Borrowed straight from Japanese kanji (
志乃 / しの, 'Shino'), pronounced with Mandarin readings rather than sound-transliterated. The same convention applies to many Japanese names:
山口 (Shānkǒu / Yamaguchi),
美咲 (Měixiào / Misaki). Shino is a classical-feeling Japanese girl's name with literary associations — Genji-era and Edo-period heroines often bear it.
