How you store the Japanese green tea is very crucial. Since Japanese green tea are very delicate tea products, the longevity of the tea will differ depending on how you store the teas. These are the five factors that you should avoid when storing Japanese green tea.
I notice the scent will go down depending on how its stored. To enjoy the best teas, please try to avoid the above and keep the teas in good condition.
Also tea cans/canisters will also be great for storing teas. I usually put the teas in tea cans and store it in refrigerator. As for our tea products, since there are in really good sealed tea packages, by keeping it sealed and putting it in refrigerator will do the work. If there are any other questions, please feel free to ask anytime:)
