The outbreak of COVID-19 in Indonesia brings larger-scale social restriction, impacting educational institutes in carrying learning activities. Recent trends in Japanese language learning research in vocational training institutes lean toward the learning style before the pandemic, which is heavily oriented to support face-to-face meetings. Topic about how vocational training institutes conduct learning activities as an adjustment to the pandemic is not yet broadly examined. This article aims to examine the implementation of Japanese Language online learning for the engineers in a vocational training institute LPK Mulia Meisou Indonesia Bandung (LPK MMI), which focuses on 1) how online learning is being implemented in this institute and 2) how the students respond the implementation of this online learning. Through the teacher's note and student's survey from LPK MMI's Engineer Special Class. The findings showed that it was possible to establish a simple online learning management system and implement synchronous and asynchronous learning by utilizing the bare minimum application and free platforms such as LINE, Whatsapp, and Google Classroom. The students perceived that utilizing those applications as online learning tools was somewhat sufficient to help them study at home. There was interest in alternative applications such as Zoom, Google Meet, Wideboard, or Microsoft Teams to be implemented as online learning tools. However, there were also concerns regarding these tools to be useful when the cellular signal was unstable and cellular data also limited. Thus, utilizing the most common application for both students and teachers and utilizing the free platform could be a good option for conducting online learning for those who have limited resources.
