"All-nighter/sleepless night" in all languages

[Avril_avril]

Hi, I'ld like to translate "all-nighter" or "sleepless night" in a lot of languages.
The meaning is the cultural event, when people are strolling in the streets to see exibitions, concerts...
I allready have some translations, but I need more!
IMPORTANT: I also need to know how to pronounce it, even approximately.

I have:
ليلة بيضاء (Arabic)
לילה לבן (Hebrew)
schlaflose Nacht (German)
notte bianca (Italian)
BIAŁA NOC (Polish)
nuit blanche (French)
noche en blanco (Spanish)
slaploze nacht (Dutch)
uykusuz gece (Turkish)
noaptea alba (Romanian)
nata e bardhe (Albanian)
Baltā Nakts (Latvian)
søvnløs nat (Swede)
Taiteiden yö (Finnish)
bezesná noc (Czech)
Lejl Imdawwal (Maltese)
白夜 (Chinese)
眠れない夜 (Japanese)

I need 15 more!

Thank you!!

眠れない夜 (nemurenai yoru) means "a night when one can not sleep", thus can not be used for this kind of event.

Thank you! So, what can I say in Japanese?

noaptea alba (Romanian)

Little correction for Romanian: noapte albă [white night]. Noaptea is with the definite article – 'the night'.

One more, in Hungarian:

álmatlan éjszaka [sleepless night]
