The Hitachinokuni Sosha-gu Reitaisai, widely known as the Ishioka Festival and counted among the three great festivals of the Kanto region, takes place over four days on September 15 (Tuesday), 19 (Saturday), 20 (Sunday), and 21 (Monday, a public holiday), 2026.
On September 15, the Reisai, the most important Shinto rite of the festival, is held at the main hall of Hitachinokuni Sosha-gu. This day involves religious rites only, with no public sightseeing events.
About the Hitachinokuni Sosha-gu Reitaisai
Known locally as the Ishioka Festival, the Hitachinokuni Sosha-gu Reitaisai is designated an intangible folk cultural property and has been passed down for more than 300 years since the Edo period. It unfolds through the historic old town of Ishioka, home to the ruins of the ancient provincial capital and distinctive signboard-style (kanban-kenchiku) storefronts. A grand mikoshi decorated with a 16-petal chrysanthemum crest, 12 dashi floats playing Ishioka-bayashi music, and 32 horo-jishi lion dance floats parade energetically through the streets. Held by parish residents to pray for a good harvest, good health, and traffic safety, the festival draws more than 500,000 visitors every year, with last year's 2025 festival drawing over 530,000 visitors across three days.
Hitachinokuni Sosha-gu

Hitachinokuni Sosha-gu is a shrine in Ishioka City, Ibaraki, offering views of both Mount Tsukuba and Lake Kasumigaura. About 1,300 years ago, this area was home to the kokufu, the provincial capital of Hitachi Province, roughly equivalent to today's prefectural capital. Large-scale excavations in recent years identified the site of the kokuga, the center of the provincial government office, and the area was designated a national historic site as the Hitachi Kokufu Ruins in 2010. Hitachinokuni Sosha-gu was founded next to the kokuga as a sosha, a shrine that gathers deities enshrined across the province in one place near the government office. Fifty-five such sosha shrines have been confirmed nationwide.
This Year's Highlights

This year's toban, the town responsible for hosting the festival, is Morikicho. During the Reitaisai, 15 of Sosha-gu's 36 parish towns take turns each year serving as the toban town, building the okariya, a temporary shrine that welcomes the deity. This year's toban town, Morikicho, is the first of the 15 towns in the rotation.
In front of the okariya, the grand mikoshi gathers together with more than 30 horo-jishi lion dance floats, 12 dashi floats, and the sasara, the festival's only performance of its kind. Highlights include Morikicho's own dashi float featuring Sugawara no Michizane and its horo-jishi lion float decorated with the character "mo." Also on display will be Morikicho's Odori Yatai, a dance stage float that was recently designated a tangible folk cultural property.
