Proper noun
よこはま
「横浜から大阪までずうっと乗せてくれて、本当に有難うございます。」「どういたしまして！」
"Thank you so much for giving me a lift from Yokohama all the way to Osaka." "Don’t mention it!"
It's the side of the beach! Well, wait, what is it? This will make better sense when you look at the reading for the word, since it's a place: Yokohama.
The reading is 横 and 浜 put together into one nice word, よこはま.
