We got to like Japanese Green Tea. Because we first had it in a
restaurant, our Japanese friends found us "sushi bar style" green tea.

The same company, Yamamotoyama, besides "Konacha" which is the above,
sells also "Sencha", translated as simply Green Tea, "Kokya Sencha",
translated as "Premium Green Tea", and Saikokya Sencha, translated as
"Special Occasion Green Tea."

I would like to know what makes sushi bar style green tea different from
plain green tea, and would also appreciate any information about the
others.

Thanks.
