I like Japanese names. Though I so feel it weird if someone who does not look obviously Japanese has a Japanese name. I suppose it may be because their culture has not been so accesable in our society for as long as other cultures like the ones you listed.
In Japan people thought that one of my parents must have been Japanese because they saw my name,
Naomi, as being Japanese. I actually like the fact that I have a Japanese name when I need it - and an English one too.
Of your favourites I like:
Aiko SoraMaiSakura - love the cherry blossom.
Akiko - with the meaning of sparkling/shining one.
What do you think of:
Haruna
Megumi - like because could give an easy English nn "
Meg".
KeikoEmiMaki
Eri
Eriko
MikiKana
Mutsumi
Kazue
Nahomi
Fumie
Sadako - 1000 paper cranes
MinaChiharu
Midori is unusable to me these days as it's an alcoholic drink.
You can make up names using different sounds, just like the names have different meanings depending on the kanji used. I like Fuyumi with kanji to mean "beautiful winter".
Did you want any kind of fn/mn? or a Japanese one?
