Authored Works

sorted by decreasing year, and then by display-name

• Small lunar craters around the rim of Shackleton crater at the lunar South Pole: Spatial distribution and size-frequency
• Small craters on the nearside of Phobos: Morphology and degradation
• CNN-based Automatic Identification of Rock Particles on Small Bodies
• We performed crater size-frequency measurement on Ryugu using high-resolution images obtained by Hayabusa2. Using Ryugu cratering chronology model, the surface age of Ryugu was estimated to be 0.1 to 1 billion years from the density of craters larger than 100 m in diameter.
• Preliminary geomorphological map of asteroid Ryugu
• Global distribution of lineaments on Ryugu
• Geology on asteroid Ryugu revealed by Hayabusa2 visible multi-band imaging observations
• Distribution and morphology of craters on asteroid Ryugu
• Characteristics of spatial distribution of boulders on Ryugu
• Hydrological Process of Martian Surface in Hesperian epoch
• Cross-stratified Pyroclasts: Do They Represent Primary Deposition by Pyroclastic Flow or Reworking by Oceanic Process?
• Giant Subaqueous Pyroclastic-Flow Deposits Revealed: Sedimentological Revision of the Holocene Outcrops of Izu-Oshima Island, Japan
• Centimeter-High Antidunes within Pyroclastic Deposits: Are They Products of Surge or Density Current?
