Case Study: Kaho Musen achieves 100x faster insights (minutes vs weeks) with Tableau Software

Kaho Musen delivers insights in minutes instead of weeks with Tableau and cloud databases

Kaho Musen, operator of the Home Center GooDay chain with 63 stores in northern Kyushu, faced a challenge turning large volumes of POS and supplier data into actionable insight. Using Excel was impractical and custom coding could take up to three weeks, so the company needed a faster, easier way for teams to test hypotheses, spot issues, and communicate with branch managers.

The company deployed Tableau on AWS, with analysts authoring visualizations in Tableau Desktop and sharing them via Tableau Server to query roughly 160 GB of data. Systems, Project Management and Sales buyers now create reports in minutes instead of weeks—Mr. Yanase estimates analysis time is about 1/100th of what it was—leading to smoother store-level communication, a new data-driven management policy, and plans to train more staff in analytics.
