Japan Blue Jeans

The Collect Mill of Kojima, Okayama produces some of the finest denim in the world. Japan Blue uses this material, telling us that “Material is a key factor to determine the quality of jeans.” Following the age-old tradition of artisanal denim-making, in 2010, the designer of Japan Blue Hiroki Kishimoto set out to do this for the modern customer. Collect manufactures denim for some of the finest companies in the world and Japan Blue knew it needed to follow suit. The result ultimately manifested itself in being jeans made in more modern, simpler cuts with the same fabric, focused on the weaving, the yard, the dying, the fabric itself.

Japan Blue JB0412S Sizing Guide

How to measure

Follow this easy sizing guide to locate your size on the chart below. Message us at if you had further questions.


Place your flexible tape measure inside the waist of your favorite pair and measure along it. Use paper clips or clothes pins to keep tape close to the inside of waistband as possible. This eliminates any gaps along the outside of the jeans and gives you your perfect waist measurement.

Front Rise:

Lay your jeans on the ground and measure from the crotch seam to the top of the front waistband.

Back Rise:

Lay your jeans on the ground front side down and measure from the crotch seam to the top of the back waistband.


To find your thigh measurement, take the tape from the crotch (not from the crotch seam but the edge closest to the side you are measuring ) and measure directly to the side of the leg.


To find your inseam length, lay your jeans on the ground and measure from the crotch seam to the hem.

Leg opening:

Measure the bottom of the jean’s hem from side to side.
