Highlights

Outstanding Fish Raised in Turbulent Currents The Akashi Strait between Awajishima Island and Honshu is one of Japan fastest tidal channels, known for its swift currents. Akashi sea bream raised in these turbulent waters is prized for its firm flesh and concentrated umami. In spring before spawning it is called sakura-dai and is considered especially rich and delicious.

Uontana Shopping Street Uontana Shopping Street in front of Akashi Station is a fresh fish market with a long history. Sea bream, octopus, conger eel and other fresh local seafood line the stalls, and it is famous for hiru-ami, fish landed that very morning or midday. More than a hundred shops crowd together, offering dried fish, fish cakes, and local delicacies. Even just walking through it, you feel the energy of the port town.

Akashiyaki (Tamagoyaki) Akashi signature akashiyaki, sometimes called the ancestor of takoyaki, is a local dish. Soft round dumplings of wheat flour, egg, and octopus are eaten by dipping them in a light dashi broth, the Akashi way. Different in style from Osaka takoyaki, its melt-in-the-mouth texture is the appeal.

Its majestic form can be seen up close from the Maiko side. In Akashi, where longitude 135 degrees east and the Japan standard meridian pass, the Akashi Municipal Planetarium offers shows and exhibits about time and the universe.

Seasonal Enjoyment
