Myoshin-ji is the largest Zen temple complex in the city and the whole country. With over 46 branch temples, it is a "Buddhist small town", a whole world apart. Only a few temples can be visited, most are closed to the public. Nevertheless, it is worth a visit of the plant.
The most convenient way to reach the temple complex is from the main train station on the JR Sagano Line, getting off at Hanazono Station (4th stop from Central Station)
