iroha introduces the iroha koharu Suiren

iroha, the women-led sister brand of TENGA, introduces the iroha koharu SUIREN, a limited-edition collaboration with brand ambassador and cultural icon Kiko Mizuhara. Inspired by the water lily (‘suiren’ in Japanese), the SUIREN reimagines iroha’s slimmest insertable product in a serene pastel-purple shade. With its compact, flower-bud design, flexible tip, and intuitive dial control, it is crafted to ease anxiety around penetration and support both first-time users and those who want to rediscover their pleasure later in life

The iroha koharu’s slim and beginner-friendly shape reduces anxiety around penetration while still offering effective internal and external stimulation. Its flower-bud tip flexes to follow the body’s contours, making insertion feel gentle and intuitive – qualities that make koharu suitable for people at the beginning of their pleasure journey, at any stage of life.

Kiko Mizuhara, who has served as an iroha ambassador since 2023, worked closely with the iroha team on color selection and finishing touches for this limited edition. The chosen lilac tone complements the existing koharu palette and reflects the water lily’s meaning of trust – a fitting symbol for a product designed to foster comfort and ease.

The koharu SUIREN features a smooth dial for seamless vibration control, from gentle to powerful, as well as a waterproof body for use in the bath or shower, and an anti-dust silicone coating for easy cleaning. Powered by a single AAA battery, it offers up to four hours of playtime to encourage relaxed, unhurried exploration.

“The iroha koharu SUIREN is the perfect introduction for people beginning their sexual journey, or for anyone who wants a non-intimidating way to explore insertion, ” says Rika Adachi, Global Marketing Manager at iroha. “With its slim shape, soft touch, and beautiful purple color, the koharu SUIREN is designed to help users feel comfortable and confident, whether they are just starting out on their pleasure journey, or rediscovering it.”
