Sushiro

Sushiro is currently the largest conveyor belt sushi company in turnover. It has more than 500 restaurants in Japan. The first overseas branch opened in Seoul, South Korea. In 2017, Taiwan Sushiro Co., Ltd. was established. On 15 June 2018, a Sushiro shop was opened in Taipei. In August 2019, it opened a branch in Hong Kong. In the same month, it opened its first branch in Singapore. In March 2021, the first Sushiro location in Thailand opened in Bangkok. In September 2021, it opened its first chain in mainland China, in Guangzhou. In November 2023, Sushiro Indonesia began operations at its first branch in Jakarta. Subsequently in April 2024, it was reported that Sushiro has set up a local company in Malaysia to consider its business expansion in the country, with the first outlet opened on 7 February 2025.

Japan

A Japanese Consumer Affairs Agency report released in June 2022 accused Sushiro of false advertising, by claiming a "limited offer" of sea urchin and crab sushi while having no stock of these in most stores.

On 29 January 2023, a video emerged showing a 17-year-old student at Sushiro’s Gifu Masakiten licking a soy sauce bottle and a cup before returning them, sucking his finger, and touching sushi moving along the conveyor belt. This caused the stock price of Food & Life Companies, the parent company of Sushiro, to plummet. Its market value lost more than 16 billion yen. In August, Sushiro dropped its lawsuit against the student, saying that he admitted his "responsibility" and reached a "reasonable" agreement. His attorneys argued that the decrease in customers could have been due to competition from other restaurants.

Taiwan

At the beginning of 2021, a two-day promotional event by Sushiro in Taiwan promised to serve free sushi to people with the word "salmon" in their name. This caused multiple Taiwanese people to change their names to include the word "salmon", an event the media dubbed "salmon chaos".

China

Multiple Sushiro chains in Guangzhou, China came under fire for linguistic discrimination after the chain's supervisors banned the Cantonese language between employees on its online chat groups. Sushiro later apologised, amid local boycotts.
