NTT DATA Corporation

NTT DATA Corporation (hereinafter:NTT DATA) will begin offering the document management solution “Prexifort-OCR® e-Document Plus” starting from May 1, 2016. In response to the relaxation of the requirements of the Electronic Books Maintenance Act*1 in 2015, this document management solution assists the registration, preservation, and utilization of national tax-related documents (contracts, bills, estimates, etc.) that need to be kept for a long time.

Features of “Prexifort-OCR e-Document Plus” include keyword extraction OCR*2 for automatically acquiring a search keyword from non-formalized forms, a time stamp*3, multi-condition search of stored documents, user management, and acquisition of operation logs. With the assistance of these features, clients can reduce document preservation costs, streamline document search, and promote compliance.

Through future deployment of “Prexifort-OCR e-Document Plus,” NTT DATA will contribute to the streamlining of document management of clients in the public sector as well as in the financial, insurance, medical, manufacturing, and logistics sectors.


Due to the legal obligation to maintain national tax-related books and documents for, in principle, seven years, many Japanese companies are experiencing problems in paper book and document management, such as securing storage spaces, delivery between offices, document search, and responses to losses. However, “Revision of Scanner Storage System for National Tax-related Documents” has been implemented in view of the “the Outline of the 2015 Tax Reform Proposals” and “the Outline of the 2016 Tax Reform Proposals”. Since the requirements have been significantly relaxed compared with the past, electronic document storage, such as time stamping, has been permitted under certain conditions. The new system is drawing the attention of many Japanese firms interested in shifting the document storage medium from paper to electronic.

Despite the relaxation of the requirements, document management planning, IT infrastructure construction, and filing with the tax authority must be properly conducted based on a correct understanding of the requirements of the Electronic Books Maintenance Act and the e-Document Act*4.

Taking advantage of knowledge on document management accumulated through over four decades of offering OCR services, NTT DATA will launch the sale of “Prexifort-OCR e-Document Plus.” This solution constitutes an IT infrastructure required by the Electronic Books Maintenance Act and e-Document Law in order to assist registration, storage, and utilization of national tax-related documents (contracts, bills, estimates, etc.).

Relevant national tax-related documents

  • Important documents (documents relating directly or indirectly to the flow of money and goods)

    Contracts, receipts, bills, delivery statements, checks, deposit certificates, due bills, promissory notes, security delivery account statements, export certificates, bond applications, contract applications (excluding formalized applications), bankbooks, invoices, etc.

  • Ordinary documents (other than “important documents,” account books, and closing financial statements)

    Order forms, estimates, inspection documents, cargo receipts, bank transfer request forms, contract applications (formalized applications), etc.


  1. 1Scanning and OCR feature

    The target form is scanned and read by OCR, and acquired text information is provided as a search keyword. Text information can also be acquired from a non-formalized form by the “keyword extraction feature” and “recognition by encircling feature.” Search keyword registration for electronic document production is streamlined.

  2. 2Time stamping feature

    A time stamp required by the Electronic Books Maintenance Act is automatically provided at the time of registration with an electronic document management server.

  3. 3Multi-condition search feature

    The search target document can be searched under multiple conditions (AND and OR) using a search keyword registered in advance. Efficient use of documents is enabled not only for responses to tax investigations, but also during ordinary operation.

  4. 4Security feature

    Restriction of user access on a folder and form basis and automatic acquisition of operation logs (viewing, search, and deletion) are possible. Assistance is offered for appropriate data storage.

  5. 5Operation and management feature

    Setting of a preservation period (e.g., legally required preservation period of seven years) is possible. By automatically deleting expired document files, the increase in costs for storing unnecessary documents and a decrease in search efficiency can be avoided.

Benefits of Introduction

  1. 1Reduction of preservation cost

    Costs for, e.g., document arrangement and management, storeroom spaces, storehouse renting, and delivery can be reduced by the introduction of electronic documents.

  2. 2Streamlining of document search

    High search efficiency enables streamlining of document use in the cases of internal and accountant auditing, inspection of past estimates and contracts, preparation of documents for various procedures, and retrieval of documents from the storehouse.

  3. 3Promotion of compliance

    The user control and log acquisition features allow for appropriate document management with ensured security.

Future Activities

Through the future deployment of “Prexifort-OCR e-Document Plus,”NTT DATA will contribute to the streamlining of document management of clients in the public sector as well as in the financial, insurance, medical, manufacturing, and logistics sectors.

  • *3“Time stamping” is a technology for proving the existence of a stamped electronic document by providing the document with a “stamp” containing information on the exact time generated by a reliable third-party organization Time-Stamping Authority (TSA).
