Fudo Myoo, Kanjizai-ji Temple, Shikoku, Japan

Ayra Acalanatha is known as Fudo Myoo in Japan.  He is greatly venerated in Shingon Buddhism, and several temples in Shikoku are dedicated to Fudo Myoo.  As a wisdom deity of the first order, Ayra Acalanatha is the friend of all Dharma fools:

Acala Vidyârâja is one of the Vidyârâjas (Myôôs) class of
deities, and a very wrathful deity. He is portrayed holding a
sword in his right hand and a coiled rope in his left hand. With
this sword of wisdom, Acala cuts through deluded and ignorant
minds and with the rope he binds those who are ruled by their
violent passions and emotions. He leads them onto the correct
path of self control. Acala is also portrayed surrounded by
flames, flames which consume the evil and the defilements of
this world. He sits on a flat rock which symbolizes the
unshakeable peace and bliss which he bestows to the minds and
the bodies of his devotees.

He is said to be of “the markless Dharmakaya, identical with all-encompassing space itself. Thus he has no dwelling. His only dwelling is in the minds and thoughts of living beings.”

Acalanatha’s Mantra

Nômaku sanmanda bazaradan senda makaroshada sowataya un
tarata kanman. (Jpn.)

Namah samanta-vajrânâm canda mahârosana sphotaya hûm trat
hâm mâm (Skt.)

Homage to the all-pervading Vajras! O Violent One of great
wrath! Destroy! hûm trat hâm mâm
