Joji collaborated with Johnnie Walker to create 'The Honeycomb Highball Cocktail Kit' in September 2020. This kit was inspired by his album 'Nectar' and included Johnnie Walker Black Label, a custom-engraved Joji x Johnnie Walker bar spoon, and Joji's own Nectar, offering a new take on the classic highball.

Joji released the song 'Joji' as part of a Toyota Corolla Series TV commercial in June 2025. The song was streamed in advance on June 11, 2025, ahead of his album 'Aeka' release in July.
