The name
Keihan
, which is also used for the Kyoto-Osaka region, is derived from the words
Kyoto
and
Osaka
in Japanese, and is a
clipped compound
of the names, with the reading of the characters changed:
Kyōto
(京都) and
Ōsaka
(大阪) are combined to
Keihan
(京阪), replacing the
go-on
reading
kyō
(京) and
kun‘yomi
saka
(阪) with the
kan-on
readings
kei
(京) and
han
(阪)。 This is commonly done in names for regions or train lines, with (as here) the kan-on readings (most common readings in
kanji
compounds) being used for the compounds, while the place names use other readings。 The larger region, including
Kobe
(神戸,
Kōbe
), is similarly called
Keihanshin
(京阪神,
Keihanshin
), the go-on reading
shin
(神) replacing the kun’yomi
kō
(神), and the corresponding Kyoto-Kobe line is the
Keishin
(京神,
Keishin
) line。
