Koi Nikki is a Japanese online dating and matchmaking service operated by Regista Co., Ltd. Designed to help people find friends, romantic partners, and companions, the platform offers a private space for members to connect and communicate through a smartphone. The service promotes an easy-to-use experience for newcomers and provides email notifications for registered members.

Membership is restricted to people aged 18 or older, with age verification required; the site also states that students may not use the service. Registration itself has no fee, monthly charge, or withdrawal fee. Instead, members purchase points, which are used for selected communication features. Purchased points expire 180 days after the most recent purchase, and paid charges are generally non-refundable.

Koi Nikki identifies itself as a notified internet dating service and publishes terms of use, privacy information, and youth-protection policies. The company says personal information is handled under its privacy policy, while card payments are processed through Albatal Pay. The service is intended for member-to-member communication and prohibits unlawful, commercial, and exploitative activity.
