Wagyu Mafia of DMV — 和牛マフィア
How Chef Junzo Miyajima and the IVEA team expanded access to Wagyu across the Washington, Maryland and Virginia region through supplier relationships, purchasing volume, in-house cutting and all-you-can-eat dining.

For many diners, Wagyu has been something to save for a special occasion. A small portion could take up a large part of the dinner budget, making it difficult to imagine ordering it regularly or sharing it with the whole family.
Chef Junzo Miyajima and the IVEA team wanted to change that.
Through their work across Gyu Shige, Gyusan, Gyuzo and Genki Wagyu House (Genki Wagyu Shabu House) in Rockville, MD, they helped expand the ways people in the Washington, Maryland and Virginia region could enjoy Wagyu. Alongside developing the food, the team worked on where the beef came from, how much they purchased, how they prepared it and how they priced the meal.
How the team brought Wagyu within reach
Their approach combined supplier relationships, buying volume across multiple restaurants, in-house cutting and all-you-can-eat dining. Together, those decisions helped the team bring prices within reach of more guests.
Junzo brought the culinary experience to support that ambition. Born in Saitama Prefecture, Japan, he has more than 20 years of experience as a chef. Gyusan identifies him as IVEA's corporate chef and credits him with developing three Japanese barbecue restaurants in the DMV.
Working across several restaurants gave the team purchasing volume beyond a single dining room. Supplier relationships supported that buying effort, while in-house cutting gave the kitchens more control over preparing the beef. The all-you-can-eat model brought those efforts together in an offer guests could understand: choose a course, know its price and enjoy the selections included.
Four brands, one vision
Each restaurant gave that approach its own expression. Gyu Shige brought Japanese barbecue to Fairfax's Mosaic District. Gyuzo offered another yakiniku destination in Rockville. Gyusan expanded the choices with all-you-can-eat Japanese barbecue and sushi in Arlington and Columbia.
At Genki Wagyu Shabu House in Rockville, the experience centers on thin slices of beef cooked in hot broth at the table. Its menu makes the range of choices concrete.
Menu and pricing at Genki Wagyu Shabu House
The $58 Silver dinner includes American Wagyu toro belly. The $78 Gold course adds Australian Wagyu selections and one order of Japanese A5 shoulder per person. At $98, Diamond includes unlimited Japanese A5 brisket and shoulder, plus one order of A5 chuck ribeye per person. Dining sessions last 90 minutes, and everyone at the table selects the same course.
American, Australian and Japanese Wagyu offer different experiences, and the menu identifies those differences. Guests can choose according to what they want to try and what they want to spend.
Planning your visit
For DMV diners, that choice is the benefit. Friends can plan a Wagyu dinner around a stated course price. Someone trying it for the first time can select a starting point. A family can compare the options before deciding where to gather.
Wagyu remains a meaningful dining expense. Junzo and the team's ambition is to make it possible for more people to enjoy it, more often. That takes attention to purchasing, preparation and the value guests receive when they sit down.
Across these restaurants, the team has connected that work to a shared experience: people gathering around a grill or a simmering pot, cooking together and sharing a meal.
