夜景って英語でなんて言うの？

A 'vista' is a pleasing view or panorama and a moonlit vista may include looking from the cliffs over the ocean at night or viewing a city at night from a nearby hill. A 'night view' would be any view at night, although it may not necessarily be 'beautiful.' You may specify that it is beautiful if that is the case.

example "the city looks beautiful at night, it makes a beautiful nighttime landscape" or "the landscape is beautiful in the moonlight" or "what a lovely moonlit landscape".

Beautiful night views typically in American culture tend to be "romantic". You could also say the "stars were beautiful" There is no specific word in the English language for this exact thing. You need to describe what is beautiful, for example, stars, or city lights. You could say the "city lights at night are extravagant". Another descriptive term could be, " The view at night is beautiful because of the stars".

There is no direct english equivelant of "Yakei..." (Some words simply do not translate!) So in this case we might try to use moonlight, as the focus and express how pretty it can be to look out at night;-D Sometimes the moon is so full & bright, that we get a wonderful moon light view...

We do not have a direct translation for this. The closest would be "nightscape" which is a scene viewed at night, especially as represented in art. Words like sunset or sundown are specific to when the sun goes down. Twilight is the in-between time between sunset and darkness. The "sky at night" is more of a reference to stargazing so I would just use the words the "this is a fantastic view at night"

The view this evening is beautiful= The surrounding area is very pretty at night. You can replace the adjective "beautiful" with any synonyms such as "pretty", "gorgeous", or "lovely". The nighttime view is gorgeous= This is pretty much the same thing as saying "The view this evening is beautiful" only it is another way of saying it. The meaning is the same and you can also replace the adjective "gorgeous" with any synonym. The atmosphere this evening is so romantic= Your surroundings are extremely pleasing to the eye and is a good setting for couples/going on dates. You can also say this with out it being associated with love related things depending on the context. It can also just mean the view that evening is very pretty.
