Sansai: The Sacred Spring Ritual of Wild Mountain Vegetables at a Hidden Tokyo Kaiseki Restaurant
Ancient Mountain Wisdom
The mountains of Japan have long provided people with bountiful gifts. Sansai, or wild mountain vegetables, embody the deep-rooted wisdom of Japan’s rural traditions and serve as a symbol of spring’s arrival. In kaiseki cuisine, these seasonal ingredients play a crucial role in expressing the changing seasons, offering diners a taste of nature’s rhythm. For centuries, the Japanese have cherished these seasonal blessings, embracing them as a means of absorbing nature’s energy through food.
Sansai are not merely natural produce; they represent the breath of life after enduring the harsh winter, a testament to Japan’s deep connection with nature. While they are now readily available in supermarkets, truly appreciating their essence requires an understanding of their harvesting methods and preparation techniques.
In this article, we explore the profound depth of sansai cuisine at Ise Sueyoshi, a hidden gem of a kaiseki restaurant in Tokyo’s Hiroo district, where tradition meets refined culinary artistry.
Spring Gifts Revealed
For centuries, sansai (wild mountain vegetables) have been deeply embedded in the culinary traditions of Japan’s mountainous regions. These resilient plants, which emerge with the arrival of spring after enduring the harsh winter, are celebrated for their vitality and nutritional richness. The techniques for harvesting and preparing sansai have been passed down through generations, embodying the wisdom and traditions of rural Japan.
Sansai foraging is not merely about gathering ingredients—it is a practice that reflects gratitude and respect for nature. This tradition aligns with Japan’s deep cultural values of sustainability, ensuring that the natural bounty of the mountains is preserved for future generations.
As the snow melts, delicate sansai sprouts appear, offering a tender texture and distinct aroma unique to spring. Some of the most well-known sansai include fukinoto (butterbur buds), tara no me (Japanese angelica tree shoots), koshiabura (a fragrant mountain vegetable), warabi (bracken), and zenmai (royal fern). Each of these ingredients brings a different texture and flavor profile, making them an essential part of Japan’s seasonal dining experience.
Beyond their preparation in tempura, ohitashi (blanched greens), and aemono (seasoned salads), sansai are an integral part of kaiseki cuisine, where their flavors, presentation, and seasonal significance are thoughtfully incorporated into each dish. At Ise Sueyoshi, a hidden kaiseki restaurant in Tokyo, sansai cuisine is elevated to an art form, with dishes that capture the fleeting beauty of spring through delicate plating, seasonal pairings, and time-honored techniques.
Autumn Harvest Feast
While sansai is often associated with spring, the mountains continue to provide an abundance of seasonal treasures throughout the year. Autumn, in particular, is a season of rich, earthy flavors, bringing forth an array of wild mushrooms, chestnuts, and natural yams (jinenjo). These ingredients, nurtured by the crisp autumn air, develop a deeper aroma and complexity, embodying the essence of the season.
At Ise Sueyoshi, kaiseki cuisine embraces the natural rhythm of the seasons, incorporating autumn’s finest mountain vegetables into exquisite dishes. Unlike the refreshing bitterness of spring sansai, autumn varieties offer a more profound, umami-rich experience, allowing guests to savor the tranquility and warmth of the season.
Each dish highlights the harmony between nature and tradition, offering a sensory journey through Japan’s autumn landscape. Whether it’s the delicate aroma of wild mushrooms, the nutty sweetness of chestnuts, or the smooth, earthy texture of natural yams, every bite reflects the changing seasons and the philosophy of mindful dining at Ise Sueyoshi.
Sansai and Vegan
Sansai (wild mountain vegetables) are an exceptional ingredient that can be fully enjoyed by vegetarians and vegans alike. Their rich, earthy flavors and seasonal vibrancy make them an ideal component of plant-based kaiseki cuisine, offering a deeply satisfying culinary experience without the use of animal-derived ingredients.
Spring sansai is known for its distinct aroma and refreshing bitterness, often surprising first-time diners with its unique character. Many international guests have described their first encounter with sansai as a completely new and unforgettable flavor experience. At Ise Sueyoshi, Chef Yuuki Tanaka’s mastery in traditional techniques and thoughtful preparation ensures that the natural taste of sansai is brought to life in every dish.

Traditional kaiseki typically relies on dashi (broth) made from bonito flakes, and the courses often feature seafood and other animal-based ingredients. However, this can pose challenges for vegan and vegetarian guests.
At Ise Sueyoshi, we believe that the beauty of kaiseki cuisine should be accessible to everyone, regardless of dietary restrictions. With this in mind, we began developing vegan kaiseki in 2016, striving to maintain the authenticity and depth of traditional Japanese flavors while ensuring that guests with plant-based diets can fully enjoy this exquisite culinary art.

Chef’s Mountain Memory
At the heart of Chef Yuuki Tanaka’s culinary philosophy lies a cherished childhood memory—foraging for wild mountain vegetables with his grandmother in the remote mountain regions of Mie Prefecture.
Each spring, he would search for bamboo shoots and warabi (bracken ferns), while in autumn, he would gather chestnuts. The joy of discovering these seasonal treasures firsthand left a deep impression on him. He fondly recalls the experience of bringing these ingredients home, where his father, Master Chef Sueyoshi Tanaka, would skillfully prepare them into delicious meals for the family.
Through these experiences, Chef Tanaka developed a profound respect for nature, an appreciation for seasonal ingredients, and a deep passion for food. These core values have become the foundation of his kaiseki cuisine.
The Philosophy of “Kokoro no Ryutsuu” (Circulation of the Heart)
One of Chef Tanaka’s guiding principles is “Kokoro no Ryutsuu,” or the circulation of the heart. This concept emphasizes sharing the stories, regional backgrounds, and dedication of producers through cuisine.
His childhood memories of foraging, selecting, and savoring the gifts of nature shape his approach to kaiseki. Each dish at Ise Sueyoshi is a tribute to the connection between the land, the ingredients, the producers, and the guests, ensuring that every meal is more than just food—it is a deeply meaningful experience.

My friend and I had been anticipating our return visit to Tokyo since March of this year. So it was wonderful for one of our first dinners to be at Ise Sueyoshi. Under the warm hospitality and refined palate of Yuuki-san, we were brought on a culinary journey through the myriad delicacies of Mie prefecture. Yuuki-san’s commitment and love for his hometown shone through his creative yet authentic renditions of the kappo style meal that was perfectly in tune with the autumnal produce paired with a bright Mie sake. The fact that we were the only 2 diners that sitting was a wonderfully extravagant privilege as we had the full attention of Yuuki-san but his exquisite cuisine and hospitality are too good to selfishly keep to ourselves- so we do hope that many more foodies will discover Ise Sueyoshi so that this gem of a restaurant can thrive as it so deserves. Domo arigato Yuuki-san. Ps: the restaurant is a bit hard to find with minimal signage so do allot more time to finding it- it’s in a small nondescript building and the signage indicating the restaurant is very tiny and only found once inside the lift on the button panel. So be brave and enter the lift despite the uncertainty!
