【Japan's 'Least Photogenic but Most Delicious' Hot Pot Returns to Azabu-Juban!】 〜'Yamaimo no Ooi Ryōriten' is BACK!!〜

### 〜The Hot Pot,話題 for being 'too brown,' makes a comeback in the heart of Azabu-Juban shopping street〜
Eureka Kitchen & Lab Co., Ltd. (Headquarters: Kawasaki City, Kanagawa Prefecture; Representative Director: Naoya Hikane), which operates 'Yamaimo no Ooi Ryōriten,' will relocate and reopen 'Yamaimo no Ooi Ryōriten Azabu-Juban,' which had been closed for relocation, on April 7, 2026 (Tuesday), within the Azabu-Juban shopping street (next to McDonald's).

Prior to the opening, for two days from April 3 (Friday) to April 4 (Saturday), as a pre-opening period also serving as staff training, we will offer a 30% discount on the bill exclusively for reserved guests.

- The hot pot, said to be Japan's least photogenic, won the first Grand Prix at the 'National Hot Pot Election in Red Brick Warehouse.'

### ■What exactly is 'Yamaimo no Ooi Ryōriten'?：A unique sanctuary for yams
Our restaurant is a one-of-a-kind specialty restaurant that comprehensively handles yams, from familiar types such as Jinenjo (wild yam), Nagaimo (Chinese yam), and Yamatoimo (Japanese yam) to rare varieties.

We use yams directly sourced from farmers. With the concept of 'maximizing the potential of yams,' our menu boasts over 70 dishes. From sashimi, fried dishes, grilled dishes, and our famous hot pot, to desserts and even 'Jinenjo Beer that can only be drunk here in the world,' we constantly propose new ways to enjoy yams.

- Murata's Jinenjo, Nakazawa's Nagaimo, and Tako farmers' Yamatoimo
- Nagaimo Pork Roll Steak
- The appetizer is a tasting comparison of three types of grated yam.
- Only here in the world! Jinenjo Beer

Before its relocation, our restaurant was incredibly popular, recording over 3.5 on Tabelog and having all seats reserved daily. It also generated significant buzz on social media, with an Instagram Reel video surpassing 3 million views.

### ■The authentic taste proven precisely because it's 'Japan's least photogenic'
Our signature dish, 'Jinenjo Tororo Nabe' (wild yam grated hot pot), proudly won the 【First Grand Prix】 in the '1st National Hot Pot Election,' the main event within 'Sake Dokoro Nabe Goya' held at Yokohama Red Brick Warehouse in January of this year, based on votes from a total of 220,000 visitors.

Because it uses rare Jinenjo grated with its skin on, the entire hot pot is uniformly brown, leading some to call it 'Japan's least photogenic hot pot.' However, it was not the visual appeal but the gently rich and flavorful taste, recognizable with a single bite, that was highly praised by the 220,000 visitors, leading to this achievement.

- Before cooking.
- As it cooks, and when grated Jinenjo is added as a finish, the entire pot turns uniformly brown.

### ■Coming to supermarkets nationwide this autumn! Collaboration with Daisho Co., Ltd. decided
Following this Grand Prix award, Daisho Co., Ltd., a major seasoning manufacturer and sponsor, has decided to release a 'hot pot soup' that recreates this menu. It is scheduled to be released sequentially at supermarkets nationwide from autumn 2026. Joint development is currently underway to meet the expectations of fans who wish to 'enjoy Japan's best taste at home.'

Chef Ryota Tajima: "Please enjoy the taste of our specialty restaurant at home. A confidently recreated masterpiece with 100% authenticity!! We focused on a soup that is gentle yet profoundly flavorful."

### ■A hidden urban oasis where 'Welcome Home' resonates with warmth
The interior of the new store incorporates 'old wood' recycled from old Japanese houses and 'cedar scaffolding boards' actually used at construction sites. With dried flowers placed throughout, it creates a stylish yet nostalgic and calming space.

Staff uniforms feature 'kappogi' (a type of apron) from Nakagawa Masashichi Shoten, a long-established store founded in Kyoho 1 (1716). When welcoming customers, we say 'Okaerinasai' (Welcome Home) instead of 'Irasshaimase' (Welcome). You can enjoy our special yam dishes in a sense of security, as if you've returned home, forgetting the hustle and bustle of the city.

- A nostalgic atmosphere adorned with dried flowers.
- Staff in kappogi provide hospitality.
- Pillars made from old wood
- Carefully selected lighting fixtures
- Yam art by chalk artist 'MIKI'
