Underwater Roller Coaster in Cosmo Land in Japan.
Looks really challenging and interesting.
The picture is even attracting people even more... but when I saw the real experience in Youtube, I take my word back.
It's not scary and it's too short.

Well, it's an amazing construction indeed though  :))

Japan condition after earthquake and tsunami is getting worse.
Plus, the nuclear and snow issues make this country suffers more.

Let's pray for Japan!
