Spring is normally the best time to buy tea from Japan as it's when they get the first harvests of the year, but the Japan post has actually stopped accepting all shipments to America.https://www.amazon.com/Organic-Japanese-Sencha-Saemidori-Cultivar/dp/B07T9GB531
I've bought sencha from Amazon a few times, I've always felt that it's been old and stored improperly, and lacking in quality.
Just ordered this though, $25 for 100g is expensive for sencha but the other choice is $33 shipping from Japanese websites.
Only people I've found on Amazon that I could piece together that I'm getting 2020 harvested tea, and seem to care about quality.
Hopefully it's decent.
