A long-term back injury ruled Obano out of the 2014 Junior World Cup.[1] In December 2017, Obano received his first England call up for the 34 man Six Nations training squad. He was called up for the Summer tour to South Africa in 2018 but was injured during camp. He played against Barbarians in summer 2019.[3]
Obano received his first England cap during the opening round of the 2021 Six Nations Championship in their 6-11 loss to Scotland.[4]
On the 17th January 2024, Obano was called up to the 2024 Six Nations Championship for England. He was announced on the bench after Ellis Genge pulled out with a foot injury, just before England's Round 1 game against Italy. He came on in the second half, receiving his 4th cap.
