Overview

The brief

Grammarly’s Japan growth required more than translation. It required proof, incentives, and a market-entry operating system that turns low awareness into trust and trial. We supported the Japan market strategy and executed a testimonial content program (JMEC) plus localized acquisition assets, so Grammarly could build credibility and adoption in a low English-proficiency market.

The work

01 / Challenge

Japan's low English proficiency and high price sensitivity create a structural barrier for an AI writing assistant: users need evidence that the product fits real Japanese workflows before they commit. Grammarly needed a market-entry system built around proof and low-friction trial.

02 / Transformation

YF developed the Japan market business plan and segmentation framework, then designed and produced a JMEC testimonial package to provide credible, local proof. Voucher mechanics and trial infrastructure were built to lower the barrier to first use across key segments.

03 / Impact

Grammarly gained a structured Japan market-entry foundation that combines strategic planning with tangible proof assets. The testimonial library and trial mechanics created real conversion points for a market that demands evidence before adoption.
