To understand the interaction between solar wind and lunar magnetic anomalies, low energy electrons and ions over lunar magnetic anomalies were simultaneously observed for the first time by the "Kaguya" satellite. This paper discusses the plasma structure over the mini-magnetosphere. The observations clearly showed acceleration of electrons and deceleration of ions and suggested the existence of a non-adiabatic dissipative interaction between solar wind ions and lunar magnetic anomalies. Since the interaction between solar wind and lunar magnetic anomalies occurs on the smallest scale of its kind, it contributes to the understanding of the interaction between solar wind and magnetized airless bodies in space. This is one of the most significant achievements of the Japanese spacecraft mission "Kaguya". These observations have been cited by many studies dealing with solar wind-lunar magnetic anomalies interactions.

Tsunami source of the 2011 off the Pacific coast of Tohoku Earthquake
Yushiro Fujii, Kenji Satake, Shin’ichi Sakai, Masanao Shinohara, and Toshihiko Kanazawa
This paper compiled the Tsunami waveform data from tide gauges, GPS wave gauges, and ocean bottom pressure gauges associated with the 2011 Tohoku Earthquake. From the waveform inversion, the authors successfully explained the two-step waveforms, which were the most outstanding characters of the data. First, to explain the initial rise in water level, the slip on the plate interface was estimated at the southern Sanriku and Miyagi-oki, around the epicenter. Second, to explain the later impulsive waveform, a large slip of around 40 m was modeled along the trench axis. This timely publication, as a contribution to the special issue of “First Results of the 2011 Off the Pacific Coast of Tohoku Earthquake”, provided a standard model for the study of the 2011 Tohoku earthquake. As such, this paper has received a large number of citations and is therefore well-deserved of the EPS Excellent Paper Award 2016.
