Versions of Report

To help stakeholders effectively and efficiently understand our value creation in business, we prepared different versions of the 2018 Report and focused on reporting in line with Material Issues.


Brochure, PDF Edition In consideration of the information required under international disclosure guidelines, the brochure and PDF edition are prepared for stakeholders, such as investors and NGOs, who need a broader range of non-financial information about INPEX.


Web Edition Designed to provide up-to-date data, the web edition combines disclosure information that provides an overall picture of CSR with content from past Sustainability Reports and the latest CSR data.


This report contains not only historical and current facts about INPEX CORPORATION and its affiliates (INPEX), but also forward-looking statements based on forecasts, estimates and plans, etc. Because these forecasts, estimates and plans, etc., are based on information available at the time of reporting, they are subject to uncertainties. Actual future business results and events may differ from these forecasts, estimates and plans. We will accept no liability with regard to such situations. Readers should be aware of this when reading this report.
