Two and a half hours south of Tokyo, the bullet-shaped Izu Peninsula dips into the Pacific like a toe testing the water. At its very tip sits Shimoda, a small port town that most international visitors have never heard of — and that's precisely what makes it so special. In June, while Kamakura and Hakone draw hydrangea crowds by the busload, Shimoda quietly stages one of Japan's largest ajisai displays with a fraction of the tourists. Add turquoise coves that rival Okinawa, a pivotal chapter of Japanese history, and some of the freshest seafood on the Pacific coast, and you have the makings of a perfect early-summer escape.
A Sea of 300,000 Hydrangeas
The Shimoda Hydrangea Festival (June 1–30) transforms Shimoda Park into a rolling carpet of blue, purple, pink, and white. The park sits on a hillside overlooking Shimoda Harbor, and its roughly 300,000 hydrangea bushes — one of the largest collections in Japan — cascade down slopes that once served as a castle lookout during the Sengoku period. Walking paths wind through tunnels of blossoms, opening up to panoramic views of the harbor and the open sea beyond. The peak bloom window usually falls in the second and third weeks of June, though the festival runs the entire month. Arrive early in the morning on a weekday if you can; even in this relatively under-the-radar spot, weekends during peak bloom attract domestic day-trippers from Shizuoka and the wider Kanto region.
Where the Black Ships Changed History
Shimoda's other claim to fame dates to 1854, when Commodore Matthew Perry's fleet of 'Black Ships' anchored in the harbor, effectively forcing Japan to end over two centuries of isolation. The town wears this history lightly and elegantly. Perry Road is a short, willow-lined canal path connecting the harbor to Ryosen-ji Temple, where the Treaty of Shimoda was negotiated. The stone-paved lane is flanked by converted Meiji-era warehouses that now house cafés, antique shops, and galleries — the kind of strollable quarter that begs you to linger. Inside Ryosen-ji's grounds, the Black Ship Museum offers a compact but fascinating collection of Perry-era artifacts, woodblock prints, and letters. It's one of the few places in Japan where you can literally stand in the room where the country's modern diplomatic history began.
Beaches Worth the Detour
Many first-time visitors do a double take at Shimoda's beaches. Shirahama Beach, just north of the town center, stretches 800 meters of white sand against remarkably clear, blue-green water. It is consistently ranked among the top beaches in mainland Honshu and feels a world away from the gray pebble shores that typify much of Japan's Pacific coast. While the official ocean swimming season opens in mid-July, June is ideal for walking the sand, surfing (Shirahama is a year-round surf spot), or simply spreading a towel and reading to the sound of waves. A handful of beachside cafés open for the summer season, serving shaved ice, acai bowls, and local craft beer. Further south, Tatado Beach and Kisami Ohama offer quieter coves for snorkeling and stand-up paddleboarding once the water warms up.
Seafood, Onsen, and Kinme-dai
No trip to Shimoda is complete without kinme-dai (golden-eye snapper), the town's signature fish. This deep-water species has rich, fatty flesh that locals prepare simmered in soy (nitsuke), as sashimi, or grilled with salt. Almost every restaurant near the harbor offers a kinme-dai set meal, and the quality here rivals what high-end Tokyo sushi bars charge three times more for. After eating, soak in one of the area's onsen. Shimoda sits on the southern Izu hot-spring belt, and several ryokan and public baths offer ocean-view soaking. Kanaya Ryokan, perched above the harbor, has a rotenburo (outdoor bath) with sunset views across the bay that alone justify the visit.
Getting There & Practical Tips
From Tokyo, the most scenic route is the JR limited express Saphir Odoriko, which runs from Tokyo or Shinjuku Station directly to Izukyu Shimoda Station in about 2 hours 40 minutes. The train hugs the coast of Sagami Bay for much of the journey — book a window seat on the left side for the views. A regular Odoriko express takes about 3 hours and costs less. By car, the drive from Tokyo via the Tomei Expressway and Izu Jukan Expressway takes roughly 3 hours, though traffic on summer weekends can add considerably to the journey.
Once in Shimoda, the town center is compact and walkable. Shimoda Park is a 20-minute walk from the station, or a quick ride on the local loop bus. Shirahama Beach is one stop north on the Izukyu Line or about 10 minutes by taxi. Bicycle rental shops near the station are another excellent option — the coastal roads are flat and scenic.
June is the start of tsuyu (rainy season) in Izu, but don't let that deter you. Hydrangeas look their best in the rain, and many visitors find the misty harbor views more atmospheric than a bluebird day. Pack a compact umbrella, wear shoes that can handle wet stone paths, and embrace the season.
