Harbor
Port
noun
The kanji and the word are exactly the same. That means they share meanings as well.
This is a single kanji with no okurigana, so it's using the kun'yomi reading. You don't know this reading yet, so here's a mnemonic to help you:
You go down to the harbor and speak the secret password me natto (みなと) to buy some fresh natto. Imagine the salty air hitting your face as you whisper, "me natto." Now eat that yummy natto by the water! Mmmm!

台風が来たら、港には近づかないで下さい。
Don't approach the port when a typhoon comes.
