Ibaraki Prefecture, being on the Pacific coast, is renowned for its fresh seafood. While you won't typically find formal "tours" of the inner workings of fish markets like you might a factory, you can absolutely visit and experience the bustling atmosphere, buy fresh seafood, and enjoy delicious meals at the local fish markets.

The two main and most popular fish markets for tourists in Ibaraki are:

Option 1:

Nakaminato Fish Market (那珂湊おさかな市場 - Nakaminato Osakana Ichiba)

Option 2:

Oarai Seafood Market (大洗海鮮市場 - Oarai Kaisen Ichiba)

Nakaminato Fish Market is arguably the most famous and largest tourist fish market in Ibaraki. It's a vibrant hub where local fishermen bring their fresh catches directly from the adjacent Nakaminato Port.

What to Experience:

Fresh Seafood Sales: Rows of vendors proudly display a dazzling array of fresh fish, shellfish, and other marine creatures. You'll see everything from glistening tuna and local white fish like flounder and sea bream, to seasonal delicacies.

"Hamayaki" (Seaside Grill): A highlight is the "hamayaki" stalls where you can choose fresh seafood (like squid, scallops, oysters, shrimp) and have it grilled on the spot. The aroma is incredible, and it's a fantastic way to enjoy super fresh seafood on the go.

Restaurants: The market complex is packed with restaurants serving unbelievably fresh seafood dishes.

Must-try: Kaisendon (seafood rice bowls) piled high with various sashimi, sushi made with the day's catch, and seasonal specialties like anglerfish (anko) in winter.

Some popular restaurants include "Nakaminato-Hamagoya" and "Kaisen-sushi Kaikatei."

Souvenir Shopping: Beyond fresh seafood, you'll find a variety of processed seafood products, dried fish, local delicacies, and other Ibaraki souvenirs.

Lively Atmosphere: The market is always bustling with activity, especially on weekends and holidays. It's a great place to observe local life and the energy of a working fishing port.

Located closer to Oarai Fishing Port, Oarai Seafood Market is another excellent option for fresh seafood. It's often frequented by locals and can be slightly less overwhelming than Nakaminato on peak days, though it still gets busy.

What to Experience:

Direct Port Access: Being right in front of Oarai Fishing Port, you're getting some of the freshest possible seafood.

"Kaisen Donburi-Tei": This popular restaurant is adjacent to the market and opens very early, serving fantastic seafood rice bowls (kaisendon) with generous portions of seasonal ingredients. Their special kaisendon with 7-8 different kinds of fresh seafood is a highlight.

Hamayaki & Fresh Sales: Similar to Nakaminato, you can buy fresh fish and dried seafood, and also enjoy hamayaki on the premises. They often clean purchased fish free of charge.

In summary, for a "fish market tour" in Ibaraki, you'll be doing a self-guided exploration of these lively markets. Immerse yourself in the sights and smells, interact with the vendors, and most importantly, feast on the incredible fresh seafood!
