We have the greatest domestic market share in the number of local governments employing e-CLEAR sewer user fee system whose number amounts to 256 governments throughout Japan.


We have expanded our “e-CLEAR” series as our package system for business use designed for local governments throughout Japan. Among them, our “sewer user fee system” has the greatest domestic market share. This system has been used for calculating and collecting obligation fees for local residents to pay for the construction cost of sewage improvement. It has won popularity not only in its flexible system with many parameter settings enabling management of various ordinances, administrative executions, and regulations enforced in the local governments throughout Japan, but also in its capacity to manage basic data, arbitration, collecting fee, and absence of payment in an integrated manner in one single system. We will continue to improve our customer satisfaction and increase in the market share by providing our customers with value-added systems meeting customer needs in niche markets.
