Hiyashi Chuka (Cold Ramen), a Refreshing Ramen for Summer

Hello, ramen fans! The weather is gradually heating up, which means many of you are planning your summer vacations. As we enter the sweltering midsummer months, eating ramen with hot soup may sound more unbearable than enjoyable, even for the hardcore ramen fans. We understand why you might be tempted to reach for something that will cool you down, but we have great news for those who miss the delicious taste of ramen when it is too hot to enjoy it.

Did you know that there is a type of ramen that can provide cool relief in the midst of summer? In this article, we want to introduce Hiyashi Chuka (Cold Ramen), a refreshing alternative to the more common hot ramen. Hiyashi chuka directly translates to “Chilled Chinese,” though it is not of Chinese origin. The name refers to the cold Chinese noodles that are used in the dish. A chilled noodle may come as a surprise to those unfamiliar with cold soup, and some of you may be wondering how it compares. In terms of popularity, chilled ramen in Japan is now a seasonal summer favorite. After the rainy season ends and summer begins, ramen shops and Chinese restaurants display their signs to inform locals and tourists that hiyashi chuka is available. For Japanese people, enjoying hiyashi chuka on a hot summer day is almost customary.

In this issue, we will provide you, the ramen lover, with information on hiyashi chuka, a dish that is perfectly delicious for summer. We will also introduce a recipe that can be easily prepared, so please try it at home.

■The Characteristics of Hiyashi Chuka

what is hiyashi chuka

First, for those unfamiliar with hiyashi chuka, here are some basic characteristics of the dish.

  • Noodles
    It is made with boiled Chinese noodles that are chilled in cold or ice water, drained, and then placed on a plate.
  • Sauce
    Two types of sauces are commonly used: one is a refreshing combination of soy sauce and vinegar, and the other is a rich sesame-based sauce.
  • Toppings
    There are many variations, but we will list the most common. Ham, kinshi tamago (shredded, thinly sliced eggs), steamed chicken, and crab cakes are popular protein items, served with seasonal summer vegetables such as cucumbers and tomatoes. All these toppings are julienned into small pieces and arranged in a colorful, radial pattern that is characteristic of the dish.In addition, red ginger is often added as a garnish, with Japanese mustard as a condiment.


■History of Hiyashi Chuka

We have already mentioned that hiyashi chuka is a Japanese dish, but when and where did it originate? There are many theories, but we will explain the two most popular ones.

Some believe that the dish was first served in 1937 at the Chinese restaurant Ryu-tei (龍亭), in Sendai City, Miyagi Prefecture. At the time, Chinese restaurants did not cater to those seeking relief from the hot summer months, and to combat this, the owner of Ryu-tei invented ryan ban men (涼拌麺), which was served with a refreshing sour soup based on soy sauce and vinegar. At the time, cabbage and carrots were used as toppings in addition to today’s standard cucumbers and tomatoes.

The second theory to the invention of hiyashi chuka begins at Yosuko Saikan (揚子江菜館), a restaurant in Jimbocho, Tokyo. It is said that the dish originated from go syoku ryan ban men (五色涼拌麺) around 1933 and was inspired by the Shanghai cuisine of ryan ban men (涼拌麺) and Japanese zaru soba (cold soba noodles). The characteristic feature of this style is the radial arrangement of shredded toppings, a style that continues today. Fun fact: this stylized arrangement of toppings was inspired by the snowcapped Mount Fuji.

Therefore, it can be said that the modern hiyashi chuka is a combination of the taste of Ryu-tei seasoning and the presentation of Yosuko Saikan.

So far, we have traced the roots of the soy sauce and vinegar-based hiyashi chuka. Now, let us explore the history of the sesame-based sauce, the second most popular flavor for this ramen. The most well-known theory is that it originated when Chuka No Sakai (中華のサカイ) in Kyoto started serving hiyashi chuka with sesame sauce in 1939. Incidentally, this hiyashi chuka served in Kyoto was called rei-men (冷麺, meaning “chilled noodles”), and even today, hiyashi chuka is commonly referred to as rei-men in the Kansai region of Japan.

Finally, I would like to offer some insight into why this unique cold ramen variation originated in Japan. One of the main reasons is due to the accessibility of clean water throughout the country. Dishes such as zaru soba and somen (素麺) utilize cold water to cool boiled noodles and were popular before the creation of hiyashi chuka. It was likely that these dishes inspired the owners of Ryu-tei and Yosuko Saikan to use fresh, cold water to chill Chinese noodles.

■Q&A about Hiyashi Chuka

We have shared some basic information about hiyashi chuka, but if you have never tried the dish, it may be difficult to imagine its taste. So, we compiled a list of frequently asked questions about hiyashi chuka in a Q&A format.

Q1. How do you eat hiyashi chuka?
A1. There is no wrong way to eat hiyashi chuka. Even in Japan, there are two types of people: those who enjoy mixing it with other ingredients, and those who opt out of mixing it. You can eat hiyashi chuka whichever way you prefer. Something worth noting here is that Japanese mustard is very spicy, so be careful not to dissolve it into the soup all at once.

Q2. Is hiyashi chuka healthy?
A2. The calorie count of hiyashi chuka is said to be about 470 kcal, which is lower than the standard 680~730 kcal in shoyu ramen. In addition, the various ingredients (Chinese noodles, ham, eggs, and vegetables) in the dish promote a good balance of carbohydrates, protein, vitamins, and minerals.

Q3. Is it different from ramen salad?
A3. Ramen salad is made with crushed, dried noodles that are mixed with coleslaw and other ingredients that gradually moisten them, whereas hiyashi chuka uses Chinese noodles that are boiled and then cooled with cold or ice water. Also, the ingredients and sauces used in both dishes are vastly different.

■What is the Origin of the Name Hiyashi Chuka

As mentioned in the previous chapter, the name Hiyashi Chuka is generally used, although there are variations of the name, such as rei men in the Kansai region and hiyashi ramen (冷やしラーメン, meaning “chilled ramen”) in Hokkaido. In fact, the name “Hiyashi Chuka” is a recent term for the dish that is said to have caught on in 1960. The noodle manufacturing company, Daikyu Seimen (だい久製麺) in Sendai, where the aforementioned Ryu-tei is located, began selling a hiyashi chuka to make at home called Ganso Daikyu Hiyashi Chuka (元祖だい久 冷やし中華, meaning “original daikyu hiyashi chuka”). This product became instantly popular, leading to the variant terms such as Hiyashi Soba (冷やしそば, meaning “chilled soba noodles”), and Hiyashi Chuka Soba (冷やし中華そば, meaning “chilled chuka soba”) with Hiyashi Chuka (冷やし中華).

■July 7th is Hiyashi Chuka Day

Did you know that July 7th is actually Hiyashi Chuka Day? This day was registered by the Japan Anniversary Association in 1995 on behalf of hiyashi chuka lovers. The reason July 7th was chosen is because this day marks the beginning of Xiaoshu (小暑, the 11th term of the 24 solar terms in the Chinese calendar), when the rainy season ends to make way for the hottest time of the year. As previously mentioned, this is the best time to enjoy hiyashi chuka.
