Chemical compositions and/or flux of volcanic gases reflect conditions of magma activity or hydrothermal system beneath the volcano. Monitoring of volcanic gases is therefore an important research target to understand the conditions of volcanic acitivities. So far, my work has been focused on developing and establishing new techniques for monitoring volcanic gas.

The main target of our group is to understand the degassing processes in magma and the mechanism of eruption based on observational reseach works on volcanic gas emissions.
