Running throughout the soul of Kōraru is our love for the ocean. One of the greatest wonders and resources of our natural world, it inspires everything we do, from designing pieces that complement its beauty, to producing in a way that conserves its precious ecosystems and marine life. 

Our core collection of swimwear staples is a celebration of simplicity. Comprising three bikinis and a one-piece, each style has been designed thoughtfully to utilise classic shapes, clean lines and a versatile colour palette, ensuring contemporary yet timeless appeal. Made from ocean-friendly regenerated fibres, attention to fit and comfort means they look as good as they make you feel. Every piece from our sustainable swimwear collection is something to cherish in your wardrobe for years to come. 

When naming the collection, we felt passionate about giving Kōraru’s four signature silhouettes names that evoke the ocean. Looking as beautiful to the eye as they sound to the ear, RIFU, NIKKO, KUMANOMI and CHIKYU all relate to elements of our blue planet, embodying our core values and speaking to our deep-rooted affinity with Japanese lifestyle.

RIFU - The Reef: providing essential shelter and sanctuary to marine life big and small.

The RIFU bikini top is a play on the classic triangle cut and comes with tie-up straps that can be effortlessly adjusted to find the perfect fit. The coordinating briefs have been purposely designed with ample coverage to allow them to be worn either on the hip or high-leg. Lines are minimal for uninterrupted tanning.

NIKKO – Sunlight: the source of light and life on which our natural world thrives 

The NIKKO bandeau top can be worn with straps for a timeless vintage-inspired appeal, or without for a minimal sunbathing-friendly look. Curved lines create a beautiful silhouette and ensure the top doesn’t roll down, while soft, non-wired cups and light padding offer gentle shape and support. High-waisted briefs that elongate the leg and offer stylish coverage, complete the flattering yet functional set.

KUMANOMI - Clownfish: the reef-dwelling fish renowned for its striking beauty 

Taking inspiration from a classic balconette, the KUMANOMI top is cut to sweep across the bust and offer elegant support. Our signature double strap creates an elongated line and adds a contemporary twist to the timeless silhouette. Perfectly simple, the complementing mid-rise, medium-coverage briefs finish the polished, streamlined look.   

CHIKYU - The Earth: The sacred land we call home. Our mother.   

Striking the perfect balance between style and comfort, our CHIKYU one-piece swimsuit has a full-coverage front conterpointed with a revealing low-cut back. The contemporary square neckline – evocative of our KUMANOMI silhouette – is set off by wide straps which are designed to stay up, even when swimming. A high-cut elongates the leg line, while the chic tie belt flatters the waist and can be worn knotted at the front, side or back to complement your cover-up. The ultimate forever-swimsuit.
