This study reports on a project-based class involving volunteers and international students, exploring through feedback what factors helped participants work collaboratively. The study aims to help to transforming the Japanese language classroom into a space that encourages learning for both volunteers and international students in a mutually beneficial way. The feedback is a self-assessment of their collaborative work, as well as an evaluation of five suggested factors that contributed to their participation. Both students and volunteers found it helpful to have 'a space and time to talk freely', 'enjoyment', and their 'proactive attitude' to enhance their collaborative activities. This finding provides teachers with insight, which is beneficial in allowing participants some freedom in terms of time and space, when planning international collaborative projects.
