What are Doctoral Dissertations?

Doctoral dissertations are academic theses.
There are two kinds of dissertations:

  • Dissertation Ph.D. Course: A submitted dissertation, required to finish a doctoral course.
  • Dissertation Ph.D.: A submitted dissertation, required to obtain a Ph.D. degree without having to enroll in a doctoral course.
Some dissertations are available electronically on the Internet. In principle, Japanese doctoral dissertations submitted after April 1st, 2013 should be published online.

Find Masters Theses

There is no facility that stores all master's theses collectively because the obligations of public presentation or legal deposit of books to the National Diet Library are not imposed, unlike doctoral dissertations. Moreover, there is also no comprehensive database. Since storage situations differ for every university, please confirm availability using the website of the relevant college library.

Master’s theses are not stored in the University Library for Agricultural and Life Sciences. Please enquire at the relevant laboratory.
For the storage situation of other graduate courses’ master’s theses, confirm using the "doctoral dissertations holdings and usage guide."
