It's not the same, but I still remember the first time I was served genmai cha (roasted rice tea) at a sushi restaurant. I loved it and inquired, the server was kind enough to show me the actual tea bag — it was Yamamotoyama. Available lots of places in the US, but I used to buy it at a Japanese grocery store.

I consume copious amounts of cold mugicha. It's amazingly refreshing and very cheap.

Also called boricha on Korean. Can find in local H Mart.

I have not tried the Japanese roasted barley variety but houjicha, roasted green tea, is excellent and can find in Japantown.

why not both?

so cool! big fan of barley tea growing up with it

I wonder if you can get this outside Japan. I'd love to try some.
