What is “I miss you” in Japanese?

There are words that do not have exact equivalents between foreign languages. For example, "miss". How would you say "I miss you" in Japanese? I think there is no one specific Japanese word expressing "miss".

 miss: to feel regret about the absence or loss of somebody or something

 I miss you. : anata ni aitai. (I want to see you.)

 I miss my mom's food. : okaasan no ryori ga tabetai. (I want to eat my mom's food.)

Verbs change depending on the object of the sentence.

koishii is similar to "miss", but it is used only for song lyrics or poems, not used for everyday life.

 koishii: to feel attraction  for a person, place or thing that you are physically separated from.

Moreover, many non-Japanese often use "natsukashii", but its usage could be wrong sometimes, so please be careful. Natsukashii means that you have a feeling of "miss" when you remember the distant past.

 shogakko jidai ga natsukashii: I miss my elementary schoold days.

 mukashi no tomodachi ga natsukashii: I miss my old friends.
