Case study
Market entry built on proof, incentives, and structured strategy.
Overview
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.

Challenge / Transformation / Impact
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.
What we made
Japan market entry / growth strategy deck (segmentation, SWOT, channel approach); Persona set and targeting framework for key Japanese user profiles; JMEC testimonial video package:; - Main testimonial edit (3–4 minutes); - Short cutdowns (15–30 seconds); User survey framework for feedback collection and iteration; Premium voucher creative assets (30-day and 90-day trial gates); Localized website and payment experience direction (Japan trust signals); Japanese company kit content structure (product intro, features, how-to, Q&A); Japanese blog localization direction (common JP-user grammar patterns); Asset library governance for ongoing YouTube and SNS content rollout
