What clients say Hiyaku Inc does well
WISLR read 60 of the 79 client reviews on this agency's Shopify profile and looked for what merchants repeat. This is our reading of the patterns, not a quote from any review.
-
Cross-border store launches
A large share of reviews concern overseas-facing builds for Japanese brands: multilingual English and Chinese storefronts, guidance on customs, invoicing, shipping and payment setup for foreign buyers, and attention to translation nuance so brand messaging survives localization. Several merchants also consolidated domestic and cross-border operations into a single Shopify store.
-
Standing meeting cadence
Merchants repeatedly cite weekly or biweekly fixed meetings, visualized schedules and task sheets, and progress shared at each checkpoint. Launches landed on the planned date in many accounts, including several with compressed timelines or client-side delays absorbed by rearranging the plan.
-
App comparison proposals
Multiple reviews describe the team researching several candidate apps for a request, testing them, and presenting merits, drawbacks and downstream operational impact before recommending one. Choices were framed against budget and running costs rather than pushed as a single option.
-
First-timer onboarding
Merchants who arrived with no ecommerce knowledge describe explanations matched to their level, how-to videos for admin tasks, operational lectures near launch, and continued support after handover. Several also received help with Japanese IT subsidy applications alongside the build.
