Garan is one of the most important and central temple complexes in Koyasan (Mount Koya). As such, it has multiple sacred buildings including the main halls, a bell tower, a lecture hall, scripture storage, halls dedicated to a variety of deities and notably, several large pagodas.

The Konpon Daito Pagoda stands 45 metres in height and houses a state of the Dainichi Nyorai or ‘Cosmic Buddha’, the principal Buddha in Shingon Buddhism. The large number of buildings including pagodas within the temple boundary makes Garan highly-photogenic and popular with visitors and nearby Kongobu-ji Temple.
