KAGRA is a kilometer-scale gravitational wave (GW) detector situated underground in Kamioka, Japan. The Japanese archipelago is known for its seismic activity, posing a challenge to GW observations and its detector commissioning. This presentation will cover the following topics: (1) seismic motion from earthquakes at the KAGRA site, (2) the impact of earthquakes on the O4a observation conducted in May/June 2023, and (3) the effects of the Noto earthquakes in January 2024.
