Discovering Iwaki: One of Tohoku's Most Diverse Cities
Iwaki City stretches across a vast area of southern Fukushima Prefecture, offering an unusually wide range of experiences for visitors — from dramatic Pacific coastline to forested mountains, and from cutting-edge aquariums to ancient shrines. Whether you're planning a day trip or a longer stay, Iwaki rewards exploration at every turn.
Aquamarine Fukushima
No visit to Iwaki is complete without spending time at Aquamarine Fukushima, one of Japan's most acclaimed aquariums. Opened in 2000, it focuses on the rich marine ecosystems where the warm Kuroshio Current meets the cold Oyashio Current — right off Iwaki's coast. The result is extraordinary biodiversity, and the aquarium showcases it beautifully.
- Over 450 species of marine life on display
- Stunning open-ocean tank with sunfish, sharks, and bluefin tuna
- Outdoor "Jomon no Mori" forest garden with traditional thatched structures
- Family-friendly with excellent accessibility
The aquarium sits right on the coast at Onahama, making it easy to combine with a seaside walk afterward.
Iwaki Marine Tower & Onahama Waterfront
Standing near the aquarium, the Iwaki Marine Tower offers panoramic views of the Pacific Ocean and the surrounding coastline. The Onahama waterfront area has a lively port atmosphere, with fresh seafood available at nearby restaurants and market stalls.
Shiramizu Amidado Temple
For history lovers, Shiramizu Amidado is an absolute must. This National Treasure-designated temple hall dates back to 1160, making it one of the oldest surviving wooden structures in the Tohoku region. The surrounding Jodoteien garden — a Heian-period paradise garden — is serene and photogenic, especially when the lotus flowers bloom in summer.
Iwaki Yumoto: Onsen Town
The Yumoto district in the western part of the city is Iwaki's traditional hot spring hub. The streets retain a nostalgic showa-era feel, with small ryokan inns, foot baths, and local sake shops. It's a great place to slow down and experience a different side of Iwaki from the coastal bustle.
Misato Stone Buddha (Misato Sekibutsu)
Hidden in the hills of Iwaki's interior, the Misato Stone Buddha cluster is a haunting and beautiful site. Dozens of rock-carved figures dating from the Heian period emerge from mossy cliffs in a forested valley. The atmosphere is deeply peaceful and unlike anything else in the region.
Coastal Scenery: Ena, Yotsukura & Hisanohama
Iwaki's coastline stretches for dozens of kilometers, offering several distinct scenic spots:
- Ena Lighthouse area — dramatic rocky cliffs and ocean views
- Yotsukura Coast — rugged natural rock formations and clear water
- Hisanohama Beach — a wide sandy beach popular in summer
Getting Around Iwaki
Iwaki is a large city and public transport is limited outside the main JR Joban Line corridor. Renting a car is strongly recommended for exploring attractions spread across the city. Major car rental agencies operate near Iwaki Station. Taxis and local buses cover some tourist routes, but schedules can be infrequent.
From Tokyo, Iwaki is accessible in about 90 minutes via the JR Joban Line Limited Express from Shinagawa or Ueno stations — a convenient and scenic journey through coastal Ibaraki.
