Recommended sightseeing spots on the Oga Peninsula | Kanpuzan Mountain, Godzilla Rock, Nyudozaki Cape, and a scenic drive to enjoy the Sea of Japan [Oga Peninsula, Akita Prefecture]
There are two routes from Akita City to Nyudozaki, the tip of the Oga Peninsula: the "Namahage Line" and the "Oga Shiokaze Kaido" (Oga Coastal Road)
This article introduces viewpoints along the "Oga Shiokaze Kaido," a road that runs along the Sea of Japan coast of the Oga Peninsula
Kanpuzan Mountain, with its breathtaking 360-degree panoramic view, leaves you speechless

At the summit of Mt. Kanpu, located at the entrance to the Oga Peninsula, there are no trees or other obstructions to the view. There is an observation deck where you can see Mt. Nyudozaki, Lake Hachirogata (Ogata Village), and Mt. Chokai in the far south, allowing you to enjoy a 360-degree panoramic view
The fourth floor of the observation deck is a revolving observation deck (for a fee) that completes one rotation in 13 minutes, allowing visitors to relax on benches and enjoy the panoramic view

The observation deck features an information corner about the Oga Peninsula and Ogata Geopark, as well as a souvenir plaza. The restaurant serves local cuisine such as shottsuru yakisoba

Swallowed by a Namahage, we head to the "Oga Shiokaze Kaido"

This is a nickname for the combined route of Prefectural Road 59 and Prefectural Road 121, which runs from Wakimoto in Oga City along the west coast of the peninsula to Nyudozaki

At the entrances to the Oibanasaki Tunnel on National Route 101, which connects to this road, there are paintings of "Namahage" (a Japanese demon-like figure) that appear to swallow cars whole

The red "Hamahage" on the northbound lane seems to be the entrance to the Oga Peninsula, while the blue "Namahage" on the southbound lane seems to be the exit. I feel like this is the starting and ending point of the "Oga Shiokaze Kaido" (Oga Coastal Road)

For souvenir shopping and dining, we recommend "Michi-no-Eki Oga Namahage no Sato Ogare"!

Located near JR Oga Station, just after exiting the Ikebanazaki Tunnel, this roadside station offers fresh seafood directly from Oga's fishermen

Local seafood is a recommended souvenir, but sometimes there are no fish catches and the supply is limited, so it's a good idea to check the "Today's Availability" on the roadside station's official website before shopping

At "Oga's restaurant located on the best coastline in East Asia," you can enjoy local cuisine such as seaweed (gibasa/akamoku), sandfish dishes, and Oga's famous stone-grilled hot pot

Additionally, the rest area features a frozen food vending machine called "Kitchen Umainu," which sells dishes made with ingredients from Oga

The 24-hour rest area is equipped with a microwave, allowing you to enjoy local cuisine even when the restaurant is closed

Unosaki Coast (Unosaki Coast Geosite)

After leaving the roadside station and driving along the coast for a while, you'll see Unosaki Beach, one of "Japan's Top 100 Beaches."
This area is shallow for a long distance, and at low tide, the rocky seabed is exposed up to 200 meters offshore, making it famous for its unusual rock formations such as "Oni no Sentakuita" (Devil's Washboard) and "Azukiiwa" (Red Bean Rock)

When the weather is calm, the water's surface becomes like a mirror, and recently it has become a popular photo spot, often referred to as "Akita's Uyuni Salt Flats."

Godzilla Rock Roaring in the Sea of Japan

The entrance to Godzilla Rock is located at Shiosezaki, a short distance from Unosaki Beach, with the Sea of Japan on your left


Godzilla Rock is located at the tip of a cape, away from the road. You get out of your car in the parking lot and walk a short distance along the rocks on the coast towards Shiosezaki Lighthouse


There are signs indicating the direction of the rock, but there are no markers on Godzilla Rock itself, so it took some time to find it

When viewed in the bright daylight, Godzilla Rock looks like a natural rock formation, but when silhouetted against the setting sun, it has the awe-inspiring presence of a roaring Godzilla

Osanbashi Observation Deck

The name Daisankyo (大波橋) comes from the fact that the sea caves formed by wave erosion resemble a stone bridge spanning the sea

When I visited two years ago, it was just around sunset, and I was able to watch the sun sinking into the Sea of Japan

Since Osanbashi Pier is far from the observation deck of the "Oga Shiokaze Kaido" (Oga Sea Breeze Road), we recommend taking a sightseeing boat, which operates from late April to late October, to see it up close

Oga Aquarium GAO, an aquarium located near the sea

Since the birth of Momota, a polar bear cub, last year, and the opportunity to see his adorable appearance, many visitors have been coming to the zoo even on weekdays

For more details about Oga Aquarium GAO, please refer to our other article

There is a statue of the Virgin Mary on the way from the parking lot to the aquarium
This statue of the Virgin Mary was erected to commemorate a Swiss female tourist who died in the tsunami caused by the "Japan Sea Earthquake" that occurred on May 26, 1983
Even now, more than 40 years after the earthquake, many people still visit to pay their respects, and on the day I visited, beautiful flowers had been laid out

I took a little detour to Hachibodai

After passing Oga Aquarium GAO, the "Oga Shiokaze Kaido" road merges with Prefectural Road 121. Here, we recommend taking a slight detour to Hachibodai, one of the most scenic spots on the Oga Peninsula
From Hachibodai, you can see the maar formations of Ichinomegata and Ninomegata, as well as a panoramic view of Toga Bay, also known as Yonomegata, which is home to the Oga Aquarium and is also a maar formation
A maar is a circular crater-like landform created by a phreatomagmatic explosion that occurs when magma and groundwater come into contact underground
Because there is little ejected material, high mountains do not form, resulting in a landscape that looks like a gaping hole, and when water accumulates in it, these kinds of "lagoons" are formed

Nyudozaki, the tip of the Oga Peninsula

From Hachibodai, we return to Prefectural Road 121 and head towards Nyudozaki, the northernmost point of the Oga Peninsula, along the "Oga Shiokaze Kaido" road
If you were to compare the Oga Peninsula to a "thumbs up" hand sign, Nyudozaki would be the tip of the thumb

As the black and white striped "Nyudozaki Lighthouse" comes into view, you arrive at a large parking lot lined with restaurants

The area around the lighthouse is a plaza where you'll find the "Nyudozaki Bell of Hope" and one of the eight "40 Degrees North Latitude Monuments" installed from Iwate Prefecture to Akita Prefecture
