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. Also, depending on whether the word to be converted is "name" or not, the conversion rules may differ. 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
