Suntory and Kimi no Na wa collaborated on ads. The character Mitsuha Miyamizu is shown drinking SUNTORY Minami Alps Tennensui Yogurina, which is yogurt-flavored mineral water, in the ad "Mitsuha no Omoi" (Mitsuha's Thoughts). Taki Tachibana is shown in the "Taki no Omoi" (Taki's Thoughts) ad sipping SUNTORY Minami Alps Ten'nensui mineral water. Taki and Mitsuha combine their ideas in the "Kasanaru Omoi" (Overlap Thoughts) ad, which has mixed speech, alternate footage, and a new tune.
