We are a ‘tea to cup’ tea producer located in lower Hiroshima. In the tiny farming town of Sera we grow a fertilizer & pesticide-free tea at an elevation of 400 meters.

The rice and vegetables grown in the Sera plains are quite delicious with the seasons quite harsh. Tea here is no exception as it once was prized as the best in the Hiroshima region for its magnificent aroma.

Since 2016, we have cultivated tea with plants native to Sera and in 2019, through happenstance found a 70 year old tea factory nearby that now serves as our main production facility.

Our tea production with our leaves extends beyond sencha green tea, as we produce Hamacha, a sea breeze tea naturally dried by the water, a fully fermented Japanese black tea, partially fermented oolong tea, and slightly fermented white tea. Our production method incorporate elements of Taiwanese and Chinese tea.

Taking into consideration the maturity of the leaves, we determine whether to process our tea by hand or machine and further we cultivate both hand picked and machine picked tea!

Our passion for creating tea culture
Tea Factory Gen Naturally Grown and Produced Unique Teas We are a small sustainable tea farm in Sera, a small agricultural town in Hiroshima Prefecture, striving to produce unique teas that create harmony between mankind and nature.

Like a group of trees peacefully growing in a forest, our tea plants are grown in as natural an environment as possible without pesticides or fertilizers of any kind.

Since we avoid the use of fertilizers, our harvest yield is less than half that of traditionally farmed teas and since we avoid the use of herbicides to control wild grasses that grow amongst our tea plants, a tremendous effort is required to carefully remove all the weeds.

No matter how much effort is needed to control the weeds or how low the harvest is on our land for each year, we persist in maintaining our unique, natural method of tea production.

Our farming & production method was established because creating unique tea is our top priority and for that, not using fertilizers is indispensable.

Furthermore, not using pesticides is also key for everyone to be able to place trust in our tea farm and to enjoy tea that doesn’t risk their health.

In addition, out of respect for nature, we feel it is important to maintain a sustainable way of tea production that in turn produces our unique teas.

Our tea production principles are as follows:
1. Looks aren’t everything
2. Umami isn’t everything
3. Tea color isn’t everything
4. Despite the risks, adhering to creating tea our way
5. Producing a tea that when drinking it will make you elated
6. Making a tea that leaves a crisp and refreshing aftertaste like a natural breeze
7. Cultivating teas with an open mind
