Hamada City Guide: Sea of Japan Coast, Aquas Aquarium & Fresh Seafood

Why Visit Hamada

Most travelers exploring Shimane head straight to Matsue's castle and lake district or the ancient shrine at Izumo. Hamada (浜田市), two hours further west along the Sea of Japan coast, rarely makes the itinerary — which is exactly why it's worth considering.

This small coastal city offers a different side of Shimane. Instead of shrines and samurai heritage, Hamada delivers a working fishing port, some of the best swimming beaches on the San'in coast, a surprisingly large aquarium, and seafood that rivals anywhere in western Japan. It's also closer to Hiroshima than to Matsue, making it a natural add-on if you're traveling through the Chugoku region.

Shimane Aquas Aquarium

Shimane Aquas (アクアス) is the region's largest aquarium, set along the coast near Iwami Seaside Park. The facility is popular with families and draws visitors from across western Japan. Aquas Land, an adjacent outdoor play area, gives kids space to run between exhibits.

The aquarium's main draw is its marine life displays showcasing creatures from the Sea of Japan and beyond. Check the official Shimane Aquas website for current admission prices and opening hours before visiting, as this information was not available at the time of writing. Local buses connect Hamada Station to the aquarium.

Beaches and Coastline

Hamada sits on one of the most scenic stretches of the Sea of Japan coast. The beaches here feature fine white sand rather than the rocky shores found elsewhere along the San'in coastline.

Kokufu Beach

Kokufu Beach (国府海水浴場) is a smooth, white sandy beach stretching approximately 1 km along the coast. According to Navitime, the shallow waters make it particularly safe for families with children. It's also a popular sunset photography spot, with views toward Iwami Dajimigaura, a designated national natural treasure.

Swimming season runs from mid-July to mid-August. During this period, parking costs ¥1,000 (~$7) per vehicle. Outside summer, the beach is still open for walks — just don't expect lifeguards or facilities.

Iwami Seaside Park

Iwami Seaside Park (石見海浜公園) stretches for five kilometers along the coast near Aquas aquarium. According to Japan Travel, the park features white sandy beaches and is one of the longest continuous beach areas in the region. Camping is available during summer, making it a good option if you want to combine beach time with an aquarium visit.

Many visitors stick to the main beach areas, but exploring the quieter coves along the coastline is highly recommended — you'll often find secluded spots with clear water and few other people.

What to Eat: Sea of Japan Seafood

Hamada's fishing port is one of the most active on the San'in coast, and the seafood here is a genuine highlight.

Nodoguro and Local Catches

The star of Hamada's seafood scene is nodoguro (ノドグロ), or blackthroat seaperch — a deep-sea fish prized across Japan for its rich, fatty flesh. The name literally means "black throat," referring to the dark coloring inside the fish's mouth. Nodoguro is typically served grilled with salt, as sashimi, or over rice. The freshest catches arrive from autumn through winter, though it's available year-round.

Beyond nodoguro, look for seasonal catches including squid, flatfish, and various shellfish pulled from the Sea of Japan. Local squid fishing fleets head out at night, and their lights create a distinctive scene along the coast.

Where to Find Fresh Seafood

The area around Hamada port has restaurants serving the day's catch. For the freshest options, ask locally about the fish market near the port — availability and opening times can vary. Restaurants at the onsen resorts in the area also serve regional seafood dinners.

Iwami Kagura Performances

Iwami Kagura (石見神楽) is a traditional Shinto performance art unique to the Iwami region of western Shimane. Described as some of the most energetic traditional dance entertainment in Japan, these performances combine elaborate costumes, dramatic storytelling, and dynamic choreography rooted in Shinto mythology.

According to Japan Travel, Mimata Onsen and Asahi Onsen — two of Hamada's four hot spring resorts — regularly perform Iwami Kagura for visitors. This makes an evening at a local onsen (温泉) doubly rewarding: soak in a natural hot spring, then watch a live kagura performance without needing to track down a separate venue.

Hamada has four onsen resorts in total — Mimata, Asahi, Yuya, and Kowa — each offering a different atmosphere. The cooler months from autumn through spring are particularly comfortable for onsen visits.

Getting to Hamada

Hamada is in western Shimane, roughly equidistant from Hiroshima and Matsue.

From Hiroshima:

• By car: approximately 2.5 hours via the Hamada Expressway
• This is often the most practical route, especially if you're renting a car for the Chugoku region

From Matsue:

• By JR train: approximately 2 hours
• Trains run along the San'in Main Line through scenic coastal countryside

Within Hamada:

• Local buses connect Hamada Station to Aquas aquarium and Iwami Seaside Park
• A car is helpful for reaching the more spread-out beaches and onsen resorts
• Parking is available at major attractions including Kokufu Beach (¥1,000 / ~$7 during swimming season)

Hamada Station is served by JR lines connecting to both Matsue and points south toward Hiroshima. If you're combining Hamada with other Shimane destinations, plan for the distances — western Shimane is genuinely remote, and train frequency is limited.

Frequently Asked Questions

Is Hamada worth a day trip or should I stay overnight?

A focused day trip works if you want to visit Aquas aquarium and one beach. However, staying overnight lets you explore the coastline at a relaxed pace, catch an Iwami Kagura performance at one of the local onsen resorts, and enjoy a proper seafood dinner. The onsen resorts double as accommodation, making an overnight stay easy to arrange.

How do I get to Hamada from Hiroshima or Matsue?

From Hiroshima, driving takes approximately 2.5 hours via the Hamada Expressway. From Matsue, JR trains take approximately 2 hours along the San'in Main Line. Within Hamada, local buses connect the station to Aquas aquarium and the beaches, though a rental car gives more flexibility for reaching the spread-out attractions.

When is the best time to visit Hamada for the beach?

Swimming season at Kokufu Beach runs from mid-July to mid-August, with lifeguards and facilities available during this period. Outside summer, the coastline is still scenic for walks and photography. Spring and autumn offer comfortable temperatures for sightseeing, hiking the Chugoku Nature Trail (中国自然歩道), and onsen visits.

What is nodoguro and where can I try it in Hamada?
