Honoring Heritage Through Innovation: How Kyu Utsunomiya Brings Japanese Cuisine to Life in Arizona
Conceptually Social’s Kyu Utsunomiya
When Kyu Utsunomiya moved from Chicago to Arizona in the late 1980s, Japanese food was a rarity in the Valley. He quickly noticed how little of the cuisine he grew up with was represented here — and how much opportunity there was to share his heritage in meaningful, modern ways.
“There were only a few places back then,” he says. “Now sushi is everywhere. It’s great to see the demand grow — but even better to be part of that growth.”
As co-founder of Conceptually Social, a culinary collective and catering company, Utsunomiya has helped launch and operate multiple restaurants across the Valley. But none reflects his roots quite like Kaizen, his flagship sushi concept.

Named for the Japanese principle of “constant movement and improvement,” Kaizen was born during a moment of uncertainty — early 2020, when Utsunomiya and his business partner had just opened The Larry in downtown Phoenix.
When the pandemic hit, they pivoted fast. “We leaned into a sushi idea we’d been tossing around,” he says. “It was personal for me. It was a way to honor my father, and to bring something authentic to Arizona’s food scene.”
Drawing on his cultural background and values of adaptability and perseverance, Utsunomiya transformed their catering vehicles into sushi delivery trucks. “We were driving across the Valley, delivering elevated sushi to people’s doors. We had to make it work — and we did.”

Kaizen gained traction, eventually landing a spot at State Farm Stadium, where it brought Japanese cuisine to thousands of football fans.
That community support hasn’t gone unnoticed. “The Valley embraced us,” Utsunomiya says. “We’re lucky to be part of this community — and that drives us to keep evolving.”
From exclusive catering and event venue management to creating neighborhood restaurants and coffee shops, Utsunomiya and the Conceptually Social team strive to create and foster spaces for the community to gather and enjoy exceptional food and drink.
Now, as they plan a permanent Kaizen reopening in 2026, Utsunomiya is also introducing Konbini Sushi — a new fast-casual concept inspired by the grab-and-go culture of Japanese convenience stores. The first Konbini counter recently opened inside Silo, a Conceptually Social restaurant in Tempe. The team has also partnered with Phoenix Museum of Art on a new restaurant concept, Alden. Set to open in late Spring, Alden’s menu will reflect the global influences and cultures that have shaped Phoenix.

Beyond the food, Utsunomiya is deeply intentional about how his business shows up in the community. As a 100% locally owned and operated company, Conceptually Social emphasizes sustainability, ethical practices and alignment with mission-driven organizations.
Under Utsunomiya’s leadership, the team partners regularly with local nonprofits and community agencies whose values reflect their own. They donate surplus food from canceled events to St. Vincent de Paul, recycle used cooking oil into biodiesel and proudly participate in the City of Phoenix’s Green Business Leader program.
For Utsunomiya, these efforts are another way of honoring the principles he was raised with: care for others, respect for resources and commitment to community.
Through each venture, Utsunomiya’s heritage remains a grounding force. “Japanese culture is all about precision, balance and hospitality,” he says. “That’s the thread that runs through everything we do. It’s not just about sushi — it’s about sharing who I am.”
