Young plutons of 10-0.8 Ma, including the world's youngest Kurobegawa pluton, are exposed in the Kurobe area of the Hida Range, central Japan, indicating rapid rock uplift and exhumation in the Quaternary. However, reconstructing the exhumation history has been challenging because interpretations of the thermochronologic data are difficult due to the complicated, recent and active thermal history/structure. Here we are determining the exhumation history by estimating formation depths and ages of the young plutons based on Al-in-Hb geobarometry and zircon U-Pb geochronometry, respectively. At JpGU2021, we reported the preliminary results based on three datapoints from the ~5 Ma plutons and one datum from the ~0.8 Ma pluton, suggesting the three following interpretations: (1) formation depths of ~5 Ma and ~0.8 Ma plutons were estimated to be ~6-9 km, which indicates an increase of the exhumation rate after ~0.8 Ma, (2) mean exhumation rate since ~0.8 Ma was computed at 8-10 mm/yr in the Baba-dani area, (3) the formation depths are uniform in the E-W direction, disagreeing with the eastward tilting model. As of January 2022, we have obtained 14 datapoints in total: five from the ~5 Ma plutons, two from the ~2-1 Ma plutons, five from the ~0.8 Ma plutons, and two from the 
65 Ma plutons. These additional data are basically consistent with the previous data, reinforcing the three interpretations above. Recently, new uplift models of the Kurobe area were proposed, in addition to the eastward tilting model. Ito et al. (2021) suggested that the Kurobegawa pluton is a resurgent pluton of the Jiigatake caldera and was uplifted by the resurgence. Kawasaki (2021) proposed that displacements related to the E-W compression are localized along the Kurobe area due to the high geothermal gradient caused by presence of thermal fluid interstratified layers. We are planning to discuss consistency between our data and these two models.
