The KamLAND experiment began observations in 2002 and concluded on August 27, 2024. Please visit this page to learn more about our achievements. Since then, we have continued our research to enhance detector performance and have been planning the next-generation experiment, KamLAND2. On this page, we introduce our journey from the shutdown of the KamLAND detector to the launch of KamLAND2.
