Inspired by the magnificent Sea of Clouds surrounding Mount Fuji, Unkai captures the tranquil beauty of one of Japan’s most iconic landscapes.

The series’ signature bi-colour design is inspired by Mount Fuji’s mountainside as it quietly reveals itself in the clear early mornings of autumn and winter, illuminated by the rising sun. Complementing this, the transparent barrel features intricate guilloché engraving, lens-cut facets and finely carved grooves that recreate a shimmering sea of clouds, changing beautifully with every angle of light. Paired with the translucent brown-toned cap and grip, the pen achieves a refined and harmonious composition that conveys both lightness and sophistication.

At its heart is a rhodium-finished 14K gold nib, available in Extra Fine, Fine and Medium, delivering the smooth and precise writing experience for which Platinum is renowned. Each pen is individually serialised with a Mt. Fuji-inspired domed finial and presented in an exclusive gift box, accompanied by a commemorative 20ml bottle of Fuji-no-Ebizome ink, inspired by the twilight hues of Mount Fuji.

Limited to just 1,500 pieces worldwide, Fuji Unkei “Unkai” is a fitting finale to one of Platinum’s most admired collections—an elegant tribute to the timeless beauty of Mount Fuji and the artistry of Japanese craftsmanship.
