Exclusive to Japan, our terroir of Andosol (rich volcanic soils), microclimate, mountain water, and mountain elevation produce the rare saffron phenotype that we call Akaito Saffron®.

As with the producing the best wine, suitable soil and climate are essential for cultivating peerless saffron.

Andosol soils represent less than 1% of the world's best ice-free soils and, of those, Japanese Andosol soils are the best in the world: very fertile and young (in geological terms).

Outside Japan, the locations in which almost all of the world's saffron supply is grown is suboptimal for nurturing the saffron plant to reach its full potential.

We strongly recognize the importance of harmonizing and coexisting with this exceptional peerless environment, which leads us not to use chemical fertilizers or pesticides. We only focus on using natural resources to protect the environment and result in safe products for our customers to use.
