Note that, the name 'Wakamatsu' (literally 'young pine') comes from 'Wakamatsu-no-mori' (literally 'young pine grove') which was in the vicinity of the approach to Umamiokawatamuki-jinja Shrine (the Gamo clan's family shrine near present day Murai, Hino-cho, Gamo-gun, Shiga Prefecture) and close to Matsuhide's birthplace, Hinode Castle (Nakano Castle), also the 'Matsu' of 'Matsuzaka' is also the kanji character for pine and is said to have the same roots.
なお、「若松」の名は、出身地の日野城（中野城）に近い馬見岡綿向神社（現在の滋賀県蒲生郡日野町(滋賀県)村井にある神社、蒲生氏の氏神）の参道周辺にあった「若松の杜」に由来し、同じく領土であった松坂の「松」という一文字もこの松に由来すると言われている。
