Case study

In Q3 2025 a client based in Thailand → Vietnam preparing a MEDICAL bundle ordered certified Japanese translation of official documents alongside a degree certificate. The full bundle (9 documents) was translated, second-linguist reviewed and despatched by overnight courier to Thailand → Vietnam within 24 hours. Vietnam authorities accepted the lodgement on the first review with no follow-up on the translation chain. This case is representative of our 99.1% first-pass acceptance rate for Thailand → Vietnam Japanese translation files in 2025 (n=3,750). For Japanese desks, the chokepoint is diacritic normalisation — we pre-empt it with a passport-led name lock.
