Similarly, the names "Tōkyō" ("To-u-kyo-u", ), "Ōsaka" ("O-o-sa-ka", ), and "Nagasaki" ("Na-ga-sa-ki", ) all have four morae, even though, on this analysis, they can be said to have two, three and four syllables, respectively. The number of morae in a word is not always equal to the number of graphemes when written in kana; for example, even though it has four morae, the Japanese name for "Tōkyō" () is written with five graphemes, because one of these graphemes () represents a "yōon", a feature of the Japanese writing system that indicates that the preceding consonant is palatalized.
