I need help coming up with a Japanese name for my son that will be born in two months. He is half Japanese, but his mom's family has been in America for four generations and aren't native speakers. We named his older brother Kaito (海斗) which we love but are having trouble coming up with a name for this one. I really like the meaning of the name Ozora (大空) -- "big sky" as I understand it (My family is from Montana, it's the state motto) but honestly I don't really like the way it sounds. Are there other readings of that Kanji? Or other names/Kanji that have a similar meaning? Thanks!
