Local Long-Standing Seafood Company Changes Sales Channels on TikTok Shop -- Yamani Noguchi Suisan in Rumoi, Hokkaido Exceeds 20 Million Yen in Cumulative Sales Within 5 Months of Launch

KASHIKA Inc. (Head Office: Ota-ku, Tokyo; President: Kenta Ozawa) is pleased to announce that Yamani Noguchi Suisan Co., Ltd. (Rumoi, Hokkaido), which utilizes the SNS operation support tool "2nd Buzz" (https://2nd-buzz.com/sns-solution/) for its TikTok operations, has surpassed 20 million yen in cumulative sales on its TikTok Shop within just 5 months of its launch. Furthermore, the company achieved 20 million yen in cumulative sales approximately two months after reaching 10 million yen, indicating an accelerating growth rate.

Growth Trajectory -- Cumulative Sales Exceed 20 Million Yen Within 5 Months of Launch

Yamani Noguchi Suisan launched its TikTok Shop on February 8, 2026. In its first month, February, sales were 1.18 million yen, followed by 5.12 million yen in March. Cumulative sales surpassed 10 million yen on April 22, the 73rd day after launch. The company continued to grow, achieving cumulative sales of 20 million yen within 5 months.

This figure significantly exceeds the total sales from Yamani Noguchi Suisan's existing EC sites such as Amazon and Rakuten, signifying that TikTok Shop has become the company's largest sales channel.

2nd Buzz's Buzz Analysis Boosts Sales Growth

One of the factors supporting this sales growth is data-driven operation utilizing "2nd Buzz," a food SNS operation support service provided by KASHIKA.

2nd Buzz analyzes metrics such as video views and engagement data using its proprietary service. By understanding the commonalities of content that resonates with the market, they design campaigns and produce content that is more likely to be accepted by viewers.

Yamani Noguchi Suisan implemented a three-pronged approach: continuously posting short videos conveying the atmosphere of the processing plant and the appetizing appearance of products (organic strategy); collaborating with approximately 160 creators focused on the "evening drink" and "gourmet" genres (performance-based affiliate marketing strategy); and promoting high-performing content as TikTok Shop ads (advertising strategy).

As a result, organic content accounts for a large portion of sales, achieving efficient sales growth while minimizing reliance on advertising.

Purchasing Data Reveals New Sales Channel

The primary customer demographic is 25-34 years old, with men constituting the majority. Geographically, about half of the purchasers are from the Tokyo metropolitan area, primarily Tokyo, Saitama, and Kanagawa prefectures.

A key feature of this case is the establishment of a structure where processed seafood products manufactured in Rumoi, Hokkaido, are continuously sold to young consumers in the Tokyo metropolitan area through TikTok Shop.

This case demonstrates a shift in sales methods for regional food products, having built a new sales channel with demographics that were difficult to reach through traditional search-based EC.

The Era of Regional Food Sales Shifts from "Being Searched For" to "Being Discovered"

This case is not just a success for one company, but indicates that the sales channels for regional food products themselves are beginning to change.

While it was traditionally common to "search for and purchase" products through search engines or EC malls, "Discovery Commerce," where purchases are made through accidental encounters with video content, is becoming established as a new sales model on TikTok Shop.

The case of Yamani Noguchi Suisan exemplifies the potential for even regional companies to directly deliver products to consumers nationwide, regardless of their region or name recognition, and is expected to lead to new sales models for regional food products in the future.

Future Outlook

KASHIKA plans to expand the successful "2nd Buzz Buzz Analysis x TikTok Shop" model, proven by the Noguchi Suisan case, to other businesses, particularly food manufacturers. They will provide data-driven, reproducible operational support to small and medium-sized food businesses facing challenges in expanding their sales channels using SNS.
