Oike no Hyakuhatto, handed down through generations in the Oike district of Yawata, Chikuma City, is a traditional event in which straw towers are lit to honor Komatsu-hime.
About Oike no Hyakuhatto
Oike no Hyakuhatto is an event passed down in the Oike district of Yawata, Chikuma City, in which straw towers are lit to honor Komatsu-hime.
Against the backdrop of the history of Oikeshinden Village and Komatsu-hime, 108 lights are arranged along the old road leading to Ipponmatsu Pass.
Today, local children also take part in gathering straw and building towers, with the Oike District Youth Association taking the lead.
It was designated a Chikuma City Intangible Folk Cultural Property in Heisei 27 April 1.
Festival highlights
Highlights include straw towers set about 2 meters apart along the old road, with each one lit in turn.
The final light among the 108 is used to set alight a larger tower, creating a view of towers in different sizes lined up together.
As dusk gives way to night, the flames appear against the nightscape around Obasute—another distinctive feature of the event.
Because it is dangerous near the fire, visitors are also advised to watch from Oike Community Center.

The towers are lined up along the main road and lit in sequence, starting from the top.
Finally, a tower larger than the others is also set alight, and the 108 lights honor Komatsu-hime.
Preparations through to the lighting are carried out locally, with the Oike District Youth Association taking the lead.

Origins and History of Oike no Hyakuhatto
Oikeshinden Village is said to have been land granted to Komatsu-hime as a dowry in Tensho 14 (1586; accounts vary).
Komatsu-hime died suddenly in Genna 6 (1620). After Oikeshinden Village became the territory of Daieiji Temple following Nobuyuki Sanada’s transfer to Matsushiro in Genna 8 (1622), lights of remembrance are said to have begun around the following year.
Since then, the event has been carried on as a tradition of lighting 108 lights along the main road at dusk on the lunar-calendar August 16, and was designated a Chikuma City Intangible Folk Cultural Property in Heisei 27 (2015).
