Correspondences Between Dialects
There are regular correspondences between Tokyo-type and Keihan-type accents. The downstep on high-tone words in conservative Keihan accents generally occurs one syllable earlier than in the older Tokyo-type of accent. For example, kokoro 'heart' is /kokoꜜro/ in Tokyo but /koꜜkoro/ in Osaka; kotoba 'word' is /kotobaꜜ/ in Tokyo but /kotoꜜba/ in Osaka; kawa 'river' is /kawaꜜ/ in Tokyo but /kaꜜwa/ in Osaka. If a word is unaccented and high-tone in Keihan dialects, it is also unaccented in Tokyo-type dialects. If a two-mora word has a low tone in Keihan dialects, it has a downstep on the first mora in Tokyo-type dialects.
In Tokyo, whereas most non-compound native nouns have no accent, most verbs (including adjectives) do. Moreover, the accent is always on the penultimate mora, that is, the last mora of the verb stem, as in /shiroꜜi/ 'be white' and /okiꜜru/ 'get up'. In Kansai, however, verbs have high- and low-tone paradigms as nouns do. High-tone verbs are either unaccented or are accented on the penultimate mora, as in Tokyo. Low-tone verbs are either unaccented or accented on the final syllable, triggering a low tone on unaccented suffixes. In Kyoto, verbal tone varies irregularly with inflection, a situation not found in more conservative dialects, even more conservative Kansai-type dialects such as that of Kōchi in Shikoku.
