It is a magical place.
The main hall contains a big Buddha sitting on a lotus flower surrounding 1001 (!) standing golden Kannons (Goddess of Mercy) about human height made from cypress wood almost 1000 years ago. It's a shining army! The statues have 21 pairs of arms which symbolizes 1000 arms. There are different objects in the statues' hands. The statues have many faces (there are 11 small heads attached to the Main head). There are many other statues: G-d of Wind, G-d of Thunder, Heavenly Kings, etc. Some are playing musical instruments, some have wings, some have horse head on their head, some have fin-like brows, etc.
Unfortunately, you cannot take a picture there.
There is also a nice small garden outside.
Allow at least an hour.
