This kana represents the mora nasal sound, which can be pronounced as [n], [m], or [ŋ] depending on the following sound. It never starts a word in Japanese and is often used at the end of words or between vowels. In romanization, it is written as 'n' and may be followed by an apostrophe before vowels or 'y' to clarify pronunciation. For example: 『あんしん』 (anshin, 'relief') shows it between vowels, and 『にほん』 (nihon, 'Japan') shows it at the end.
