Maisaka lay about six miles down the highway from Hamamatsu, at the point where Lake Hamana and the ocean are joined by a narrow stretch of water.
In early times Lake Hamana was isolated from the sea, but in 1499 the land between them was washed away in an earthquake and tidal wave. Because of this the mouth of the lake acquired the name Imagiri, which means literally "now broken," and women travelers who were betrothed regarded this place as inauspicious ,for their marriage prospects. It is said that they regularly walked all the way around the north shore of the lake rather than cross Imagiri by boat, as was the usual procedure.
Hiroshige's picture bears the legend "True Picture of Imagiri," but in fact the mountain in the center is Hiroshige's invention.
