Why Japanese to English Translation Is Tricky
Before diving into the tools, it’s important to understand why Japanese to English translation poses unique challenges:
✅ Grammar Differences – Japanese is SOV (Subject-Object-Verb), while English is SVO
✅ No Direct Pronouns – Japanese often omits subjects, leading to ambiguity
✅ Kanji Complexity – Multiple readings for the same character
✅ Cultural Nuances – Honorifics (keigo) and politeness levels
This means not all translators handle Japanese to English equally well.
