Umios (formerly Maruha Nichiro)

Sales-plan forecasting with the Chronos-2 time-series model

Umios, formerly Maruha Nichiro, reported a 95% match between Chronos-2 forecasts and its sales plans before going into production

WorkingCompany's own claim

Problem

Sales planning for the company's business-use products took many staff hours each year, and excess inventory also needed manual handling. The company set a target of cutting 4,200 hours a year.

Approach

The company used Amazon's Chronos-2 time-series model through an API on AWS. A workflow pulls shipment history and inventory data, and forecasts go to a BI tool where planners review them before they enter the planning system. The model was received in December 2025, tested from February 2026 and put into production in June 2026. Seasonal items showed larger errors, so the company set a safety-stock approach for them.

Results

95%match rate between forecasts and plans in verification, against an agreed production threshold of 80%, as stated by the company; the 4,200-hour annual saving is a target, not a resultCompany's own claim[1]

Takeaway

The company agreed an accuracy threshold before the test and kept planners as the final decision makers. The 4,200-hour saving was still a target.
