The last structure I expected to see in Japan

When I think of aqueducts, I imagine Italy, but beyond the main buildings in the Nanzen-ji Temple grounds, was a red brick aqueduct. A sign reassured visitors the crack in the brick was not structurally dangerous so I stepped underneath to climb to the top.

From above, water moved along the top to confirm that the structure was still in use.
