This community is managed by the Japanese Whisky International Council, a registered general incorporated association.

In collaboration with our dedicated whisky enthusiast members, we are committed to supporting the future growth of the Japanese whisky industry through initiatives such as the planting of Mizunara oak trees.

Every person who becomes a member of this community will directly and personally contribute to the growth and future of Japanese Whisky.

To support the following projects, a part of the annual membership fee we collect will be donated annually to these projects.
The names of each contributing member will be attached (if consented) to the projects when making the donation.

Ensuring the preservation of Mizunara oak trees for future generations is fundamental to protecting and enhancing the legacy and value of Japanese whisky for centuries ahead.

"The use of Mizunara Oak is a special characteristic of Japanese whisky, and I want to pass on whisky production which uses Mizunara Oak to the next generation."

Mizunara as a material for casks has attracted attention in the whisky industry from all around the world.
However, it takes about 100 to 300 years for a Mizunara Oak tree to grow, after which it is ready to be used as a cask barrel.
If all existing Mizunara trees are cut down and used now, it will no longer be possible to enjoy whisky aged in Mizunarama casks in the future.
It is our mission to contribute to creating an environment in which the world and future generations can drink and enjoy whisky aged in Mizunara casks by preserving and growing new Mizunara trees.

The details of support and donations will be published on this community page every year.
We support Seiichi Koshimizu's dream and invite you to join us in our efforts in creating a sustainable future and environment of whisky.
It is our hope that these projects become the identity of all members of this community and we pledge to do our part for the world of whisky.
