The world of herbal tea is so vast beyond what you can get at your local supermarket. I've tried quite a few herbal teas in my life, but I can't even pretend that I have scratched the surface. I'm always on the look out for new flavors to enjoy and this got me to thinking. Are there any herbal teas that you think would be particularly beloved by someone who loves Japanese greens far above and beyond all else? Any that share similarities in any respect?
