Which universities in Japan have doctoral degrees in library science? Besides Tsukuba and Keio, what else?
And ... However, I suggest you go to Keio or Tsukuba. Since I am a doctoral student, the research atmosphere is very important. You can learn a lot by studying library teachers and studying more topics. A private person, a country. Keio is famous, but the tuition is expensive. Some teachers in Tsukuba graduated from Keio University. Rigorous in scholarship.
