[Enjoy Premium Block Meat at Home] 'MOTTAINAI BEEF', Winner of the Best Mail-Order Grand Prize, Launches 'Japanese Black Beef Selected Lean Meat Block' with Luxurious 'Moderate Marbling' Texture on June 4 (Thu) at 8 PM

MOTTAINAI BEEF, a sustainable D2C brand operated by OMI Co., Ltd. (Headquarters: Minato-ku, Tokyo; President: Masahiro Omi), which utilizes non-standard and unused cuts of Japanese Wagyu and domestic beef, will begin selling a new product, the 'Japanese Black Beef Selected Lean Meat Block (300g)', starting today, June 4, 2026 (Thursday) at 20:00, in limited quantities on its official online store.

■ Background of Development: 'Lean Meat Block' Born from Customer Requests for 'Something Like This!'

MOTTAINAI BEEF, which has won the 'Best Mail-Order Grand Prize 2025 Overall Grand Prize' and the 'Social Products Award 2026', has been well-received by many customers.

While the brand has primarily focused on yakiniku (grilled meat) cuts, trimmings, and processed products, the most passionate request from customers was for 'luxurious block meat to enjoy at home'.

'I want to make a perfect roast beef at home.'

'I want to enjoy a premium steak cut to my preferred thickness.'

To answer these requests, the company leveraged its professional expertise as a Wagyu specialty wholesaler with over 60 years of history to develop a lean meat block product using the highest quality Japanese Black Beef.

■ Product Features: 'Moderate Marbling' Softness Defies the Common Belief that 'Lean Meat is Tough and Hard to Cook'

Generally, there is a perception that 'lean block meat tends to become dry and tough when cooked at home.'

To dispel this concern, this product exclusively uses rare cuts from Japanese Black Beef, such as 'Uchimomo' (inside round) and 'Shintama' (knuckle), which have particularly uniform and tender fibers among lean meats.

Professional craftsmen carefully select only the highest quality portions from the blocks produced when preparing premium Japanese Black Beef, typically supplied to top-class hotels and the Imperial Household Agency.

Because the meat is in a 'moderate marbling' state, characteristic of high-quality Japanese Black Beef, with fine and appropriate fat content, customers can enjoy the rich, direct flavor of the lean meat while experiencing a moist, juicy, and surprisingly tender texture.

■ Easy 'Premium Meat Bistro' at Home: A Foolproof 300g Size for Beginners

This product focuses on the '300g' size, which is ideal for residual heat cooking using a home frying pan and aluminum foil.

Since it is easy to manage the internal temperature, even beginners can successfully achieve a 'crispy exterior and a beautiful pink rare interior' without special equipment.

Depending on the seasoning and arrangement, you can easily create professional-level dishes at home.

'Easy Tagliata at Home'

Italian-style 'Tagliata'

Simply sear the meat, slice it thinly, and serve with arugula and shaved Parmesan cheese, drizzled with balsamic vinegar and olive oil.

A stylish dish perfect for a weekend wine accompaniment.

'Tartare-style Wagyu Tataki'

Quickly sear the surface, chop it finely while still rare, and mix with onions and aromatic vegetables. The sweetness of the Wagyu fat and the umami of the lean meat stand out, creating an irresistible dish.

'Refreshing Wagyu Tataki'

Please enjoy the overwhelming meat juices sealed within the block and the rich flavor of Wagyu that fills your mouth with every bite, in your preferred style.

■ 'Democratization of Wagyu' as MOTTAINAI BEEF's Goal

Our company has been a beef wholesaler for over 60 years, supplying selected Wagyu and domestic beef to famous hotels and the Imperial Household Agency.

We purchase and process whole cattle. However, in manufacturing products for wholesale, there is a significant amount of 'mottainai' (wasteful) beef that becomes food loss due to trimmings for shaping or slight deviations from specifications.

We named this beef 'MOTTAINAI BEEF' and began selling it as a sustainable food source, maintaining assured quality so that more people can enjoy it.

With the concept of 'Democratization of Wagyu', we aim to deliver the Wagyu carefully raised by producers without waste to the daily tables of as many people as possible.

[Awards]

The assured quality and socially meaningful concept have been recognized with prestigious awards from Japan's largest mail-order information site.

● 'Best Mail-Order Grand Prize 2025' Overall Grand Prize / Imperfect & Trial Category Gold Award

● 'Best Mail-Order Grand Prize 2024' Meat Gourmet Category Gold Award
