For Customers’ Satisfaction

One of the most prestigious awards "Minister of Agriculture, Forestry and Fisheries Award" was conferred.

We are with a natural environment

Japan is a country surrounded by the sea on all sides and full of natural beauty, and forests cover about 66% of Japan's land area. A variety of agriculture has flourished in this natural environment.


Gratitude is at the origin


As a manufacturer and wholesaler of Japanese tea, the first thing I want to say about receiving such a prestigious award is that we are grateful to our partner farmers who continue to produce wonderful raw ingredients. We are simply making a little arrangement of the originally delicious itself. The shape and flavor of the tea leaves are significantly affected by the growing process, and we are really happy to be able to present the maximum of the tea's characteristics in a greatly.



Your smile is the best prize


However, we always think that the award or difficulties in awarding a prize do not have anything to do with whether Japanese tea is tasty to you. Everyone has their own taste preferences, and we cannot say that tea is delicious because it is an award-winning tea. No matter what award we receive, it is always the customer's satisfaction that is the best prize of all.

Smooth like silk on the palate. The scent of the roasted rice and matcha intemingling like the finest fragrance.

Excellent sencha. I did not taste any bitterness at all.

My favourite

The taste is balanced And not too bitter

Thank you so much for sharing your taste review. :)

Balanced of sweetness and bitterness

This one is the perfect balance of sweetness and bitterness for me. I am not fan of bitterness of tea but this combination of sweetness and little bitt of bitterness makes me feel energetic. I smell and taste the freshness with every sip in the morning. it contains 20 grams I feel the quantity is not too much. So now I wanna try their other matcha to compare.

Hello, Amber.
Thanks for leaving a thoughtful review about our matcha.

My Favorite Matcha

I have used this Koiai matcha for 3 years now since my Japanese friend recommend. I love it! It is the best I have tasted. It's fresh and nutty as well. I used to drink coffee every morning but now I make my own Matcha lattes at home. It is very dense because it is high quality ceremonial matcha so make sure you sift matcha for creamy and foaming.

Thank you for loving KOIAI Matcha. We will share this great review with our farmers. Thank you again.

Lacking customer service

I reached out twice to Osada Tea regarding my tea order, once before I bought the tea and once after regarding the discount that I did not apply and the first time a question about radiation. I never heard from anybody on either of my questions. Also the tea that I ordered tastes really bad and I don’t know why but I just can’t drink it so I was a bit of a waste of money for me and I will not be re-ordering
