Chaseki was established by Tom and his wife JJ in 2018 in Chiang Mai with a clear mission – to find and offer the most delicious teas and to educate everyone willing to learn more about the amazing product tea.

We have created a place to find the best teas Japan has to offer easily. Our suppliers have been refining the highest quality leaves from all Japan and have been proven by the many awards won over the years.
During his tea journey, Tom began to realize one key issue. He learned that it is quite challenging to find premium quality Matcha and Japanese teas outside of Japan and this is due to the fact that 97% of tea produced in Japan, stays in Japan.

So we have decided to source our products directly from local tea farmers and small tea businesses from all famous tea regions in Japan.
There are many reasons why it is so challenging to obtain variety and quality from the Japanese tea market for buyers outside of Japan.
The key issues are language barriers and aging. The average age of farmers is over 60, and the younger generations rather chose a corporate job in the city over the hard work of farming.

Less than three decades ago, there were over 200,000 tea farms all over Japan: in 2015, there were only 20,144 left.

As in many places, mineral water, soft drinks, and of course, coffee are getting more and more popular and begin to replace tea in Japan slowly.
By sourcing our products from traditional and innovative young tea farmer, we help to keep and to protect the Japanese tea culture.

Tea is really good for you! It is absolutely delicious, an accumulation of all the great things in life. Tea is healthy, connects people from all parts of the world, and it’s natural.

Forget everything you know about tea so far, and get ready to join our journey.

Discover award-winning Matchas and teas from all regions of Japan, only at Chaseki teahouse.

We are looking forward to seeing you soon.

 I absolutely love tea and especially Matcha (Japanese green tea). I lived in Japan for 1.5 years and had many formal tea experiences there. I can confidently say I've finally discovered the best tea room I've ever experienced outside of Japan!
In fact, the tea infusions are of such high quality, includes unique blends, and the added experience of speaking directly with the owner who is passionate about tea that this is definitely on-a-par with what I've had in Japan. 
If anyone visits Chiang Mai in Thailand, make sure you pop in to Chaseki for some Matcha. A must for all tealovers
