A yojijukugo from Pure Land Buddhism, literally 'ten myriad myriad lands', referring to the vast distance to the Western Paradise of Amida Buddha. Used to evoke an unimaginably far-off, ideal realm or eternity.
念仏を唱えれば、十万億土の彼方にある極楽浄土に往生できると信じられている。
It is believed that by chanting the nembutsu, one can be reborn in the Pure Land of Ultimate Bliss, which lies far beyond the ten myriad myriad lands.
