Today, Japan Tokyo weather was rain. and cold.
I always drink a hot coffee and cold green tea at mornning.
I like cold japanese green tea, called "ryoku-cha"
and browntea, called "houzi-cha"

Most likly Japanese tea was no sweet. something like that
Bitterness.

but,
When I went to business trip foreign controy,
I did not want to japanese tea. I drink minellal water.

I consider the forgine climate influence.
