About Isshin

Isshin is run by me, Miuyki Oda. Isshin / 一心 means one heart. I would like you to not only pass by Isshin, but to feel like a special guest when you visit us. I took great care in selecting the best Japanese green teas – differing in origin, taste, ingredients and properties. Apart from many types of green tea, at Isshin you can also find other authentic Japanese products such as: handmade ceramics, unique Japanese items hand-sewn from kimonos, sweets and a selection of tea preparation tools.

Our teas are packed air-tight and stored in a temperature below 0°C to preserve the best taste and the unique properties of the tea that are only present in the freshest of dried tea leaves.

During unique workshops I will teach you how to brew your own cup of Japanese tea, how to whisk Matcha or how to prepare traditional Japanese Wagashi made from sweet bean paste and hand-shaped into small works of art. The workshops will deepen your knowledge of the Japanese tea and culture. A workshop can also be a great gift for someone that you wish to invite. During the workshops you will become familiar with different teas and gain first-hand knowledge from an authentic Japanese perspective.

With my passion to connect the beautiful cultures and the rich cultural heritage of both the Netherlands and Japan, since 2016 I combine tea and tourism and organise “tea tours” that can deepen your knowledge of art, history and the practice of Japanese tea. If you are interested in visiting Japan with Brilliant Tours, please send us a message.
