NRI partnered with Koto-ku, Tokyo-headquartered BIPROGY Inc.. (BIPROGY) to jointly develop BANKSTAR®, an accounting system for the banking industry.

BANKSTAR® is an open accounting system that Nihon Unisys developed for banks that have no physical branches.

When deploying BANKSTAR® at client sites, NRI handles application development and Nihon Unisys is responsible for constructing the platform.


BANKSTAR® is primarily designed to address the needs of banks with no branches.
