Virtual exchanges (VEs) provide opportunities for authentic communication and intercultural learning, yet real-world implementation often involves unexpected challenges. This presentation examines three cases of productive failure across different contexts. The first case involved two classes of 25 Japanese university students (A2–B1) paired with classes of approximately 50 students in Spain and Türkiye (B2–C1). A substantial proficiency mismatch required strategic grouping, task reframing, and expectation management to maintain engagement. The second case connected 220 Japanese students with 180 Korean students (A2–B1) in a large-scale VE. Despite detailed planning, technical problems and inconsistent partner procedures disrupted activities, underscoring the importance of deliberately simple platforms and task designs. The third case concerned a Kaken grant-funded VE with a Korean university that collapsed shortly before launch. Rapid redesign and the use of alternative VE resources enabled students to complete meaningful activities despite the cancellation. Across these cases, each setback offered clear reasons to terminate the exchange, yet quick decision-making and reflective redesign led to more resilient systems. The presentation concludes with practical strategies that other instructors can adapt to strengthen their own VEs and, ideally, inspiration to develop creative solutions when facing their own unexpected difficulties.
