Case Study: Mercari achieves translation consistency and faster, measurable localization with Phrase Localization Platform

Maintaining Translation Consistency with Memsource

Mercari, operator of Japan’s largest marketplace app and the Merpay payment service, faced growing translation challenges as its Tokyo office became more international. What began as a small in-house translation team scaled rapidly, creating inconsistent translations across related documents and repeated work when updates were retranslated from scratch despite existing translations and glossaries.

To solve this, Mercari implemented Memsource in 2019 and built a translation memory and term base that immediately reduced duplicate work and ensured consistent terminology across files. Memsource’s TM auto-fills unchanged segments, surfaces glossary suggestions per segment, and — via a Google Drive connector — provides accurate character counts and match-rate breakdowns, enabling faster turnaround, better workload estimates, and improved translation quality.
