When Late Apr 2026

Golden Week in Iwate Prefecture brings with it one of Japan's more unusual and fascinating cultural events, the Osawa Konsei Festival, which is held each year at Osawa Onsen. Taking place on April 29th, this unique ritual combines Shinto tradition with the healing waters of the hot spring.

At the heart of the festival is a sacred object carved from zelkova wood in the shape of a phallus. Far from being crude, this symbol represents fertility, safe childbirth, and vitality, reflecting ancient beliefs about life and renewal. The day begins with a Shinto ritual at 2pm, complete with kagura dance performances and the beat of taiko drums, before rice cakes are scattered among the crowd.

The ceremony then moves to Osawa no Yu, the onsen's famous open-air bath, where the sacred object is ritually washed and floated in the steaming waters. Women seeking blessings for fertility and wellbeing take part in the purification rite, a tradition that has been passed down for generations.

Following the ceremony, the sacred object is returned to its shrine and later carried to Mt. Okubo at the close of Golden Week. With origins dating back to 1971, the festival is deeply rooted in local history while offering visitors a rare glimpse into Japan's traditions.

Getting there

The event takes places approximately 30 minutes by taxi from JR Hanamaki Station, or around 15 minutes driving time from Hanamaki Minami IC on the Tohoku Expressway.

Please note that guests are encouraged to use public transport or carpool due to limited parking.
