Joy is a casual group matching app that allows users to participate in casual gatherings and events, such as gal drinking parties and mixers, with multiple people in just 30 minutes. It is ideal for those looking to easily explore romantic opportunities and socialize in Tokyo.

With Joy, users can easily organize group events by selecting the "Host a Mixer" option from the app, setting the date, location, number of participants, and duration. They can also provide details about the event to attract like-minded individuals.

To join ongoing mixers, users can browse through suitable events based on date, purpose, and location, and select the ones that interest them. Once chosen, they can seamlessly enter the mixer and engage in chat conversations exclusively with other confirmed attendees for a safe and secure interaction experience.
