I visited Yamasei, located near Matsumoto Castle. The interior, renovated from a traditional house, features a modern Japanese style, and through the glass, there’s a courtyard that looks like a painting. The atmosphere is relaxing and welcoming, and the dishes we enjoyed were truly exquisite.The eel was perfectly cooked, with a crispy exterior and a fluffy interior, showcasing the quality of the ingredients through its thickness and delicate fat. Even for those of us who prefer the Kansai style,... More

This is an eel restaurant located in Matsumoto, Nagano.The prices are incredible.Please let me think about giving it a rating of 5 after visiting the first and second places.However, I believe this was undoubtedly the most delicious eel I've ever had in my life, regardless of the season.The experience was truly moving.The greatness was evident from the skewers, with a crispy skin that had an incredibly thin outer crust, giving it a texture reminiscent of a crème brûlée. The liver was wonderfully... More

This is a high-end eel restaurant renovated from a traditional Japanese house. The course includes a variety of eel dishes such as moringa somen, grilled liver, okra with sesame, white grilled eel, uzaku, eel rice bowl, and more. The eel is grilled to a perfect crispiness, with just the right amount of fat, making the eel course not too heavy. Although it’s not grilled over charcoal, this might be a matter of personal preference. Without the smoky coating, the natural aroma of the eel shines through,... More

On my way to Kamikochi, I stopped by Matsumoto for a stroll the day before. While the national treasure Matsumoto Castle was magnificent, the castle town itself was equally charming! With the Northern Alps as a backdrop, the retro streets harmoniously blend with new cafes and craft shops, creating a cozy atmosphere that I absolutely loved.After a day of sightseeing, I was eager to enjoy some delicious food, so I visited Yamasei, a renowned eel restaurant that I had reserved in advance through Tabelog.The...

I visited without a reservation, but luckily they were able to accommodate me! I love eel and eat it often, but this was my first time experiencing such a refined unaju that truly highlights the flavor of the ingredients. The aroma of the charcoal and the deliciousness of the eel filled my mouth with happiness... it was simply the best. The atmosphere and service in the restaurant were wonderful, and I would love to come back with someone special.

I had visited for lunch before, but this was my first time coming in the evening. The moringa somen, grilled liver, okra ohitashi, white grilled eel, eel salad, and eel rice bowl were all delicious. Additionally, the wine selection was outstanding. I would love to visit again when I come to Matsumoto in the fall.

【Visit】 I visited on a Saturday at noon. I made a reservation about two months ago. There were a few walk-ins on the day, but it seemed like they were fully booked with reservations and had to turn people away. 【Food, Service, Atmosphere】 The restaurant has a charming old house vibe, with the dining area located at the end of a narrow hallway after you open the door. I was warmly welcomed with attentive service. The interior features a wooden decor, and there was no background music,... More

I gave the highest rating in the unagi category on Tabelog! Located near Matsumoto Castle, this restaurant has won the Tabelog Bronze Award twice in just three years since relocating, and it has also been recognized as one of Japan's top 100 restaurants. It proudly ranks 10th in the nationwide unagi rankings! The exterior has a traditional kominka (old house) style, but once you step inside, you’ll find a stylish, modern space that still retains a Japanese aesthetic, complete with a beautiful... More

I visited for lunch. This eel restaurant has the best reviews in Matsumoto.I arrived around 1 PM and was told I could get in after a short wait, so I passed the time before returning.The unaju (grilled eel over rice) is priced in the 6,000 JPY range, which is quite bold. Of course, it’s delicious, and the pickles are excellent.The interior features a warm wooden counter and a few table seats. The courtyard design reminds me of a shop in Kyoto, which is quite stylish.It’s a relaxing place. Since... More

I had been eagerly anticipating the eel here ever since I made the reservation, counting down the days until my visit. The exterior is easy to miss if you don't know about it, but the interior is beautifully stylish. Despite being grilled eel, it was fluffy and didn't have an overly strong Kansai or Kanto flavor. The texture was crispy, with a delightful aroma, and the meat was tender. It was a perfect combination, and I enjoyed it immensely. I was also impressed by the shira-yaki (grilled eel without...

I made a reservation and visited on the weekend.I ordered the Unaju (grilled eel over rice), Shirayaki (grilled eel without sauce), and Kimo-yaki (grilled eel liver).Since it was the season for new eels, I was curious if they were new, and they had a nice, firm texture that I really enjoyed.The Shirayaki lived up to its great reputation on Tabelog, with a delightful texture that had a nice contrast, making it quite impressive.The Kimo-yaki had a slight bitterness that added to its depth, giving it...

I had the opportunity to visit Matsumoto for work, so I made a reservation and came to this restaurant. The grilled liver was incredibly delicious, far exceeding my expectations. I was impressed by the texture, grilling level, and aroma. The eel was also perfectly grilled, not crispy on the outside, but rather tender with a slightly sweet sauce. I truly enjoyed my time in Matsumoto.

If you love eel, you must visit Matsumoto. Yamasei is a representative eel restaurant in Japan. Here, the eel is grilled without steaming, resulting in a tender texture that melts in your mouth, thanks to their precise grilling technique. Additionally, they have dug a well in the basement to draw Matsumoto's underground water, which helps eliminate any unpleasant odors. The focus on achieving the highest quality for each dish is evident. The cold moringa served at the beginning, combined with wasabi,... More

The main event of my visit to Nagano was coming to Yamasei. I made a reservation through Ikkyu about a week in advance and secured a spot for noon on the day of my visit.The restaurant opened right on time. Although you can't tell from the outside, the interior has a view of a courtyard, creating a sophisticated atmosphere. I was seated at a spacious counter with ample distance between seats.I ordered the Unaju (grilled eel over rice) and grilled liver. The liver arrived first, about 20 minutes later.... More

During lunch,I made a reservation for a la carte.I ordered:Unaju (grilled eel over rice)Shirayaki (grilled eel without sauce)Kimo-yaki (grilled eel liver)Unfortunately, the soft-shelled turtle soup was sold out.Every dish was absolutely amazing!Truly delicious!You should definitely try both the kabayaki (grilled eel with sauce) and shirayaki!If they have kimo-yaki, it’s a must-try! I heard it might not always be available.

It seemed fully booked for reservations, but when I mentioned I was alone, they kindly accepted me. The exterior of the restaurant is easy to miss if you're not paying attention. Upon entering, you walk down a narrow corridor that leads to a spacious area filled with natural light from the courtyard, creating a truly lovely atmosphere. The garden is beautiful. It was just the right time as the lunch crowd was leaving, and a seat was prepared for me at the counter. The wooden counter feels great.... More

I visited Yamasei to celebrate my brother's return to Japan. The eel and soft-shelled turtle here are truly the best in the world! It seems that there are very few places in Japan where you can enjoy grilled soft-shelled turtle, so I believe it's worth traveling from afar just to dine at Yamasei. I had such a delicious and joyful experience!

Two years ago, I couldn't visit here and went to Unagi no Matsu Ka instead, so this time I made a reservation in advance at Yamasei, which is ranked 10th in the country.I was excited to discuss lunch with my friends since morning, debating between the Shirayaki Gozen and Unaju.We were seated five minutes before opening, and after looking at the menu, I ordered a beer, the recommended Japanese sake Daishinshu, Shirayaki (to share), and Unaju.I quenched my thirst with the beer. Then, Daishinshu—delicious!... More

I made an on-the-day phone reservation for a weekday visit in May. From the moment I called, the chef's polite response left a great impression. Upon arriving at the restaurant, the hostess was equally courteous, exuding the charm of a renowned establishment. I learned that they moved to this location three years ago, and the interior is stylish and clean. The garden visible in the back is also quite lovely. Now, onto the food: the shirayaki (grilled eel) was absolutely delicious! The skin was crispy,... More

I finally visited the renowned eel restaurant "Yamasei," which I had wanted to go to for a long time in Matsumoto City. It was a bit concerning to see only one group in line when I arrived at 11 AM, but as soon as I entered, the place was fully packed! The interior had a calm lighting that created a perfect atmosphere for enjoying the meal. After waiting for about 20 minutes, I ordered the Unaju (grilled eel over rice) and the Shira-yaki Gozen (grilled eel set meal). The moment I took a bite, the... More

Located in Matsumoto City, Nagano Prefecture, near Matsumoto Castle, this is an eel restaurant that I had been wanting to visit for a long time. I was very curious about how they prepare their eel so deliciously.Reservations are required, but it doesn’t seem too difficult to book. However, since there are only a few seats, it’s best to make a reservation early.I visited for lunch with a companion. We ordered a la carte:- "Shirayaki" (JPY 6,500) to share- "Unaju" (JPY 6,800) for myself- "Kabayaki"... More

Revisit: First visit after relocationI made a web reservation two months ago. The previous location was close to the station, but now it’s in a charming area with old houses, about a 15-16 minute walk from the station, past Matsumoto Castle. It seems they found a great property and decided to move.I entered the restaurant at 12:00. At the same time, there were two groups of four people. Five minutes later, the restaurant was fully booked. Inside, there’s a straight counter with 5 seats and two... More

I was able to make a reservation during Golden Week!First, I had the grilled eel served plain, paired with my usual hot sake.This sake, called "Misuzu," is a dry local brew that pairs perfectly with the eel's rich fat.The grilled eel had a unique texture I had never experienced before; the more I chewed, the more delicious it became.I wanted to pair my eel rice bowl with red wine, so I asked the owner for the wine list. Although I initially intended to go with a Pinot, I was informed they had a Grenache... More

I visited in early May. The course was beautifully structured to reflect the season, showcasing the best qualities of both eel and soft-shelled turtle, leaving no room for criticism from start to finish.The first dish, fiddlehead ferns with sesame dressing, immediately brought a spring-like atmosphere. It had the fragrance typical of wild vegetables, but the bitterness was not overwhelming, perfectly complementing the gentle sesame flavor. Next, the grilled eel liver was exquisite, with a delightful... More
