Shou sugi ban is the trademarked name, but a lot of people use this term because that's the name they've heard. Yakisugi is the term for the technique if I remember correctly. But it is absolutely beautiful, you can find some lovely examples of outdoor furniture with this method alone and with combining yakisugi and colored wood stain.

I had not heard that term but yes you are right, thank you! I knew it was taken from a older technique by my brother and modified for my use now I know the origin!
