Shop BLUE BLUE JAPAN kids' collection with price comparison across 500+ stores in one place. Blue Blue Japan got its start in 1996 as the in-house brand for Okura, an American clothing shop in Kobe. Currently based in Tokyo, Blue Blue Japan’s line of menswear delivers a Japanese interpretation of American denim. With traditional Japanese craftsmanship and an affinity for the iconic indigo blue of classic denim styles, Blue Blue Japan offers a vibrant selection of crisp button-downs, pants, and t-shirts in stimulating prints and relaxed knits. Artisanal washing and dying processes distinguish the line’s harmonic, painterly aesthetic.
