Japan is globally popular for its shrine culture and houses approximately 80,000 shrines. The most important among all is the Ise Grand Shrine. It is one of the most expensive temples in Japan due to its architectural grandeur. To maintain the Shinto traditions dating back to the 8th century, this temple is rebuilt every 20 years. And that comes with a million-dollar price tag. Unless you are a member of the royal family, you are forbidden to enter the hallowed halls of this ancient Japanese representation.
