The words might be right, but they won’t work very well.
It would be wise to only bring friends of the same sex. Romantic gestures such as hugging and kissing are considered best kept private.
Common locations for these kinds of dates are movies, parks and cafes, but there are some other appropriate options.
Among Japanese young people (high school and college-aged students), two people start dating by making a “love confession.” That’s where the phrases “I like you” and “I love you” below might come into play.
In any case, during the early stages of getting to know someone, the compliments should be light and sweet. Let’s say you want to tell your companion that they look beautiful. But what if you’re a beginning Japanese learner and even that seems too ambitious?
Maybe you want to ask them if they happen to be a model? Here’s a good one to try:すみません、英語が分かりますか？ (すみません、えいごが わかりますか？) Excuse me. If you’re not too strong in Japanese and you’re hoping that your crush can meet you halfway, then this is a viable option for getting your first conversation started.
