Romaji converter

cutlet

Cutlet is a tool to convert Japanese to romaji.

Features:

• support for Modified Hepburn, Kunreisiki, Nihonsiki systems
• custom overrides for individual mappings
• custom overrides for specific words
• built in exceptions list (Tokyo, Osaka, etc.)
• uses foreign spelling when available in UniDic
• proper nouns are capitalized

Things not supported:

• traditional Hepburn n-to-m: Shimbashi
• macrons or circumflexes: Tōkyō, Tôkyô
• passport Hepburn: Satoh (but you can use an exception)
• hyphenating words
• Traditional Hepburn in general is not supported

Internally, cutlet uses fugashi, so you can use the same dictionary you use for normal tokenization.

Installation

Cutlet can be installed through pip as usual.

pip install cutlet

Note that if you don't have a MeCab dictionary installed you'll also have to install one. If you're just getting started unidic-lite is probably fine.

pip install unidic-lite
