Tokyo University of Science has an advisor system for newly admitted international students in the department that covers their first half year of study. Advisors are graduate students currently enrolled at TUS who can discuss your studies, life at the university, or help with any other questions you may have. Many advisors will also assist you as you make your transition to life in Japan. They can help you with Japanese customs and social conventions, and in many instances your advisor will be one of the first friends you make in Japan. Even if you have no questions in particular, it would be best to meet once a week just to report on your current situation.
