Objectives
Based on discussions in the Science Advisory Committee, the National Astronomical Observatory (NAOJ) held the 'NAOJ Future Planning Symposium 2021: Thinking about Future Plans Across Wavelengths' in November 2021 to discuss science in the various fields of astronomy, and the 'NAOJ Future Planning Symposium 2022: How to decide and promote future plans' in December 2022 to discuss the framework how future plans at NAOJ should be planned. As a result, it was broadly agreed that NAOJ’s future plan should be developed in the following three steps:
