Japanese Horseradish
Noun
わさび
やはり、すりたての山葵は美味しいね。
Of course, freshly shaven wasabi is delicious.
If you dig up hollyhocks in the mountains, and grind up their roots, you'll have wasabi! Don't eat too much, or you'll burn your tongue off.
This reading is an exception, but I'm sure (at least I hope) that you've heard the word wasabi before. It's the same in Japanese so just remember the meaning and you'll know the reading too!
