It’s time to ditch fast fashion with these sustainable fashion brands in Japan.

Today, more people are opting for slow fashion over fast fashion. Slow or sustainable fashion brands in Japan and the rest of the world do things differently. Their clothing might seem more expensive than that of fast fashion brands, but let’s take a closer look at the real cost.

Why You Shouldn’t Buy Into Fast Fashion

Fast fashion might appear cheap, but why? The companies may cut corners when sourcing raw materials, pay their workers poorly, or pollute the natural environment.

Just one look at the massive landfill at Korle Lagoon, Ghana, confirms that the dumping of fast-fashion clothes is environmentally hazardous. Not only that, but fast-fashion can sometimes be deadly. The Rana Plaza disaster in Bangladesh in 2013 is just one example of the humanitarian cost of the fashion industry.

Unlike fast fashion, sustainable fashion brands do not emphasize mass production and cutting costs to maximize profits. Instead, they focus on:

  • Using natural materials for fabrics, buttons, dyes and thread
  • Using organic materials that are pesticide-free 
  • Making durable and versatile clothes that can be repaired or redyed
  • Producing biodegradable clothing
  • Having a lower impact on the physical environment
  • Protecting animal welfare
  • Protecting and paying workers fair wages
  • Encouraging fair trade and the development of local communities, especially in the Global South
  • Providing a transparent supply and distribution chain

Liv:ra makes lingerie from organic cotton and silk. Pieces are hand-dyed with plant-based dyes, using the Kyoto shin manyo technique. Because the skin is considered the largest organ, this company uses safe, natural dyes that will not disrupt the body’s internal systems. The brand also offers a redye kit so you can spruce up that lingerie anytime.

7. Kapok Knot

Kapok Knot

This brand uses kapok fiber, which comes from the kapok nut. Nut production uses little water or pesticides. Kapok Knot makes light and warm jackets, coats, blankets and more. Unlike traditional down jackets, which use bird feathers, kapok production does not harm any animals.

They use natural fibers like organic cotton (including recycled cotton), merino wool, washi paper and hemp. The company also offers transparency throughout the supply and distribution chain.
