Sokuon

As a rule, Sokuon are repeated with the immediately following consonant letter.
As an exception, if the immediately following is "ch", it is treated as "tch".

Hatsuon

As a rule, Hatsuon "ん" is represented by "n".
As an exception, "m" is used only before "b, p, m".

Chōon

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

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
