I must admit I simply found it by walking through the streets of Tōkyō, Japan. Yushima Seidō is a temple dedicated to the doctrine of Confucius – a well-known Chinese philosopher.
The temple had different locations in the city, at first in the Ueno park. You can see a giant statue of Confucius within the area.
