Osaki Hachiman-gu was established by the Date family to enshrine their guardian deity of his castle on 1607.
It has a flamboyant black and gold exterior that beautifully merges with its interior-- especially the 55 brightly colored, hand-painted flowers on its ceiling.
On January 14th, the shrine holds its annual Dontosai Matsuri, where thousands of scantily clad pilgrims parade to the shrine.
Osaki Hachiman Shrine is near Kashima Shrine and Ryuhoji.
From JR Sendai Station, you can access the shrine via bus no. 10 or 15, then alight at Hachimangu-mae.
The shrine is open all year round with no entrance fee charges.
