This is the Osu Kannon temple in the central district of Nagoya.
To the east of the temple are the covered shopping streets of Osu (click full screen button on the linked page for best results).
Next weekend on the 14th and 15th, the temple will host the Osu Daido-chonin Festival, a yearly festival that is famous for it's street performances.
Monday the 9th was a national holiday, taiku no hi (physical activity/education day), and both the shopping streets and the temple alike were busy.
The temple and shopping streets of Osu also host the Nagoya St. Patrick's day parade each March, the first of which was held two years ago when yours truly took to the streets as the famous saint (who I had always thought was Welsh, but some say Scottish and some just don't say....).
