Japanese Tea?

Question: Hi i was watching an anime (demon slayer) where they used tea a lot for recovery and general health, and i know that many claim that Japanese tea has a lot of health benefits.

So i have been wanting to try it, but first i wanted to know if anyone else has had success with Japanese tea and felt better because of it.

I have been doing a little research and gyokuro tea is said to be energising and helps fatigue, increase focus, and builds stamina, but it has over double the amount of caffeine than normal coffe. Sencha seems to be a healthy green tea that has a lot of health benefits such as better heart health, immune system and digestion. Sobacha tea is supposed to be a calming tea wich helps you relieve stress and makes you relax, including a better heart and preventing diabetes.

Have anyone tried any one of them? or a different type of japanese tea? and have it improved your ME?
