Yamagata Prefecture sits in the heart of Japan's Tohoku region, cradled by mountains on three sides and watered by the Mogami River that has shaped its culture for centuries. While winter transforms this area into a snow-covered wonderland, summer reveals a completely different character — one of exuberant dance festivals, misty mountain temples, and hidden onsen villages where time seems to slow to a gentle trickle.
August is arguably the finest month to visit Yamagata. The Hanagasa Festival fills the streets with color and rhythm, the ancient temple of Yamadera echoes with the chorus of cicadas that inspired one of Japan's most famous poems, and Ginzan Onsen's gas-lit wooden ryokan glow against the lush green gorge of summer — proving this fairytale town is far more than a winter destination.
The Hanagasa Festival (August 5-7)
Every August, Yamagata City erupts into three nights of joyful dancing as the Yamagata Hanagasa Festival takes over the main avenue. Considered one of the four great summer festivals of the Tohoku region, Hanagasa draws over a million spectators to watch roughly 10,000 dancers parade down a 1.2-kilometer stretch of the city center.
The festival's signature is the hanagasa itself — a straw hat decorated with brilliant crimson safflower (benibana), Yamagata's prefectural flower. Dancers hold these hats aloft, spinning, dipping, and flipping them in choreographed formations while singing the infectious "Yasshoo, Makashoo" chant that serves as the festival's heartbeat. The basic dance is simple enough for anyone to learn, and spectators are warmly invited to join a "free participation" section at the end of the parade.
Multiple dance styles coexist within the festival. The traditional "orthodox" style features graceful, flowing movements passed down through generations. The "creative hanagasa" style allows groups from companies, schools, and community organizations to develop their own choreography, producing everything from athletic acrobatics to comedic routines. Float trucks carrying taiko drummers and musicians weave between the dance groups, and the entire street throbs with energy from 6:00 PM until around 9:30 PM each night.
The best viewing spots are along Tokamachi-dori and the area near Yamagata Station. Arriving by 5:00 PM secures a good standing position; some spectators bring small folding chairs. The nearby Kajo Park, site of the former Yamagata Castle, hosts food stalls and entertainment during the festival period, making it a great spot to grab dinner before the dancing begins.
Yamadera: Where Silence Speaks
About 20 minutes by train from Yamagata Station, Risshakuji — universally known as Yamadera, or "Mountain Temple" — is one of Japan's most atmospheric sacred sites. Founded in 860 by the monk Ennin, the temple complex climbs up a steep, forested mountainside via a stone stairway of over 1,000 steps.
It was here, in the summer of 1689, that the haiku master Matsuo Basho composed his immortal verse: "Shizukasa ya / iwa ni shimiiru / semi no koe" — "Such stillness / the cry of cicadas / seeps into the rocks." Visit in August and you will hear exactly what Basho heard: the overwhelming, almost hallucinatory drone of cicadas that somehow deepens rather than breaks the mountain's tranquility.
The climb takes 30 to 45 minutes at a comfortable pace, passing moss-covered stone lanterns, ancient cedar trees, and small sub-temples tucked into rocky outcrops. The reward at the summit is the Godaido observation platform, which offers a sweeping panorama of the valley below — rice paddies, the Tachiya River, and the JR Senzan Line snaking through the gorge. In summer, the valley is a patchwork of vivid greens, and the cool mountain air provides welcome relief from the plains below.
Start early to avoid the midday heat. The temple grounds open at 8:00 AM, and morning light filtering through the cedar canopy creates an almost ethereal atmosphere. Bring water and wear sturdy shoes — the stone steps can be slippery. A small cluster of soba restaurants and souvenir shops at the base of the mountain makes for a pleasant lunch stop after the descent.
Ginzan Onsen: A Summer Secret
Most visitors associate Ginzan Onsen with winter — and understandably so, since photographs of its wooden ryokan draped in snow have made it one of the most Instagram-famous onsen towns in Japan. But locals will tell you that summer is Ginzan's best-kept secret.
Located in Obanazawa City, about 40 minutes by bus from Oishida Station, Ginzan Onsen occupies a narrow gorge along the Ginzan River. In summer, the steep hillsides burst with dense foliage that frames the three-story wooden ryokan buildings in a canopy of green. The river runs clear and lively, gas lamps flicker on at dusk, and the absence of winter's heavy tourist crowds means you can actually stroll the single main street at your own pace.
The town's name comes from the silver mine (ginzan) that once operated here during the Edo period. A short hiking trail leads to the old mine entrance and a small waterfall deeper in the gorge — a refreshing walk on a hot afternoon. The water temperature of the onsen baths ranges from 38 to 42 degrees Celsius, and several ryokan offer day-use bathing for visitors not staying overnight.
Summer evenings in Ginzan are magical. The gas lamps cast a warm amber glow on the wooden facades, fireflies occasionally appear along the riverbank in early August, and the only sounds are the rushing water and the gentle conversation of fellow bathers cooling off on the bridge. It feels like stepping into a Taisho-era postcard.
Beyond the Headlines: Yamagata's Summer Table
Yamagata's food culture alone justifies the trip. The prefecture produces over 70% of Japan's cherries (sakuranbo), and while the main harvest wraps up in July, late varieties linger into early August at local farm stands. The region is equally famous for its soba — particularly "ita soba," cold buckwheat noodles served on a large wooden board meant for sharing. The firm, nutty noodles pair perfectly with a dip of tsuyu and a side of tempura mountain vegetables.
As summer deepens, watch for "dashi" — a refreshing Yamagata specialty made from finely chopped cucumber, eggplant, myoga ginger, shiso leaves, and okra, seasoned with soy sauce and served cold over rice or tofu. It is the perfect antidote to August heat.
In September, Yamagata hosts the famous Imoni Festival along the Mamigasaki River, where a massive pot six meters in diameter cooks taro stew for 30,000 people — but the homestyle version appears on restaurant menus throughout late summer, a hearty preview of the harvest season ahead.
Getting There & Practical Tips
Yamagata City is roughly 2.5 hours from Tokyo via the Yamagata Shinkansen (Tsubasa), making it an easy weekend trip. The JR Senzan Line connects Yamagata Station to Yamadera Station in about 20 minutes. For Ginzan Onsen, take the Yamagata Shinkansen to Oishida Station and transfer to the Hanagasa Bus (about 40 minutes).
A rental car opens up more of the prefecture — the drive between Yamadera and Ginzan Onsen passes through rolling countryside and takes about 90 minutes. Summer temperatures in Yamagata City can be surprisingly hot (the city once held Japan's record high temperature at 40.8°C), so pack light clothing, sun protection, and plenty of water. The mountains and onsen towns are noticeably cooler.
For the Hanagasa Festival, book accommodation well in advance — Yamagata City's hotels fill up quickly during festival week. Alternatively, base yourself in nearby Tendo (famous for shogi chess pieces and its own onsen) and commute by train.
