Story of Us

1998, In the very beginning, we moved to Miyako island from Fukuoka, rented a 50-year-old vacant house started a bead accessory maker called King and Queen. Bead accessories were placed at hotels and souvenir shops on Miyako island.

We saved money and opened a small clothing store on the first floor of an apartment in Hirara in 2000.

At the same time, we started selling Fucoidan, healthy foods, and Miyako island local products on the website. Since the internet was still dial-up and there was no shopping cart function, the products were sold via e-mail or telephone.

In 2005 we returned to Fukuoka, established the company name King and Queen International, we started to run several clothing stores in the suburbs of Fukuoka until 2016.

Because our sons had been also tennis players dreaming to become professionals, we lived in Kurume, Yufuin, Hakata, and California in the United States to have tennis matches every weekend.

In 2016, we integrated multiple stores into Mochihama and closed it in 2018.

We changed the name of the company to worldpeace Inc. same as our domain, changed our nature of business from importing clothing and retailing them to IT-related business such as making websites and Designs.

In 2018, we run into Yamecha and has been focusing on promoting Yamecha in earnest not only in Japan but also around the world.

In 2019, opened an office in Miyaki-cho, Miyaki-gun, Saga Prefecture.
