KAITORU Inc. Fully Renovates Website for Its Buying Brand "Tsunaguya"

KAITORU Inc. (Head Office: 1-11-12 Hatchobori, Chuo-ku, Tokyo; Representatives: Kyohei Matsueda, Takuya Morimoto; hereinafter "the Company") announced the renewal of the official website for its service brand "Tsunaguya" (https://tsunaguya.co.jp/) in June 2026.

Having grown to approximately 40 employees in just over three years since its establishment and accelerating its service expansion nationwide, the Company has revamped the brand image of the "Tsunaguya" official website, which serves as the initial point of contact with customers, to align with its business expansion phase. The design has been refreshed with a substantial feel based on a Japanese aesthetic, and information on buying methods and items has been reorganized. The site has been restructured to communicate our services more clearly to customers.

Background of the Renewal

Under the brand name "Tsunaguya" and with the concept "Connecting Your Treasures to the Next Smile," the Company has been developing its business primarily through event-based buying at supermarkets and commercial facilities nationwide. In just over three years since its establishment, the company has grown to handle over 100,000 appraisals annually (cumulative from May 2025 to April 2026), with the pace of service expansion accelerating year by year.

In line with this business expansion phase, we have fully renewed the "Tsunaguya" official website to communicate our services more accurately and clearly to our customers.

Key Points of the Renewal

1 Revamped Design with a Renewed Brand Image

The design has been renewed with a Japanese aesthetic to more impressively convey the brand's reliability and expertise. We have adopted a visual expression that combines calmness and a sense of luxury, allowing customers to entrust their precious items with peace of mind. The structure is designed to convey the brand world of "Tsunaguya" even to first-time visitors.

2 Clear Organization of Three Buying Methods

We clearly present three methods: buying at event venues, online appraisal via LINE, and in-home buying, offering options tailored to the customer's lifestyle and situation. In particular, the LINE appraisal service provides results in as little as 10 minutes just by sending photos, making it easy for busy individuals or those who cannot visit in person.

3 Enhanced Content on Market Prices and Buying Information

We update reference buying prices for gold (K24-K5), platinum, silver, and palladium daily, and have prepared detailed pages for each item category, including jewelry, watches, brand-name goods, gold/precious metals, cameras, and alcoholic beverages. We also disclose actual reference buying prices to create an environment where customers can make informed decisions about selling with confidence.

Future Developments

With the concept "Connecting Your Treasures to the Next Smile," the Company will continue to expand its buying services nationwide, connecting customers' precious items to the next generation. Through the new "Tsunaguya" official website, we are continuously accepting inquiries about buying and applications for LINE appraisals.

Comments from Representatives

"Through our buying business, we have encountered truly countless 'treasures' from our customers. Jewelry that had been stored in the back of a closet for years, watches inherited from loved ones, collections gathered since childhood—we approach our work with the feeling that each item holds irreplaceable memories and stories.

As a result of these daily efforts, our business has grown in scale year by year. With this growth, we feel an increasing responsibility to properly communicate who we are to our customers. We hope that this website renewal will serve as an opportunity for more people to learn about the 'Tsunaguya' brand and to visit our events or physical stores."
