Japan without a doubt. I would go there in early October to make sure I caught the annual tea festival in Uji and got to visit the Tsuen teashop and have a nice cup of Japanese green there.
Other than that I would remain in the area around Kyoto and south and make sure I got to see as much of the historic Japan as possible, and of course visit the Buddhist temples.
I'm gonna have to scrape the money together soon
Been thinking about going there for many years, but if I'm going, I'll be there a while.
No tea so far today, it's 9 in the morning, that's a bit early for tea for me. University starting again today
Gonna go for some Gyokuro Yume no ukihashi from Uji when I get home, then I'll browse Japan travel info as I usually do when I drink good green tea, the tea brings me halfway there
