"Factory night view" is understandable, but it’s not the most natural phrase in everyday
English. A more natural way to say it would be:
* "Factory nightscape" (a bit formal, often used in photography or tourism)
* "Factory skyline at night" (if referring to a wide view with multiple factories)
* "Factory lights at night" (more conversational)
For your sentence in a casual conversation, you could say:
➡ "I just went to see a factory nightscape. The lights were really beautiful! In Japan, some people enjoy checking out factory night views."
Or, if you want a more natural flow:
➡ "I just went to see a factory at night—the lights were beautiful! In Japan, some people love watching factory nightscapes."
