I had a delicious carp sashimi and carp hot pot.

My wife had never eaten carp before, so I bought it as a souvenir. Unfortunately, there were no water shield leaves, so I bought the carp bones. My late father liked it, so I started to like it too. I have been buying it on my way back from Hakodate trips for over 30 years. After returning home, my wife and I had it while drinking in the evening. The vinegar miso was delicious, and this time there were fewer bones. It was delicious to eat carp bones after a long time. My wife also ate it for the first time and said it was delicious. I was worried about the smell, but it seems that there was no smell when eating it. Please enjoy it, everyone!

In mid-June, on the return trip from the third overnight stay in Hakodate, I decided to stop by "Koiya" at Junna-numa, which I had been curious about for a while, to try their famous carp dishes. The restaurant is located along Route 5, about 0.5 km on the left side after passing the intersection of Route 43 from Onuma Park towards Sapporo. We parked in the spacious parking lot, entered the restaurant, and ordered "Koi no arai (carp sashimi) for two." The staff asked if we wanted the carp scales, and of course we said yes! We also purchased two other smelt products and packed them in a foam box with ice. After enjoying a delicious "hamachanpon" in Naga-wanbe, I arrived home a bit later than my wife who had taken a different route. While my wife took a bath, I prepared the carp scales, and we had a satisfying dinner. The carp sashimi was served with a delicious mustard vinegar miso sauce, which enhanced the sweetness of the carp without any fishy smell. My wife, who is not a fan of raw fish, happily finished her portion. As for the carp scales, I followed the recipe and cooked them with carp, water, and miso, resulting in a rich and tasty dish. We froze half of the scales and enjoyed them a week later, finding them equally delicious. Although I have only tried carp dishes a few times, I have also enjoyed other fish from the carp family, such as Honmoroko, Ugui, and Sogyo, which all have a unique sweetness to their meat. Next time I pass by Junna-numa, I might buy some carp scales to try frying them. I just love carp! It was a delicious meal. Bon appétit!

Located along the Junnai swamp in Onuma, between the Onuma Tunnel and Onuma IC, is a historic restaurant that has been in business for nearly 30 years. You may not have heard of "koiai" before. It has a unique smell (which some may not enjoy), a crunchy texture, and a mild flavor, best enjoyed with vinegar miso. The preparation of "koiai" requires special skills, which is why it is not widely available. This restaurant offers "koiai" for free, making it a great deal. You can also purchase Wakasagi tsukudani and bracken fern unique to Onuma here. I often use this as a souvenir for my father, who always appreciates it. Some may feel uncomfortable eating carp, but there are edible varieties. If you have the chance, give it a try. Thank you for the delicious meal!

"MiyaKi Koiya" is a rare shop in Hokkaido that specializes in take-out carp dishes. Located along Route 5 in Nanai Town, this shop has a long history of serving carp dishes, which are known for their high protein, vitamin, and collagen content. Carp has been valued as a medicinal fish due to its nutritional benefits. The carp dishes are prepared using a method that involves briefly blanching the carp in hot water at around 65 degrees Celsius. In this shop, the carp sashimi is served with a mustard miso sauce, which complements the unique texture and flavor of the carp. Additionally, customers can also enjoy other traditional preserved fish dishes like sweetfish and shrimp. These dishes are made with minimal additives, using ingredients like water candy, brown sugar, and soy sauce, resulting in a sweet and rich flavor. The preserved fish dishes can be stored in the refrigerator for up to 3 months. Don't forget to try the complimentary carp bone dish, which can be used to make a delicious miso soup with extra sake for added flavor."

The shop is located on the left side a little past Junenuma, after coming out of the Onuma Tunnel and heading towards Sapporo from Hakodate on Route 5. I have stopped by a few times on my way back from Hakodate to buy carp sashimi. I think Miyazaki Koiya is the only place where you can easily buy carp sashimi. The carp meat is thinly sliced and already washed, so it is firm and has no fishy smell. It is very delicious when eaten with the special vinegar miso sauce. When you buy carp sashimi, you can also get carp scraps for free if you wish. The shop's brochure also introduces how to make carp broth, and I made it at home and enjoyed it. The shop also sells specialty products from Onuma, such as simmered wakasagi fish and river shrimp, as well as fresh water shield fern (junsai).

The carp here is really delicious! I'm not a big fan of freshwater fish, but I think the carp sashimi here is amazing. It has a nice crunchy texture with a good bite, and it goes perfectly with the mustard miso sauce! The large size is 1,200 yen, and the small size is 700 yen. I bought the small size this time, but it was enough for 2-3 people. It's not easy to find in Hokkaido, so if you have the chance, definitely try it out!

I received this as a souvenir. It's my first time seeing such small size sweetfish. It's not too sweet and has a lingering delicious taste. It shines beautifully and sparkles. It seems like it would take patience to cook something this small. My family said it was a bit fishy, but I enjoyed it bit by bit... It was delicious.

Whenever I go to Hakodate, I always make sure to stop by and purchase this. (*´∀｀*) This time, I heard that I was going to Hakodate, so I asked them to get it for me at this store. I saw for the first time that it was packed in styrofoam. They will pack it for an additional 200 yen. I appreciate that. I will enjoy it with mustard miso. It's super delicious! There are bones, but I don't mind at all. Soy sauce goes well with it, of course. It has a beautiful color. It's light, so it's practically zero calories, which is great, but I think it's low-calorie. (*^▽^*) I was curious, but once I tried it, it was really delicious, so I want everyone who hasn't tried it to try it. Fall in love with the carp! (*⁰▿⁰*) Thank you for the meal!

Whenever I go to the Ohnuma area, I always stop by Miyazaki Koiya to buy their "koi no arai" (carp sashimi). They also provide it as a complimentary service.

I received some pickled wakasagi from Ohnuma. I have a memory of delicious pickled wakasagi made by an old lady from Lake Notoro, which was quite large, so I am impressed by how well they cook such small ones. It was a delicious pickled dish made only from sugar, soy sauce, and malt syrup. You can slightly taste the bitterness of the fish's innards. It is recommended to store it in a cool, dark place (below 18°C), as putting it in the refrigerator will make it hard. Following this advice, I stored it in a slightly cold place and enjoyed it.
