Negoroji Temple in Iwade City in Wakayama Prefecture is a head temple of the Shingi Shingon Buddhism. The Daito pagoda at Negoroji temple was constructed by modeling after the one in Mt. Koya, the headquarters of the Shingon Buddhism. According to the document discovered during the demolition work for renovation, the construction started in 1480, continued for nearly 70 years and completed in 1547. The bullet wound made at the time of the Siege of Negoroji commanded by Toyotomi Hideyoshi can be seen on the surface of the base wood.
