	In Go-on and Kan-on, the Middle Chinese coda "-ng" yielded a nasalized vowel, which in combination with the preceding vowel has become a long vowel in modern Japanese. For example, "Tōkyō" , is "Dōngjīng" in Mandarin Chinese. Also, as Japanese cannot end words with consonants (except for moraic "n"), borrowings of Middle Chinese words ending in a stop had a paragoge added so that, for example, Middle Chinese "kwok" () was borrowed as "koku". The later, less common Tōsō-on borrowings, however, reflect the reduction of final stops in Lower Yangtze Mandarin varieties to a glottal stop, reflected by Japanese /Q/.
