and a sword while sitting or standing on a rock (盤石座, "banjakuza") or a pile of hewn stones (瑟瑟座, "shitsushitsuza"), with his braided hair hanging from the left of his head. He may also be depicted with a lotus flower - a symbol of enlightenment - on his head (頂蓮, "chōren"). Unlike the South Asian Acala (whose posture conveys movement and dynamism), the Japanese Fudō sits or stands erect, suggesting motionlessness and rigidity. The sword he wields may or may not be flaming and is sometimes described generically as a or , which is descriptive of the fact that the sword's pommel is in the shape of the talon-like vajra (金剛杵, "kongō-sho"). It may also be referred to as a . In some cases, he is seen holding the "Kurikara sword" (倶利伽羅剣, "Kurikara-ken"), a sword with the dragon ("nāga") king Kurikara (倶利伽羅; Sanskrit: "Kulikāla-rāja" or "Kṛkāla-rāja") coiled around it. The flaming nimbus or halo behind Acala is known in Japanese as the "Garuda flame" (迦楼羅炎, "karura-en"), after the mythical fire-breathing bird from Indian mythology.
