The Shogi-do hall holds a 1.2-meter keyaki-wood shogi piece honoring legendary shogi master Oyama Yasuharu.

The current main hall was rebuilt in 1993 using all-keyaki wood construction after the original was destroyed in WWII air raids, preserving over 1,000 years of shrine history.

Its Fujizuka is Tokyo's oldest miniature Mount Fuji that still stands in its original location, dating back to the Edo period.

Founded in 860 CE after countless white doves suddenly appeared in mysterious clouds and flew westward, leading locals to build a shrine and name it 'Hatomori' (Dove Forest).
