As evening falls, a floating bridge (funabashi) extends across the Jinzu River. Also known as pontoon bridges or boat bridges, floating bridges were not uncommon in Edo-period Japan. Less expensive than a constructed bridge and more convenient than a ferry, floating bridges were composed of a series of planks laid across a line of attached boats. As the river's current sways the bridge toward the left edge of the design, Hiroshige conveys the movement one could expect at these floating crossings. Today, the former Etchu Province belongs to Toyama Prefecture.
