Description

Debut in 2012, the flagship ONI “Secret Denim” quickly gained popularity among denim enthusiasts globally for its distinctive texture and remarkable softness. It provides a rewarding fast and unique fading pattern while offering an unmatched level of comfort at the same time. The “”Secret Denim “has reached the pinnacle in the Japanese artisanal denim world. It has made its way through the vast world of denim wholly by word-of-mouth. 

While vintage Levi’s utilize number 6x7 yarn for their denim, the “Secret Denim” uses 3.7x3.7 extra extra thick yarn. The origins of the yarns actually come from 3 different type of cotton mix. Woven at ultra-low tension on a vintage shuttle loom. The result is a beefier, extremely knotty unsanforized 20oz fabric with a fantastic slub, roughness and hairy texture. The warp is roped dyed with ONI’s secret recipe for a uniquely tinted blue expression. The weft is meticulously tuned to a beige color to compliment the special blue tone on the front of the fabric.

It is one of the most sought after/recommended 20oz denim. For someone who would like to try a ultra heavy denim, this would be the perfect entry and destination for some. Even if you can’t bear a heavyweight denim in summer. This is still a popular and easy option to fade in winter!

This year, the Secret Denim comes with ONI’s popular Kabuki selvedge ID, to commemorate the 14oz natural indigo kabuki selvedge denim and the 22oz natural indigo kabuki selvedge denim (in reality it is 24oz) made 20 years ago. The Kabuki selvedge ID then becomes popularized and is deemed as one of the ONI’s signature details.

"The Rebirth of Secret Denim"

In truth, ONI has produced three different versions of Secret Denim over the past decade. After the first version gained extreme popularity, its yarn supplier unfortunately went out of business following a devastating fire caused by a natural disaster. For a long time, it was believed that the original texture of the first Secret Denim could never be recreated.
   
As a result, the versions of Secret Denim ONI produced for quite some time were not made using the "original formula."

But in 2024, Mr. Oishi managed to find a new yarn supplier capable of spinning yarns that closely resembled that of the original. Thanks to that, the mysterious character of Secret Denim was finally brought back to life, letting us once again experience the magic that made it a sensation in the first place.

“The denim does have a hefty hand at the beginning. But it does not feel uncomfortable at all at the beginning. Some might share that it feels like sweatpants after several wears to several weeks of break-in.”

– Sven, Store Manager

“Even if I gave some manufacturer the recipe of this denim, they are unable to replicate what you see here.”

– Mr. Oishi

ONI 200 fit

ONI 200 fit seat on a sweet spot between the popular regular straight like 288 & Wide straight jeans like 222. With the traditional configuration of high waist and wide straight legs, 200 fit focuses on the classic appearance, and cancels the N-shaped brand pocket arcuate design on the back pocket. The plain fabric makes the appearance more minimalistic, and at the same time strengthens the matching possibilities with various items and styles. The wide trousers provide enough space for movement, which can effectively reduce the discomfort caused by humidity and heat in Taiwan's subtropical climate. If you're wearing this in a dry climate, it will give you an unprecedented experience if you are new to wide jeans.

How much does ONI 'Secret Denim' stretch in the waist?

ONI Secret Denim will stretch out fairly fast so you can expect it to stretch at least 1 inch after first day to 1 week of wear. It will stretch up to 2 inch in the waist with about 30 wears.

ONI jeans general size recommendation

Go up at least 2 sizes from major US brands. Usually the same or go down 1 size from other Japanese brands.
