Muji started with only 40 products in the 1980s. Some of their products include pens, pencils, notebooks, storage units, apparel, kitchen appliances, food items, and household care products. Muji has also created an automobile. Muji storefronts such as the one in New York are large and stocked with nearly every single product available. The primary business also includes Café Muji, Meal Muji, Muji Campsite, florist and home furnishing; the company has also engaged in architectural projects such as Muji House.
By the end of the 2000s, Muji was selling more than 7,000 different products. It is positioned as a “reasonably priced” brand, keeping the retail prices of products “lower than usual” by the materials it selects, streamlining its manufacturing processes, and minimising packaging. In April 2019, Muji opened its largest Muji store in Ginza, Japan
