Kongoji Zen Temple offers an authentic and budget-friendly temple stay at just 6,000 yen per night. The best times to visit are in the spring and fall, as summer can be too hot and winter quite cold—something I experienced firsthand during a freezing stay in mid-March, which felt like real Zen training! The monk doesn't speak English, but his wife does, and they provide English guides for everything, making it accessible for foreign visitors. If you're looking for a genuine Zen temple experience away from touristy spots, this is a great choice. Plus, the friendly temple cat who loves being petted adds a special touch to the peaceful atmosphere.
