First 10th Anniversary Campaign: New Spicy Broths 'Mala' and 'Green Chili & Organic Lemon' Launch in Selectable Two-Flavor Shabu

Official Website of 'Okaka'

'Okaka Dashi Shabu Obaanzai', operated by Brand Bank Company, Ltd. (Headquarters: Shinjuku-ku, Tokyo; President & CEO: Juichi Nemoto), celebrates its 10th anniversary in 2026.

To express gratitude to its loyal customers, Okaka will sequentially launch its 'Okaka 10th Anniversary Campaign'.

As the first initiative, starting July 7, 2026 (Tuesday), two new spicy broths—'Mala Broth' and 'Green Chili & Organic Lemon Broth'—will debut in the 'Selectable Two-Flavor Dashi Shabu', marking the first time Okaka offers a spicy broth enhanced with 'katsuo-bushi' (bonito flakes).

The 'Mala Broth' features a bold, complex flavor inspired by mala hot pot, combining the heat of chili peppers with the aromatic numbing sensation of Sichuan peppercorns. Built on Okaka’s signature dashi, it layers sharp spiciness and refreshing tingling notes that enhance the umami of Kagoshima black pork and the natural sweetness of vegetables. It pairs perfectly with slippery cellophane noodles.

The 'Green Chili & Organic Lemon Broth' blends the sharp heat of green chili paste with the bright, zesty aroma of pesticide-free lemons. The first sip delivers a burst of lemon freshness, followed by a kick of green chili spice—an invigorating flavor designed to stimulate appetite during hot summer months.

Additionally, at the Shinjuku location, the popular 'All-You-Can-Eat Seasonal Vegetables' promotion, which received high praise at the store’s opening, returns for a limited time. Guests can enjoy a colorful array of fresh seasonal vegetables—such as lettuce, leeks, mizuna, radish, and mushrooms—paired with Okaka’s aromatic dashi to their heart’s content.

Okaka continues to deliver its unique dining concept of 'eating dashi', now enhanced with bold new flavors of spice and freshness, honoring a decade of culinary dedication.

Perfect for hydration and electrolyte replenishment during summer, why not power through this season with Okaka’s revitalizing 'Dashi Shabu'?

About 'Dashi Shabu Obaanzai Okaka'

'Dashi Shabu Obaanzai Okaka' takes its name from 'katsuobushi' (bonito flakes), reflecting its pride in premium 'honkare' katsuobushi, shaved to 0.01mm thinness at the counter. The centerpiece is the additive-free, flavor-enhancer-free 'dashi shabu', generously topped with freshly shaved katsuobushi. The dashi, crafted from an original blend, is finished with 'oikatsuo' (additional katsuobushi) right before guests, releasing rich, layered aromas.

Thinly sliced meat and seasonal vegetables are briefly dipped into the dashi upon order, delivering the core concept of 'eating dashi'. This is a restaurant where you can enjoy comforting, body-friendly cuisine made possible only by the fresh, aromatic katsuobushi dashi.
