Omika Jinja Shrine

Located in Omika, Hitachi City, Ibaraki, Omika Jinja is an old shrine said to have been founded in the first year of the imperial calendar. Its enshrined deities are Takehazuchi no Mikoto, a god of weaving, and Mikaboshi Kakaseo, a god of the stars. It is a power spot that carries the world of myth into the present.

The entire rocky hill on which the main hall stands is called Shukukonseki, a Cambrian stratum some 500 million years old, said to be among the oldest in Japan. Myth tells that Takehazuchi no Mikoto sealed the star god Kakaseo, who had resisted the martial gods, within this Shukukonseki rock.

Highlights

• The Shukukonseki stratum, around 500 million years old, where you can touch a rock face that records the memory of the ancient earth
• A rocky hill with chain holds, which you climb for about five minutes in a mini-climbing mood to reach and worship at the main hall set upon the rock
• A grove designated a Natural Monument by Hitachi City, the rich forest enveloping the precinct being a sight in itself

Practical Travel Notes

• Recommended seasons: In fresh green and autumn color, the contrast of rocky hill and forest stands out beautifully. Since the rock climb depends on weather, a sunny day is best

• Time needed: about 30 minutes to an hour including the rock-climb worship. Allow a little more if you want to explore the forest slowly
• Nearby spots: Izumi Jinja, with its clear spring water, is close by and makes a standard pairing. It also combines well with sightseeing in central Hitachi or along the coast

A Quick Tip

The rock climb to the main hall has chain holds and can be slippery, so wear comfortable shoes. Take great care underfoot on rainy days or after rain. Pairing it with nearby Izumi Jinja is the standard course.
