I am a climate scientist, focused on paleoclimate, sea level change and the evolution of Quaternary glaciations.
I reconstruct ice sheets using glacial isostatic adjustment, as well as ice sheet modelling. In Japan but have been pretty much everywhere.

Sakai et al present a speleothem record from the Middle Pleistocene from Nara, Japan. The speleothem is at least 460 thousand years old. A more precise age is not possible to deduce, since it is at the limit of the U-Th dating method. ⚒️🧪🌊 geoscienceletters.springeropen.com/articles/10....
A snapshot of the climate in the Middle Pleistocene inferred from a stalagmite from central Japan - Geoscience Letters
Stalagmites are useful archives in reconstructing paleoclimates: most paleoclimate studies used stalagmites that are distributed in specific locations and ages. We examined a stalagmite (GYM-1) collec...
The inferred temperatures suggest it did form during an interglacial period. Speleothem records in Japan are not common, so it is good to see that work is being done to collect them.
