    What Is the Lean Six Sigma Green Belt Certification?Your Route to Data-Driven Improvement

    The Lean Six Sigma Green Belt (LSSGB) is an intermediate process-improvement credential that validates your ability to lead and support data-driven improvement projects using the DMAIC method.

The programme is mapped to the IASSC Green Belt Body of Knowledge and covers all five phases of DMAIC: Define, Measure, Analyse, Improve and Control. You build core statistical skills such as hypothesis testing, basic regression and process capability, alongside Lean tools like 5S, value stream mapping, Kanban and Poka-Yoke. There are no prerequisites, so practitioners from any sector can begin. Delivered in live virtual and corporate formats across 32 hours of instruction, the training suits quality engineers, operations specialists and improvement leads in Tokyo. You move from study to certified with structured practice, mock questions and trainer guidance every step of the way.
