Noticed this last week on the BBC website, but didn't see a mention here:

A designer has created a tartan for Japan which draws inspiration from the country's fascination with cherry blossom and a Scottish industrialist.

David McGill, from Edinburgh, has previously designed tartans for Poland, France and Norway.

His latest design has still to be woven, but on paper includes the colours pink, white, green and brown.

While researching the design, he looked into the story of Fraserburgh-born Thomas Glover, the "Scottish Samurai".

The new tartan has also had input from Shizue Melvin, from Japan, who is married to a Scottish businessman.

The design is called sakura, Japanese for cherry blossom.
