While much of the world celebrates Black Friday, at Kyosun we celebrate Green Friday – in the colour of matcha and of the Japanese fields it comes from. This year it comes with a simple message for everyone who buys from us: thank you. And because a thank-you should be more than words, from today until 30 November (or while stocks last) you get 10% off everything in our B2B shop.

Thank you for working with us
Behind every order in our shop is a café, a pastry kitchen, a food producer, a distributor or a brand building its own private label. Some of you have been with us for years, some joined only this season. Thank you for your trust, your questions and your feedback – and for your patience on the days when Japanese harvests and shipping times did not run like clockwork. Green Friday is our way of giving a little of it back.
Your orders also make our testing possible
Part of every order goes back into quality control. We have been testing our grades in an accredited laboratory since 2014, and every report is public at quality.kyosun.com. This autumn we went one step further: we bought 21 matcha brands on the Czech market as ordinary customers and had them tested together with two of our own teas in the same accredited laboratory, ALS Czech Republic.
What the test of 23 matcha teas showed
- 5 of the 21 market products declare China or South Korea, or contradict themselves about origin – all are sold as matcha.
- Two teas with the organic logo contained insecticides at 61 to 130 times the level for organic products.
- 19 of the 23 samples had no detectable pesticide residues at all.
- Lead differed 14-fold, chromium 25-fold and the price per gram 32-fold.
- Kyosun A+++ came first overall and Kyosun A+ third – the weights of the ranking are ours.
Full disclosure: we commissioned and paid for the test, and our two teas were bought, sent and measured exactly like every other sample. The market brands stay anonymous. The whole story is in our article 23 Matcha Teas, One Laboratory and in a video on YouTube. Thank you to all of you who asked us about origin and lab reports this year – questions like these are exactly why we did it.
Five ideas to make the most of the 10%
- Plan your stock for the first months of 2027. Winter and spring menus are often decided before Christmas – now is a good moment to secure your matcha for them.
- Try a grade you have not used yet. Our 50 g samples are included in the discount – the easiest way to compare grades side by side.
- Combine orders into one shipment. Fewer, larger deliveries mean lower shipping cost per kilogram.
- Start or grow your private label. Packaging without our label is part of the range, so the code applies to it too.
- Ask for the lab report of the batch you buy. One report, one batch – that is how we work, and how it should be.
Until 30 November – and not a day longer
The code GREENFRIDAY works until 30 November 2026 or while stocks last. We will not extend the offer and we will not repeat it this year. If you have questions about stock, grades or larger volumes, write to sales@kyosun.com – we are happy to help.
Thank you for this year together, and see you in the cup.
