Do you know the difference between Chinese Sansho and Japanese Sansho?

The spice called "Sansho" is a Japanese pepper with a unique scent and spiciness that enhances the flavor your dishes. Today I would like to introduce some basic information about Sansho!

Chinese Sansho vs. Japanese Sansho

Biological differences

Both Chinese Sansho and Japanese Sansho are classified as plants of the genus citrus. There are more than 200 species of plants in the world, and they are all related to the same genus and species, yet they are very different from each other.

⚫︎Chinese Sansho -  A plant native to China called Zanthoxylum bungeanum used for Sichuan pepper and Green Sichuan pepper
⚫︎Japanese Sansho - A plant native to Japan known as Hajikami

Differences in taste and flavor

In contrast to Chinese Sichuan pepper, which has a strong and intense flavor, Japanese sansho is very delicate. Though it depends on the processing method, Japanese pepper, in its powdered form, does not have much of a spiciness but a refreshing flavor that reminds one of citrus fruits. Chinese Green pepper tastes somewhere between Chinese Red pepper and Japanese pepper, though its flavor is a little more like the Chinese Red pepper.

Differences in Usage

Chinese Sansho is mainly used by drying the skin of the pepper seed, but Japanese pepper is used for its flower, seed and leaves. Japanese pepper is processed into "chirimen-sansho" drying its seed, and the seed is sometimes referred to as "Ao-zansho".
It is confusing that "Ao-zansho" is the same kind of pepper as the Green Sichuan pepper (Chinese pepper), but they are not the same thing. The usage of Green Sichuan pepper is basically the same as that of Red Sichuan pepper grinding the dried pepper and sprinkle on or mix into food.

Red Sansho vs. Green Sansho

What is the difference between Red Sansho and Green Sansho?
The green sansho is a pre ripened pepper. The red sansho is harvested after fully ripened and turned into red on the tree. I was confused because I could not tell the difference between Japanese green pepper and the Chinese Sichuan pepper. 

Red Sansho from the Mountain House
What we sell at the Mountain House is Japanese Red sansho pepper.
After the sansho is carefully harvested by hands, it gets dried and sorted into the leaves, branches and seed. This process takes us a several days. 
Once the leaves and branches have been removed, next step is sorting them into the skin and the seed. Finally the seed is ground by a special machine to complete the process.
Although the Red sansho is time-consuming, it is rare in Japan and it is fully ripened flavor.
