Shibuya
proper noun
The bitter valley is a place known as Shibuya. This is a very famous area in Tokyo. Very busy too.
The reading for 渋 comes from 渋い. The reading for 谷 is one that shows up mostly in place names and surnames, so maybe you haven't seen it yet. To remember it, just imagine someone asking you if Shibuya is cool. Your answer of course is "yah" (や).
私はよく渋谷駅で外国人を見ます。
