Koido

Koido [泍來個; こいど] is a city located in western Kawara Prefecture. As of 2020, it has a population of roughly 20,000.
Koido is located in the lowest slopes of the Iwara Hills, just below Mount Samuhara. The city is known primarily for its cold winters, which feature heavy snowfall and subzero temperatures. Hillwalking and hiking is popular around the western mountainous outskirts, and many frozen waterfalls can be found in winter which are suitable for ice climbing. Camping is also popular, with caravan parks and log cabins in the area available for use, along with several guesthouses offering nature retreats.
Koido is also known for its iconic Aigai Festival, or 'Festival of Love', during which couples are encouraged to parade through the streets in outlandish costumes or on floats. Older/elderly couples, usually married ones, will head the parade and receive the most attention, while younger lovebirds will bring up the rear. This festival pays tribute to a legendary tragic love affair that took place in the area over 500 years ago; the story of Princess Yu no Ishi and a Summui prince named Garō. They were forbidden from marrying due to their different bloodlines, but would meet in secret on the slopes of Mount Samuhara.
