Oni Denim is a small scale production – it was brought to the attention of consumers outside Japan mainly due to it’s association with Blue in Green Soho. Here is what Hinoya has to say about Oni (I’ve corrected the grammar & rephrased it for clarity):
“Oni Denim production relies on only one old workman.
If it is not handled by this old, experienced workman, the machine that weaves
the cloth of Oni Denim cannot function well.
This old craftsman is nearly 80 years old.
Only this old man can make the fabric used in Oni denim now.
It is very time-consuming to make Oni Denim – the available models will be sold out soon!
Masterpiece of craftwork.
It is ONI DENIM.”
Here’s some Oni love: 18 oz, slubby denim on the ‘Ghost Armour’ jeans.
