Carvalho lives up to the hype for UH
With 21-mph quickness, Hawaii slotback Kainoa “Kaikai” Carvalho jets through pass routes at the speed of blur.
With 21-mph quickness, Hawaii slotback Kainoa “Kaikai” Carvalho jets through pass routes at the speed of blur.
Carvalho showed that against Stanford, turning five catches into 72 yards this past Saturday.
But Carvalho also has demonstrated patience and perseverance in following an extended route to becoming a trusted Rainbow Warrior receiver.
As a Kahuku High School junior in 2021, Carvalho was named the Honolulu Star-Advertiser’s Offensive Player of the Year. He also earned KHON Cover-2’s first Marcus Mariota Award as the state’s most valuable player. That season, he caught 64 passes for 1,023 yards and 10 touchdowns. He averaged 9.2 yards on end-around runs and jet sweeps. He scored on three kickoffs and two punt returns. And he converted on 45 point-after kicks and two field goals.
But his future pledge to play for the University of Utah was put on pause. He had made a greater commitment to serve a two-year church mission following his Kahuku graduation on May 18, 2023. He earned money for the mission working summer construction jobs in Utah.
“I was born and raised in the (Mormon) church,” Carvalho said. “I had a lot of great influences. My dad went on a mission. He would always tell me stories about it. Just growing up, and sharing that love and light to everyone else, I felt obligated to serve the Lord. And that’s why I went on a mission.”
His preferred assignment to Japan was granted. His mother grew up in Japan. “My mom only spoke Japanese to me when I was little,” Carvalho recalled.
His father Stew Carvalho, a former Utah player, has a business that requires frequently traveling to Japan.
The mission would be challenging. According to a 2023 survey by the Department of Religious Affairs of the Ministry of Culture of Japan, there were 300,921 Christians in Japan (or 0.73.% of the country’s population).
“There’s not a lot of Christian background over there,” Carvalho said. “There’s a lot of Buddhists or no religion. For me, it was just to be an example, to serve them in whatever they needed. Not to force them but be the light and example.”
With dawn-to-dusk ministry, Carvalho managed to find time for fitness. He bought dumbbells, as well as a weight bench. “I made sure to get in something every day, whether it’s calisthenics or lifting.”
In spreading the Gospel, he averaged 10,000 steps a day. “Biked miles and miles in the summer,” he said. “Got a lot of steps in, a lot of cardio from biking.”

Once a week, he was allowed phone and computer privileges to communicate with family and friends. Because national letters of intent are binding for only a year, UH receivers coach Jared Ursua eventually was able to make pitches to Carvalho. John Ursua, Jared’s younger brother and a former UH and NFL receiver, had trained with Carvalho under Kawe Johnson.
“Coach JU was amazing in staying in touch with me,” Carvalho said. “He served a mission. He knows what it’s like to be away.”
With the shuffling of Utah’s coaching staff after the 2024 season, Carvalho opted to explore other post-mission destinations.
Jared Ursua asked Carvalho: “What other place do you want to be when you come home?”
After consulting with his parents and mentors, Carvalho accepted UH’s offer.
“I was already coming home to Hawaii,” Carvalho said. “I just felt it was a sign to come home and play for this state.”
Carvalho completed his mission in May 2025. He enrolled in UH’s 2025 bridge program — two three-credit summer courses — while joining the offseason conditioning program and player-run practices.
He spent the 2025 season shadowing slotbacks Pofele Ashlock and Nick Cenacle. Ashlock is recovering from an injury, and Cenacle has moved on to the Canadian Football League.
“They were great mentors,” Carvalho said of UH’s two leading receivers in 2025. “Just seeing those guys have success brought me happiness. And now I want to repay them for all they taught me. I want to apply what I learned.”
Size is not an issue for Carvalho, who relies on quickness, precise patterns, and sure hands.
“People say I’m 5-6,” Carvalho said. “But I like to say I’m 5-7 … with cleats on, and the helmet on, and if I stand up straight.”
He weighed 171 pounds when he returned from his mission. “So much rice up there (in Japan), and ramen, and meat,” said Carvalho, who now weighs 165.
A few years ago, Ursua recalled, “I saw our offense trending back to the run-and-shoot. I thought this kid would be perfect for us. He is.”
