The Japanese prefectures of Ehime and Oita, situated on opposite sides of the Seto Inland Sea, offer a rich array of seasonal travel experiences centered on their renowned hot springs and cultural festivals. Both regions highlight traditional wellness attractions, including unique hot sand baths, as well as historic sites and scenic coastlines.
Visitors planning a trip in spring can witness cherry blossoms in full bloom, alongside vibrant festivals that celebrate local history and customs. Early April in Matsuyama, Ehime, features the Matsuyama Spring Festival parade, where participants of all ages dress as historical figures and march down Ropeway Shopping Street near Matsuyama Castle. Children don ninja costumes, while adults wear attire from various eras, including the Sengoku period (mid-15th century) and the Taishō period (early 20th century).
Concurrently, the Hatto Onsen Festival in Beppu, Oita, spans a week in appreciation of the onsen deity. A highlight of the festival is the Ogiyama fire event, during which locals ignite Mount Ohira (Ogiyama) by burning dried grass to encourage spring growth. The festivities culminate in the Yubukkake Matsuri water fight parade, where over 100 tonnes of hot spring water are splashed among participants.
In autumn, the landscape transforms dramatically, showcasing vivid foliage that enhances the region’s cultural landmarks. In Beppu’s Kannawa onsen area, hot spring steam mingles with crimson and gold autumn leaves, creating striking natural scenery often compared to cinematic visuals. The Beppu Ropeway offers panoramic views from up to 1,300 meters above sea level, and nearby Yujaku Park features around 500 maple trees (momiji and kaede) that light up in vibrant reds and golds. During the November Maple Festival, nighttime illuminations highlight the autumn colors, accompanied by seasonal treats like mugwort sweet dumplings.
Ehime hosts the Matsuyama Dogo Autumn Festival in October, centered on the Hachiawase ritual, which involves eight portable shrines (mikoshi) from different towns clashing in loud, spirited battles outside Dogo-Onsen station. Afterward, the mikoshi are carried up 135 steps to Isaniwa Shrine. Visitors can then continue to Matsuyama Castle to enjoy expansive views of autumn foliage and the surrounding city and sea.
Together, Ehime and Oita offer a blend of natural beauty, historic tradition, and culturally significant celebrations that provide travelers with an immersive experience of regional Japan through the changing seasons.
