Business Areas

From breeding technology to the finished dish

From upstream breeding technology to a dish on the table. The numbers follow the order of the value chain — each area is the raw material for the next.

Analytics · Herd management · Feed design · Premix

After blood sampling, AI quantitative evaluation assesses seven carcass quality indicators, moving the evaluation point forward by about 18 months; on this basis we design koji-mold fermented feed and an in-house premix, and transfer herd management technology to partner farms.

Chilled Wagyu Wholesale

Chilled wagyu wholesale

About 100 head of Wagyu processed each week, chilled at 0–4℃ throughout and never frozen, supplied to Japanese, Western and Chinese restaurants. Chilled is the mainstream form for premium beef in Japan and overseas.

Koji Fermentation & Aging

Koji Fermentation & Aging

Koji fermentation & dry aging

21-day koji-mold aging. Its lineage traces back to the Ming-dynasty Bencao Gangmu and the Edo-period Hikone Domain's miso-cured beef "Hanpongan" — a three-hundred-year-old thread reconstructed with modern methods.

Sous-vide · black-pepper Wagyu

Sous-vide

Sous-vide · SASHIMEAT

Prepared Dishes (Sozai)

Prepared side dishes

Japanese-style side dishes such as shigure-ni, tsukudani, kinpira and croquettes — simply reheat and serve. Bringing our upstream meat-quality advantage to bento boxes and everyday tables.

Brand · KOJI-BEEF
Flowers on rice,
koji awakens the meat

"Koji Beef is Wagyu raised on feed fermented with koji mold (Aspergillus oryzae), the same strain used for Japanese sake — light on the palate, clean and never heavy, melting in the mouth. Kept chilled at 0–4℃ throughout, never frozen."

One strain of koji mold runs through the entire chain — the koji in the feed and the koji in the aging come from the same mold.Brand Story →

Why Majime Food

Why Majime Food

Three reasons
01

Wagyu, Quantified

Blood sampling at 12 months and AI scoring of seven carcass quality indicators turn "good meat" from intuition into predictable data — we know what the meat will become while the animal is still alive.

02

One Koji, the Whole Chain

The koji in the feed and the koji in the aging room are the same strain: from feed design, fattening and chilled fabrication to aging, sous-vide, prepared dishes and pet food, six domains link end to end under our own control.

03

Japanese Standards, Made in China

Japanese Wagyu breeding philosophy and fabrication standards, implemented at our partner ranch in Shandong and our Shanghai studio; a Meat Meister Grade 1 representative personally oversees quality, with a steady supply of about 100 head per week.

Founder
"Wagyu should not rely on intuition alone. Turning breeding, feed and aging into science that can be explained and reproduced — that is why Majime Food exists."
