This presentation introduces a pedagogical project aimed at igniting Japanese university English learners' willingness to communicate by providing an authentic communication experience from the everyday English classroom. The designed project consisted of three discovery missions for students that began when students received a box from overseas. By writing a letter and receiving a response, students created a presentation on what they learned about the sender. This pedagogically designed experience-based activity fostered an interest in communicating with dissimilar others using English as a communication tool. This project contributes one idea for practitioners who wish to incorporate authentic communication in their everyday lessons.
