Koi-no-mikoto is not a widely documented figure in mainstream Shinto or Buddhist tradition, and no established shrine records, classical texts, or canonical mythology appear to reference a deity by this name. The name itself suggests an association with love or romantic affection, as 'koi' can mean 'love' in Japanese, but this appears to be a modern, folk, or invented designation rather than a historically attested kami. Those interested in traditional Japanese deities connected to love and relationships might instead look to figures such as Izanami and Izanagi or shrines like Izumo Taisha, which have documented associations with matchmaking and marital bonds.
