Seasonally Inspired Delights: On-Yasai's New Autumn Menu

As autumn approaches, the popular Shabu-Shabu On-Yasai, a brand of Reins International Co., Ltd., is set to unveil its latest seasonal offering. Starting September 16, 2026, diners can indulge in the limited-time “Soy Milk Porcini Shabu-Shabu” along with the beloved “Duck Shabu,” which has significantly evolved this year.

Introducing the New 'Autumn Shabu' Experience

Creamy and Aromatic Soy Milk Porcini Shabu-Shabu

This autumn, On-Yasai presents an exciting variation of its signature dishes with the introduction of the rich and creamy Soy Milk Porcini Shabu-Shabu. Known for its exquisite flavor, porcini mushrooms, recognized as one of the world’s top three mushrooms, offer an unforgettable fragrance to this seasonal delight.

The soy milk-based broth, infused with the deep flavor of porcini, envelops the ingredients in a cozy autumn atmosphere. With seasonal vegetables like the “Kabu Toro Nameko,” paired perfectly with mushrooms and various vegetables, each bite highlights the unique flavors of the ingredients used.

Unforgettable Pairings with Pork and Duck

In addition, the Shabu-Shabu's unlimited course offers the duck option, harmoniously blending the rich and sweet taste of pork with the umami of duck, ensuring that your dining experience is satisfying till the very last bite. Diners can now savor the luxurious combination of porcini's elegant aroma and the intense flavor of duck meat - a true indulgence for the fall and winter seasons.

The Classic Duck Shabu with an Innovative Twist

Available for over ten years, the classic “Kiwami Dashi Duck Shabu” will also make an appearance within the limited-time offerings. Each slice of the tender duck, when swirled in the fine “Kiwami Dashi,” enriches the soup with its deep flavors. Complementing this exquisitely is the limited seasonal offering of the “Shallot Mix.” When enjoyed together, the gentle sweetness of the shallots enhances the duck's umami, allowing you to relish in the deliciousness all the way to the final drop.

Experience the New 'Creamy Soy Milk Porcini Broth'

A Unique Broth Experience

The “Soy Milk Porcini Dashi” is a first for On-Yasai, bringing together the flavor of the porcini with chicken and aromatic vegetables, combined with a rich soy milk base. This exquisite broth offers a well-balanced taste experience, featuring a gentle richness that complements the luxurious moss of the porcini.

Ideal Meat Pairings

The robust “Soy Milk Porcini Dashi” is best complemented by soft pork known as “Sangen Pork Shabu.” The tender meat and the melt-in-your-mouth sweetness of the fat brings out the soothing flavor of the broth remarkably. During the unlimited course, guests can also sample duck meat, allowing for an unforgettable autumn and winter dish.

Seasonal Vegetables to Enhance the Experience

The special seasonal vegetable “Kabu Toro Nameko” pairs beautifully with the dish. This unique nameko mushroom has a larger size than usual, offering a crunch and a tender yet smooth mouthfeel. Additionally, On-Yasai supplies a diverse selection of mushrooms, including “Aji Enoki,” “Matured Maitake,” “Thick Shiitake,” “Supreme White Maitake,” and “Buna Shimeji,” all of which can be enjoyed in a flavor contrast within the dining experience.

A Touch of Spice

Adding black pepper introduces a unique zing to the smooth and calming taste of the “Soy Milk Porcini Dashi,” emphasizing the rich flavor of the porcini. This slight kick ensures that guests remain engaged with each bite.

The Ultimate Conclusion to the Meal

To fully savor the rich, blended essence of the broth, customers can indulge in the provided “Cheese Risotto Set”, where creamy cheese marries with porcini’s delightful aroma for an impactful culinary conclusion.

The Signature Duck Shabu with Zesty Dipping Sauce

Elevating the Experience with ‘Mikan Yuzu Pepper’

Continuing the innovation, the “Kiwami Dashi,” developed specifically for duck shabu, shines through. This broth, enhanced with “Handmade Katsuobushi” and a rich blend of seafood flavors, offers a delicate sweetness and nuanced aroma, deepening further with the richness of duck flavor.

Recommended Meat Pairing

Duck meat shines in this broth. When colliding with the heat of the dashi, it becomes tender and flavorful, leaving diners savoring the layered flavors on their palate.

Seasonal Vegetables Enhancing Flavor

The recent “Seasonal Shallot Mix” features a delightful combination of domestic Kujo shallots and herbal shallots, cut at an angle to fully mesh with the broth. This refined selection is designed to maximize broth absorption.

Unique and Flavorful Condiment

The unique “Mikan Yuzu Pepper” creates a soothingly fruity aroma, providing a spicy twist that lets the duck flavor shine brightly. Fully blended in-house, this dynamic flavor enhances the main dish experience.

The Cleaning Closure with Duck Soba

To fully appreciate the dashi infused with the essence of both duck and seasonal vegetables, guests are recommended to try the “Duck Soba.” With the robust texture of hand-cut soba noodles, the broth offers a taste masterpiece curated from the Shabu-Shabu experience.

Enjoy Unlimited Seasonal Domestic Vegetables!

At On-Yasai, a constant selection of fresh, seasonal domestic vegetables totaling up to 15 varieties is available, alongside a rotating lineup of seasonal produce. By dipping these in the special dashi, the natural sweetness and texture of the vegetables come to life.

Dessert Delight with Esteemed Chef Takahiro Komai

On-Yasai also introduces the exclusive “Chestnut Catalana” – a fall dessert crafted by world-renowned pastry chef Takahiro Komai. This rich dessert seamlessly merges chestnut paste and custard, garnished with caramelized chestnuts for a crunchy finish.

Easy-Going 'Gohan Sets' for One
