We study the earth from viewpoints of climate, water, and isotopes to make a contribution to understanding of climate system and prevention of water-related disasters.

Where we areY-Lab is located in the Chiba Experiment Station of Institute of Industrial Science in Kashiwa campus.

Open CampusVisualization of water cycle with spherical display helps visitors understand research topics.

OfficeBig windows help to get a lot of sunshine and make the officecomfortable.

Isotope Experiment RoomY-lab is fully equipped withexperimental instruments includingmass and laser spectrometers.

Reception SpaceLab members often take a rest and chat with others here.

What we do

Field SurveyWe sometimes conduct a field survey for better understanding of local conditions.

Many Lab MembersCommunication and discussion with lab members are driving force of Y-Lab.

Provision of useful information for climate change through understanding climate system using model development and its application
