Vegetarian's Japan Guide

Tamaruya and Other Vegan-Friendly Mizusawa Udon Restaurant

If you plan to visit Ikaho Onsen in Gunma Prefecture, venture out to the Mizusawa region for the infamous Mizusawa Udon (水沢うどん) because it is one of Japan’s three most famous udons (the other two are Inaniwa Udon (稲庭うどん) from Akita Prefecture and Sanuki Udon (讃岐うどん) from Kagawa Prefecture)! The chewy and slightly thick noodles are made with only flour, salt, and Mizusawa’s fine water. The udon was first made for worshippers of the Mizusawa-dera Temple, which was why the udon was named Mizusawa.


Although you might think the noodles with a smooth texture originated from the locals selling the udon to Mizusawa Temple‘s worshippers, that wasn’t the case.

In the Sengoku period (1467 to 1567), the temple’s monks made udon noodles for the pilgrims at the temple so they wouldn’t starve while praying. By the end of the Sengoku period, a couple of udon makers already had a shop at the temple’s approach.

Apparently, only the 13 udon makers around Mizusawa Temple’s front gate were allowed to use the trade mark, Mizusawa Udon. Fortunately, 2 of the 13 udon specialists survived the test of time, so we can still taste the udon that the Japanese have loved for centuries, and Tamuraya is one of them.

A List of Restaurants Selling Mizusawa Udon

Tamaruya (田丸屋)

Tamaruya was established in 1582 and is one of the oldest udon makers in Mizusawa. While it looks like a typical traditional private house from the outside, it has a classy, traditional dining setting. The restaurant is so popular that a queue may have already formed by around 12 pm on weekends and public holidays. After all, the restaurant is huge. The chewy noodles are absolutely exquisite, and a short wait is worthwhile.

But don’t worry, the turnover is usually fast.

If there is a queue, get a number plate from the machine after inputting the number of people in your group and the preferred type of seat (the traditional Japanese seating on the tatami mats vs. Western-style dining tables). Private rooms are available too if you pay the extra charges. If you need assistance, the friendly staff will be more than happy to help you out.

Like a traditional ryokan, shoes need to be taken off at the entrance. While waiting, you can observe the elegant interior design. The high ceiling is like one of those in the luxurious ryokans.

Tamaruya’s Vegan Dishes

Among the meat and seafood-based udon menu, there is a vegan set menu, Shōjin Gozen (精進御膳). It was designed based on the menu from when the restaurant first opened in the 16th century. The sauce and broth used for the dishes included in the set menu are made from Konbu seaweed, mushrooms, and vegetables.

Note the photo is just an example of the set dish. Apart from the noodles and broth, what is served on the day can differ. But the taste is guaranteed!

Based on the day’s temperature and weather, the amount of each ingredient used to make the broth and noodles differs. This is how much effort Tamaruya puts into cooking to ensure the customers are happy with what they get on the tray. As you bite into the noodles, the nice aroma of wheat will spread in your mouth. The udon is so smooth you can easily swallow them without the dipping sauce!

Besides the typical Mizusawa Udon, Tamaruya also offers a special type of udon called Kirimugi (喜利麦), made from homemade whole wheat flour. The flat noodles are served in hot vegan broth and are consumed by dipping the noodles in olive oil and natural salt. Although Kirimugi was made using whole wheat flour, the noodles are smooth!

After finishing the meal, remember to check out the small garden beyond the corridor.

As soon as you are seated, tea and Ikaho Onsen‘s famous Yunohana Manjū (湯の花まんじゅう) are served. If you aren’t too hungry, leave the sweet buns at the end of the meal as dessert. If you like the manjū, purchase some from the souvenir shop next to the restaurant!
