What each kanji means
To govern, to heal — order restored. Osamu (治) and Haruji recall the Meiji (明治) era of modernization; a name for one who sets things right.
Increasingly, all the more — the 弥 of Yayoi (弥生), Japan's ancient spring era. Yayoi and Mio (弥央) suggest continuous deepening, like spring advancing.
A beautiful black jewel — a rare, poetic character. Its jewel meaning and unusualness make names like Kurumi (玖瑠実) feel like hidden treasure.
