Tatsuta-age is a type of fried chicken or fish where ingredients like chicken or fish are seasoned with soy sauce, mirin, ginger, etc., then coated in potato starch or wheat flour and deep-fried. The name originates from the Tatsuta River flowing through Nara Prefecture. It is said to be named because the reddish-brown parts of the fried ingredients and the white potato starch coating floating on the surface resemble maple leaves floating on the water, reminiscent of the river's famous autumn foliage.
