What is the name of the symbol in the top left corner?

It's the Japanese character for Heaven. It's pronounced as "Ten" sometimes, depending on how it's used. This is a logo that Tenzen uses sometimes, probably because the first syllable of his name sounds like Heaven in Japanese, Tenzen.

He also uses it in some of his earlier work, such as here.
