Introduction to Shimanto Festivals in Shimanto City, Kochi Prefecture This introduces the local festivals that have been held in Shimanto City since long ago. 〇 Nakamura Region About 550 years ago, Norifusa Ichijo came down from Kyoto to the Nakamura Region, and many historic sites remain there, including streets and place names modeled after Kyoto. In the Nakamura Region, many festivals are held, including those associated with Tosa Ichijo. 1-1 Tosa Ichijo Kuge Gyoretsu (Fuji Matsuri) This event reenacts the arrival of Norifusa Ichijo, who left Kyoto in 1468 and took residence at Nakamura Gosho to restore the Hata manor, marking the foundations of Shimanto City. Modeled on Kyoto’s Aoi Matsuri court procession, the parade features a total of about 200 participants dressed in Muromachi Period costumes who march through the city. The colorful costumes, matching each role, unfold like a living historical picture. 1-2 Shimanto Citizen Festival The Shimanto Citizen Festival announces summer in Little Kyoto Nakamura. Organized mainly by the Shimanto Citizen Festival Executive Committee, a group of local volunteers, the festival includes citizen-participation events such as the Nakamura Dance parade and the lantern float parade. In particular, the powerful performance of the lantern floats, lit and paraded through the streets, offers inventive displays by each participating group and is well worth seeing. 1-3 All-Japan Jorogumo Sumo Tournament Long loved as a children’s summer pastime, this event is held on the first Saturday of August at Ichijo Shrine, located on a hill in the city center, as a summer memory for the children. Nationwide, this traditional event survives only in Shimanto City Nakamura and Kajiki Town in Kagoshima Prefecture. 1-4 Daimonji Bonfire The Daimonji Bonfire is an Obon custom in the Misaki district, Shimanto City, and a seasonal symbol that signals the end of summer in Little Kyoto Nakamura. On the 16th day of the seventh month of the lunar calendar, the slope of Todaijiyama (locally called Mt. Dainoji), where the mountain deity is worshipped, is carved into the shape of the character “大” and torches gathered from each household in the district are placed and burned. According to tradition, Fusaie, the son of Norifusa Ichijo, began this practice to console the spirits of Norifusa and his grandfather Kaneyoshi and to reminisce about Kyoto. Today, the event is run by local residents and delights many spectators as the "fire associated with Ichijo." 1-5 Shimanto Summer Fireworks Festival The Shimanto Citizen Festival, which heralds summer in Little Kyoto Nakamura, concludes with the Shimanto Summer Fireworks Festival, where music and fireworks perform together and a spectrum of colorful shells blaze into the sky. The fireworks reflected in the waters of the Shimanto River, called "Japan’s last clear stream," are simply exquisite. 1-6 Fuwa Hachimangu Grand Festival The Fuwa Hachimangu Grand Festival features the famous "marriage of the gods," with portable shrines of the male and female deities. After the male deity’s mikoshi, paraded through the town, awaits at Hachiman Shrine and the female deity’s mikoshi arrives, rituals such as the joining of the shrines are performed. This marriage ceremony of the deities is a rare ritual nationwide, said to have been started by Ichijo-ko, who enshrined the shrine, to discourage the then-common practice of abduction marriages. 1-7 Ichijo Grand Festival Since the establishment of Ichijo Shrine in the center of Shimanto City in 1862, this major festival has been held every year and represents Shimanto City. During the festival period, the sacred flame brought from Kyoto is displayed and many events, including a procession of children in historical costume, take place. 〇 Nishitosa Region The Nishitosa Region, located upstream in Shimanto City, features scattered riverside settlements and a peaceful landscape. In Nishitosa, traditional festivals passed down through generations are held in each district. 2-1 Iwama Boat Festival This ritual takes place at the summer festival of Iwama Tenmangu Shrine, when a mikoshi is placed on a boat and carried across the Shimanto River for a ceremony on the riverbank of the Kayou area. 2-2 Kondani Nembutsu Odori This Obon memorial ritual has been passed down in the Nishitosa Gonotani area of Shimanto City since around 1665. Bells and drums accompany the chanting of nembutsu, torches are lit on the riverbank for a water festival, and segaki memorial services and rites for newly deceased are performed. 2-3 Tachibana Mikoshi Boat Crossing In the Tachibana district, two shrines—Yasaka Shrine and Shiraiwa Shrine—face each other across the river, and on the eve of the autumn festival the sacred object is transported by boat from Shiraiwa Shrine to Yasaka Shrine. On the day of the autumn festival, after the rituals are held, the sacred object returns to Shiraiwa Shrine together with the mikoshi. 2-4 Hage Autumn Festival At the Hage Autumn Festival held at Hage Tenmangu Shrine, young people and children parade across the submersible bridge with the ox demon, mikoshi, and the flower-picking dance. The flower-picking dance is then performed on the shrine grounds. 2-5 Itsushika Odori Itsushika Odori is a traditional dance passed down through generations by local children and is dedicated at Kotohiragu Shrine during the Kotohira Festival in Nishitosanishikagata, Shimanto City.

[Kochi Prefecture Shimanto City] Flowers That Color the Shimanto River Basin 1. Climate of Shimanto City Shimanto City enjoys abundant forests, the clear Shimanto River, and the pacific ocean to its southeast, offering a rich natural environment. From 1991 through 2020, the average temperature was 16.5°C and the average annual precipitation was 2,877.9 mm, giving the area a warm, Pacific-type climate. 2. Flowers Nurtured by the Mild Climate [Spring] 〇 Around late February, when the spring sun begins to warm the days, the Iruta Yanagi Grove in the Shimanto River lower basin turns a tender yellow-green as new buds swell, and some 10 million rapeseed flowers bloom across the willow groves like a yellow carpet. This is an iconic scene that announces spring in the Shimanto River watershed. 〇 By late March, the cherry trees at the hilltop viewing spot Tamesho Park come into full bloom. Lanterns are lit during the cherry blossom season, letting visitors enjoy the night blossoms as well. The Shimanto City Local Museum sits nearby, so while learning about local history you can also take in the views from its observation floor. (Shimanto City Local Museum opening hours/9:00–17:00, closed/Wednesdays) At Shimanto River Sakura Zutsumi Park, neatly planted cherry trees and well-kept lawns invite visitors to sit and enjoy hanami while admiring the spring-bright Shimanto River. In the Shimanto River lower basin, plowing of rice fields begins around this time and the frogs start to call. 〇 When the cherry blossoms fall and the trees turn to leaf, look toward Kōzan-ji Temple to see the city flower, wisteria, paint the slopes purple. Kōzan-ji is also popular for hiking and birdwatching, and a park with play equipment makes it a favorite spot for families on holidays. 〇 In breezy May, roses and lilies cultivated by local residents brighten the pastoral inland landscapes in the Nishitosa area. Omiya Rose Garden welcomes visitors with about 500 rose bushes, while Nishitosa Yabukachi greets them with roughly 12,000 lilies. 〇 At this time of year, Shimanto Dragonfly Park shows dragonflies dancing above waters edged with water lilies and irises. Established in 1985 as the world’s first dragonfly reserve, the park has recorded 81 species of dragonfly. The Shimanto River Museum Akitsuio, attached to the park, exhibits insect specimens from around the world including dragonflies, alongside fish that inhabit the Shimanto River. (Shimanto River Museum Akitsuio opening hours/9:00–17:00, closed/Mondays) [Early summer] 〇 Under rainy, cloudy skies in June, Yasunami Waterwheel Village delights visitors with the rhythmic clack of turning waterwheels while hydrangeas along the waterways blaze with color. Sheltered pavilions near the channels make it pleasant to sit and watch the hydrangeas and the rural scenery. In the inland parts of Shimanto City, summer heat can be intense; when northwesterly winds blow, the foehn effect can raise temperatures and sea breezes from the pacific ocean have difficulty reaching inland, causing high heat. On August 12, 2013, Egawazaki recorded Japan’s highest temperature that year at 41.0°C. [Autumn] 〇 In late September, when the sky seems a little higher, the Iruta Yanagi Grove is enlivened by clusters of red spider lilies (manjushage) that dye the area bright red, and autumn insects begin to call from the grasses. Around this time the severe summer heat gradually eases. 〇 In early November, when autumn deepens, beautiful fall colors appear along the ravines of the Kurozon River, a tributary of the Shimanto River. [Winter] Although Shimanto City benefits from a mild climate, snow does fall some winters in the mountain valleys and on plains opening toward the Bungo Channel, and mornings and evenings often dip below freezing. Daytime, however, tends to be mild with many pleasant, sunny winter days. 3. Events to Celebrate the Arrival of Spring The Iruta Yanagi Grove, introduced above, hosts the Nanohana Festival. At the Nanohana Festival, the rapeseed flower groves spread like a yellow carpet and a variety of events are planned, including sales of local specialty products and wind band performances by junior and senior high school students. Please come and enjoy Shimanto River sightseeing when the rapeseed flowers are in bloom.
