Today no tourists visit this temple for a prayer, but to see curiously its deceitful architecture deviced by the then most powerful shogun in Kaga (old name of Kanazawa) for his own regime survival. It looks just a normal 2 stories temple, but actually 29 number of staircases are built beneath the floor, behind the wall, and everywhere else, which connect total 7 layers of floors in this temple. (Back then, building any architecture of more than 3 floors was prohibited by law). It is also said that the water well located at the center of this temple is a hidden path to escape to Kanazawa castle, with a long tunnel built under the ground. None of these are fiction, it is a historic truth!:0 A 1000 yen entrance fee sounds a bit costly and you need to book for the entrance beforehand, but instead you get a group tour (around 15 people) with a dedicated guideperson, which is arranged every 30 minutes. The guided tour is around 40-50 minutes, no photograph is allowed inside. Not sure if the guide can also arrange English tour.
There is not much else to see around this temple area, except Nishi-Chaya district, literally meaning West-Teahouse, where geisha used to entertain their guests in a restaurant.(Now you will not see any of them) 10 minute walking distance from Ninja temple. More
