AHKAH

A men's jewelry line that AHKAH began developing on a full scale in 2013. In contrast to the main brand, which centered on staple jewelry for women, it brought together men's necklaces, bracelets, rings, and other items under the theme “the gentle man,” while also envisioning unisex wear. Although category names remain on the official website, no products are listed, and in 2015 the brand name was changed to FIVE THIRTY PARK, with the line's development transferred under that name. It is positioned as a historical sub-line that has been discontinued and renamed.

FIVE THIRTY PARK is a unisex jewelry label that emerged in 2015 when AHKAH’s men’s line, “AHKAH HOMME,” was renamed. It pursued designs that cross the boundaries between menswear and womenswear, developing in a minimalist, gender-neutral direction distinct from AHKAH’s delicate fine jewelry. It is currently operated as an independent brand by 青柳龍之亮, but its origins as AHKAH’s official men’s line and its history as a brand derived from AHKAH establish the historical connection between them.

akemiayano was a new brand/global line launched by AHKAH around 2015. Created by 福王寺朱美 and 福王寺彩野, it developed jewelry incorporating Japanese traditional crafts and forms, centered on “modern Japanism,” distinct from AHKAH’s delicate, everyday jewelry. It was carried at AHKAH’s Jinnan flagship store and its Ginza flagship store, and major media also introduced it as AHKAH’s global line. As it does not appear in the current official lineup, it can be positioned as a former spin-off line.

A new jewelry line launched in 2021 by Katie Hillier, who became creative director of AHKAH. Starting from the beauty found in familiar things, it is distinct from the established signature collection, “AHKAH collection,” and continues to present more contemporary, structured designs. It is listed as an independent category on the official website and includes several series, such as chandelier, elements, and ruche. Within AHKAH today, it is positioned as a core line derived from the brand that clearly expresses the creative director’s perspective.

A bridal line developed by AHKAH specializing in engagement and wedding rings. Its focus differs from that of AHKAH collection and AHKAH signature, which handle regular fashion jewelry, and it has a dedicated product range and sales channels centered on engagement rings and wedding bands. In the past, it was developed as a specialty store and bridal collection under the name “AHKAH mariage”; it continues today as “AHKAH bridal” on the official website. It complements the brand family as a specialized line serving bridal demand, separate from everyday jewelry.
