Frequently Asked Questions

Our favourite model from Japan Blue are the the J501 which stand out as an iconic representation of Japan Blue Jeans' commitment to quality and craftsmanship. Crafted from the flagship 14.8oz US cotton selvedge fabric, these regular straight jeans feature a suite of signature details: a vegetable-tanned leather patch, a royal blue inseam, and a branded doughnut-shaped top button, encapsulating the brand's dedication to excellence. Made from durable American cotton, the jeans are designed for longevity, with a warp yarn that is rope-dyed in deep indigo for fades with distinctive contrast over time. The fabric, woven on vintage shuttle looms and sanforized for minimal shrinkage, offers a robust finish and comfort post-wash, exemplifying Japan Blue Jeans' mastery in denim creation.

Japan Blue Jeans are designed with standard sizing to ensure a perfect fit for customers. We recommend selecting your usual size for the best fit, but it's always wise to consult the size chart provided on our website to find your exact size. The jeans are made from sanforized fabric, which means they have been pre-shrunk to minimize shrinkage after purchase. However, it's typical for sanforized denim to stretch slightly with wear, so you can expect about 0.5 to 1 inch of stretch in the waist over time. This natural stretching process helps ensure that your jeans will conform comfortably to your body, offering a personalized fit as they age. For care, following the specific washing and maintenance instructions provided with your jeans will help preserve their quality and longevity, allowing you to enjoy the distinctive characteristics of your Japan Blue Jeans for years to come.

Japan Blue Jeans delivers the same high-quality Japanese denim at a more accessible price point because they are directly integrated with Collect Mills, Japan's leading denim fabric wholesaler. Being part of the same company allows Japan Blue to utilize premium denim materials without the added costs typically associated with middlemen or external suppliers. Japan Blue and Momotaro Jeans are also part of the same family with both brands having a slightly different offering.
