Daikoji (Sadowara-cho, Miyazaki City, Miyazaki Prefecture) is a temple of the Myoshinji school of the Soto sect. It was founded in 1335 by the Zen priest Gakuo Choho with the patronage of the 4th provincial lord, Tajima Sukefusa. Then in the Edo period (1603-1868), the temple was protected by the domain lords, the Shimazu clan, being enfeoffed with the territory of 75 koku of rice, and reached the height of prosperity.

It was during this period when the renowned Zen monk Kogetsu, who was born in the local village of Sadowara, became the 42nd chief priest of the temple and was actively engaged in missionary work for the local commoners. He is called the restorer of Daikoji Temple.

The statue of Monju Bosatsu sitting atop a roaring lion and guarded by four warriors was carved by a Buddhist sculptor Koshun in 1348. The statue is designated as a national Important Cultural Property. The temple possesses a lot of historic documents collected under the policy of the chief priest Kogetsu. They are now being used as precious data of the history.
