ONE OK ROCK signed with Universal Music in the US, and released an English edition of 35xxxv in February 2015. In 2016 the group would move over the popular punk-rock indie label Fueled By Ramen.
In 2017, Taka was one of many international musicians and celebrities featured in the self-directed music video for British singer Charli XCX's single "Boys". The video featured other Asian artists such as Jay Park and EXILE SHOKICHI.
