Overview (history, characteristics, attractions)

Asamushi Onsen is a seaside hot spring resort facing Mutsu Bay in the northeastern part of Aomori City. It has long been popular as a local hot springs resort, and has developed into a resort where you can enjoy both ocean views and hot springs. The hot springs are characterized by their soft texture, and can be enjoyed alongside the seasonal scenery, such as the snowy landscapes of winter, the sea breeze of spring, and the cool breezes of summer. There are many inns that serve dishes that make use of fresh seafood (especially shellfish and squid), and there are also a number of day-trip bathing and footbath spots scattered around, making it an ideal place for a casual stop.

Highlights

  • Hot spring town along the coast: Lined with accommodation facilities, public baths, and foot bath spots, you can enjoy the sea view while strolling.
  • Asamushi Aquarium (Aomori Prefectural Asamushi Aquarium): This aquarium mainly exhibits creatures from Mutsu Bay and is popular with families and tourists (occasionally holds events and dolphin shows).
  • View of Mutsu Bay: The scenery across the bay and the sunset are beautiful, making it a recommended photo spot.
  • Local seafood: Dinner is a major attraction, with many inns serving fresh sashimi, shellfish, scallops and squid dishes.
  • Walking trails and parks: Relax along the seaside walks and in nearby parks. Depending on the season, you can enjoy cherry blossoms and seaside flowers.

  • Crowds: Hotels and day-use facilities tend to be crowded on weekends, holidays (Golden Week, Obon, New Year's) and during peak tourist seasons, so we recommend making reservations in advance.
