The actual name is "karesansui" meaning dry landscape. It is not technically called a Zen Garden but is often referred to as that. They are called Japanese Rock Gardens.
The picture depicts a karesansui garden, or "Japanese rock garden". To depict the whole philosophy, religious thought and concept known as "zen" with a picture of a karesansui is ridiculous. The creator should've at least written a clue like with the other pictures.
Yay, I went to Japan in April! Only missed 'Macaque', because I couldn't spell it! Thanks for accepting 'Sakura' for Cherry Blossom, and 'Shinkansen' for Bullet Train.
I got it because the exact same picture was used on the quiz Pointless today! What are the odds (especially since I didn't really watch the show this time and only saw a few minutes of it near the end)
You should accept Rock Garden for Zen. That is the correct term. They are often called Zen Gardens but for the simplistic form, they ARE called Rock Gardens.
I've lived in Japan for years and I have never heard about the monkeys in Nagano being called "macaques" (which to my understanding, just comes from a word for monkey in Portuguese/French), and I definitely never heard of the rock gardens being referenced to as Zen gardens.
