What is T2R2?


Tokyo Tech Research Repository (T2R2) is designed to provide a unified system of data storage, management and dissemination for academic papers and books published by researchers of Tokyo Tech. T2R2 is one of the pillars of Tokyo Tech STAR, which aims for the systematic storage and transmission of knowledge sources produced through education and research activities at Tokyo Tech.

T2R2 Architecture


The T2R2 system provides functions for registering, storing, and disclosing meta-data (bibliography information) and PDF files of academic publications written by all researchers of Tokyo Tech.

Academic papers and books registered in the T2R2 system can be searched and read widely by users both in and outside the campus using the T2R2 open search service. Academic achievement data from the Researcher Information System can also be used in the T2R2 system.

Although T2R2 requires users to register the data themselves, the system provides input support functions, which can reduce the labor costs of data registration, as well as various output types for multipurpose applications, to enable use as a data management system.

  • Academic achievement data registered in the Research Information System have been transferred to the T2R2 system.
