The number of detected exoplanets has been increasing thanks to Kepler and TESS. So far, we have learned of the diversity of exoplanets ranging from Super-Earth- to Jupiter-size. Among them, some are thought to be rocky planets within the so-called habitable zone. Thanks to the successful launch of the James Webb Space Telescope (JWST) in 2021, exoplanetary science is opening a new era for the characterization of the exoplanet atmosphere. Various next projects are underway, such as Ariel and JASMINE space telescopes and TMT. A new generation of exoplanetary science will be not only a field of astronomy but also Earth-Planetary Science. Thus, we must have a comprehensive discussion based on various science backgrounds, such as stellar physics, disk evolution, planetary formation, and planetary climate. This session aims at allowing participants to share their knowledge and research results, inform the current status of each project of exoplanets, and discuss future prospects in the field of exoplanetary science from both theoretical and observational points of view. We welcome participants from various fields of science and young researchers.
