国粋主義
During the Meiji period (1868–1912) Japan abandoned its feudal system and opened up to Western modernism. Shinto became the state religion, and Buddhism was coerced to adapt to the new regime. Rinzai and Sōtō Zen chose to adapt, with embarrassing consequences when Japanese nationalism was endorsed by the Zen institutions. War endeavours against Russia, China and finally during the Pacific War were supported by the Zen establishment.
