English to Japanese localization challenges
English has no built-in honorific system
Translating English dialogue into Japanese requires deciding speech register — formal, polite, casual — for each character based on context, not a direct equivalent.
English sentence structure differs fundamentally from Japanese
Subject-object-verb order and the agglutinative structure of Japanese require full sentence reorganization, not word substitution.
Character names need consistent katakana or adaptation
English character names transliterated inconsistently into katakana confuse Japanese readers.

English to Japanese translation FAQ
How does Novo decide which speech register to use in Japanese?
Novo infers social relationships from character interactions in the source text and assigns polite, casual, or formal speech to each character. Bilingual review lets you check specific dialogue scenes.
How are English character names converted to Japanese?
Names are converted to katakana based on standard phonetic conventions. You can supply preferred katakana forms in a glossary to override defaults.
Is this useful for English web fiction authors?
Yes. Authors with an existing English readership can produce a Japanese draft to test the market or engage Japanese fan communities.
