Sokuon

As a rule, Sokuon are repeated with the immediately following consonant letter.
As an exception, use "tch" when the immediately following is "ch".

Example

きっと → kitto
こっち → kocchi → kotchi

Hatsuon

As a rule, use "n" for Hatsuon "ん".
As an exception, use "m" when the immediately following is "b, p, m".

Example

はんこ → hanko
さんばし → sanbashi → sambashi
あんぱん → anpan → ampan
あんまん → anman → amman

Chōon

Convert "uu" to "u".
Convert "oo" and "ou" to "o".

Example

くうき → kuuki → kuki
おおきい → ookii → okii
ほうき → houki → hoki

Supplement

There are various types (variants) in the Hepburn romanization. However, since it is difficult to support all types systematically, the conversion rule 'Convert "oo" and "ou" to "o".' is applied to Chōon. Therefore, it is a specification that "いのうえ" is converted to "inoe".

Example

いのうえ → inoue → inoe
おうえん → ouen → oen
かのう → kanou → kano
のうか → nouka → noka
