What stands out

Handles design, manufacturing and retail in-house, from engagement and wedding rings to jewellery and watches
Revenue rose from 6.66 billion yen in the year to September 2024 to a record 7.00 billion yen in the year to September 2025
Offers Disney-design products and pure gold and 18-carat gold items for fans, using licences from anime, games and more

What could go wrong

In the year to September 2025 a surge in raw material prices and higher advertising and sales commission costs cut net profit from 166 million yen the year before to 23 million yen, even though revenue rose
When gold and platinum prices rise, material costs go up and squeeze profits; the gross margin for the first three quarters of the year to September 2026 was also lower than a year earlier
In the year to September 2026, net profit for the first three quarters was only 6 million yen, about a third of the same period a year earlier, while the full-year company forecast is 78 million yen

About the company

A jewellery company strong in made-to-order pieces, handling everything from design to manufacturing and retail for engagement rings, wedding rings, other jewellery and watches.

How it makes money

It sells engagement rings, wedding rings, jewellery and watches through its own stores across Japan, and besides made-to-order pieces tailored to each customer it also remodels and repairs jewellery. It carries Disney-design bridal rings and jewellery as well. It is putting effort into licensed goods for fans of anime, games and VTubers, and at its subsidiary U-Treasure items such as pure gold coins and 18-carat gold figures have been popular. Some production is done at a subsidiary in Thailand, and from the year to September 2025 it began selling in mainland China.

Where growth is meant to come from

The company aims to grow sales through the price revision it made in April 2026, rising sales of licensed products, and OEM sales of items made under other companies' brands. Its forecast for the year to September 2026 was revised in May 2026 to revenue of 7.91 billion yen and net profit of 78 million yen, about 3.4 times the previous year.
