X Kitchen Expands Ghost Restaurant Brand with Legendary Stamina Bowls

X Kitchen Teams Up with Legendary Stamina Bowl

In an exciting development in the ghost restaurant sector, X Kitchen, a franchise company based in Setagaya, Tokyo, has signed a licensing agreement with the iconic Stamina Bowl brand, "Legendary Stamina Bowl" (operated by Antworks Co., Ltd.). Starting June 24, 2026, this popular stamina bowl will be available exclusively through delivery channels, aiming to establish five new outlets by the end of the year.

Background of the Initiative

The dining landscape has significantly transformed in recent years, particularly after the pandemic, with delivery becoming an established norm for consumers. In this evolving market, delivery options have emerged as a novel revenue channel, separate from traditional dine-in services. However, many restaurants face ongoing challenges, such as labor shortages and rising costs of ingredients and utilities. Consequently, there's an increasing need for establishments to find viable ways to boost revenue without stretching their existing resources too thin.

To address these challenges, X Kitchen has developed a ghost restaurant franchise model that allows existing restaurants to leverage their current staff, equipment, and premises to enhance their delivery sales seamlessly. As of now, X Kitchen has approximately 1,100 franchise locations spread across the nation, reflecting the growing demand for its innovative business model.

Teaming up with a well-established brand like the Legendary Stamina Bowl provides franchisees with significant advantages. This brand comes with a longstanding reputation and a solid fan base, which means that locations can expect high customer traffic from day one.

What is the Legendary Stamina Bowl?

The Legendary Stamina Bowl brand was born in 1971 in Kunitachi, Tokyo, boasting a rich history of more than half a century. The origins of this brand can be traced back to hearty meals served in ramen shops. The passion for providing delicious and filling meals to energize customers has led to significant popularity over the years. Today, the brand has expanded to 193 locations nationwide as of June 2026 and is recognized as a highly reputable player in the food industry.

Their signature dish, the Stamina Bowl, features robust pork marinated in a secret garlic soy sauce, resulting in a rich and hearty flavor profile. Even the standard serving size is equivalent to about three bowls of rice, making it an irresistible choice for those looking to fuel up. This dish aligns perfectly with the growing demand for substantial meals through delivery services, making it a strong offering for X Kitchen's franchisees.

Future Expansion Plans

As X Kitchen embarks on this new venture with the Legendary Stamina Bowl, the company aims to open five new delivery outlets by the end of this year. The franchise model is designed so that partner locations can increase delivery sales without incurring additional fixed costs or hefty initial expenses. By continuously enhancing their offerings with high-profile licensing brands, X Kitchen intends to broaden revenue opportunities for its franchisees.

The company is committed to forging strong relationships with partners that have proven brand power, contributing to the growth of the delivery market as a reliable new revenue channel for restaurants.
