Who would have thought you could find such authentic 100% buckwheat soba in the Sukhumvit Thonglor area? Nojian's "Tokyo Tsukesoba" is a popular dish featuring cold 100% buckwheat soba topped generously with braised pork belly and long green onions, served with a piping hot dipping broth.
"When you enter a soba restaurant, start with mori soba" — many people may have this habit.
But please pause for a moment and think.
Nojian, which hangs its noren curtain along Sukhumvit in Bangkok's Thonglor, quietly yet powerfully poses the question: "What is truly authentic 100% buckwheat soba?" Japan's soba culture is, in fact, remarkably vast. In Yamagata, there exists a bold way of eating called "ita soba," and a unique style using broth from mature hens known as "niku soba" has taken root there. Then there is the "Tokyo Tsukesoba" born from the shitamachi culture of Edo — another truly one-of-a-kind bowl in which the rich flavor of pork belly and long green onions is woven into the soba.
Nojian has gathered all of that under a single noren. In Thonglor-Sukhumvit, one of Bangkok's premier gourmet areas, the restaurant offers not only the classic mori soba but also an authentic menu that lets you experience soba culture from across Japan. Behind each "quiet bowl" lies a deep regional story.
In this article, we put the spotlight on Nojian's distinctive 100% buckwheat soba menu items, carefully explaining the origin and appeal of each one. By the time you finish reading, you will surely find yourself looking forward to heading to Thonglor, thinking: "What should I order next?"
"Ita Soba" — A Bold Bowl Embodying Yamagata's Rich Food Culture
When you hear the name "ita soba," what image comes to mind?
Just as the name suggests, it is soba served on a wooden board. This style, said to have originated in Yamagata Prefecture, is rumored to have begun as a way to serve soba in large portions for groups eating during breaks from farm work. Unlike the urban-style soba served in a zaru (bamboo strainer) or tray, ita soba offers a sense of "satisfying heartiness" and "open generosity."
The ita soba served at Nojian, located in the Sukhumvit area of Bangkok's Thonglor, is designed to draw out the full flavor of authentic 100% buckwheat soba. Paired with a delicate broth that does not overwhelm the aroma of the soba itself, you can taste the sweetness and nuttiness of buckwheat flour straight.
For those who want to "purely enjoy the flavor of authentic soba," we recommend ita soba without hesitation. It is a bowl of 100% buckwheat soba that evokes the rice paddy landscapes of Yamagata — simple yet profound.
"Yamagata Niku Soba (Currently in Preparation)" — A Unique Depth Born from Mature Hen Broth
In Kahoku Town, Yamagata Prefecture, restaurants serving "niku soba" line the streets one after another. For the locals, it is an everyday bowl and continues to be loved as "Yamagata's soul food" — yet in truth, it is rarely available in other prefectures, let alone overseas.
Its defining feature lies in the broth made from "oyatori" (mature hens). Unlike broilers (young chickens), mature hens that have continued laying eggs are muscular and tough. However, when simmered for a long time, their umami and fat melt into the soup, creating a deep, rich flavor that cannot be reproduced anywhere else.
Furthermore, Yamagata's niku soba includes a style of eating it "cold." When hot meat and broth are poured over cold 100% buckwheat soba, an exquisite temperature contrast is created, and the firm chewiness of the soba and the savory richness of the meat bring out the best in each other. This sensation is a discovery that only those who have eaten it can understand.
For those seeking authentic Yamagata flavors in Thonglor, Nojian's Yamagata Niku Soba is truly the only choice. Take one sip of the broth and anyone will immediately notice the difference. It is clearly deeper than "ordinary soba broth."
"Tokyo Tsukesoba" — Pork Belly and Long Green Onions: The Elegance of Edo-mae Brought into the Modern Era
Looking at the photo, your eyes are first drawn to the commanding presence of the pork belly.
Atop cold authentic 100% buckwheat soba served in a black bowl, thinly sliced seasoned pork belly and white long green onions are piled generously, decorated with a mountain of julienned nori seaweed. It looks like a visual that truly embodies "all toppings loaded." But this is not merely about visual impact. This composition is a condensation of Edo-mae food culture.
Tokyo's soba culture is characterized by a refined style: "dip only a small amount into the broth" and "treasure the condiments." With Tokyo Tsukesoba, you eat by passing cold 100% buckwheat soba through the piping hot dipping broth. The dynamic eating experience created by the contrast in temperatures sets it clearly apart from simple mori soba.
The fat from the pork belly and the umami of the broth intertwine, with the sharpness of the long green onion serving as an accent. After finishing the soba, you can also enjoy "soba-yu wari" — diluting the remaining broth with soba cooking water and drinking it. This bowl is an experiential design calculated to the very last drop.
If you are looking for authentic Edo-mae style 100% buckwheat soba in Sukhumvit Thonglor, there is no way you can skip this "Tokyo Tsukesoba." * You can choose between a warm dipping broth or a cold dipping broth.
Why Does Thonglor's Nojian Offer Such a Diverse Range of Authentic Soba?
With such variety on offer, some may wonder: "Why?"
Soba restaurant menus are generally simple. Mori soba, zaru soba, kake soba — and if there are any variations, they tend to stop at tempura soba or kamo seiro (duck soba). That was the "common sense" of Japan's soba restaurants. Even simply serving authentic 100% buckwheat soba overseas — particularly in a city like Bangkok — is in itself something special.
Yet Nojian is not bound by that "common sense." In Thonglor-Sukhumvit, one of Bangkok's leading gourmet areas, it has added ita soba, niku soba, and Tokyo Tsukesoba to its authentic menu, each in its original form. Behind this lies what appears to be a commitment to "conveying the diversity of soba in one place."
In Japanese food culture, "soba" takes on a completely different character depending on the region. The experiential value of being able to "encounter all of it at Nojian" is something not easily reproduced not only in Bangkok, but also in most other restaurants in Japan itself.
Conclusion: When You Come to Thonglor, What Will You Choose?
Let us look back at the three authentic menu items introduced in this article.
"Ita Soba," nurtured by Yamagata's rich rural culture. "Yamagata Niku Soba," condensing the deep umami of mature hens. And "Tokyo Tsukesoba" in the Edo-mae style, where pork belly and long green onions dance together. Nowhere else in Bangkok's Sukhumvit Thonglor area will you find authentic 100% buckwheat soba assembled with such care.
With so many choices available, if you always order the same bowl every time, that is perhaps a little unfortunate. Nojian quietly teaches us that soba, as a food, actually has such a diverse range of faces.
The next time you pass through the noren curtain in Thonglor, please take a good look at the menu. Spread across it, like a map, is the landscape of Japan's soba culture.
