Passersby are sure to do a double take when they see the wooden building on the corner of the busy intersection in Kawasaki, 15 minutes walk from Musashi Nakahara Station.

Set back from the road, with potted flowers and small tables out front, it looks at first glance like an outdoor cafe.

From a two-story-high "flying cage" to the right, however, come the squawks, screeches, chirps and coos of an assortment of birds; doves, starlings, magpies, pheasants and quail. Through a window one can see cormorants and ducks swimming in a pool and three stories above, a peregrine falcon swoops from one end of its enclosure to the other.
