ROHTO Pharmaceutical Co., Ltd. (Headquarters: Osaka City, Osaka Prefecture, President: Hidetoshi Segi), its group company Rohto Wellcoat Co., Ltd. (Headquarters: Osaka City, Osaka Prefecture, President: Masanori Kumazawa), and Nissui Co., Ltd.

In this project, a collaborative menu item, "Buri Rohto Donburi," using "Kurose buri" (yellowtail) produced through complete aquaculture by the Nissui Group, will be offered at the Cafe & Restaurant ROHTO RECIPE Umeda NU Chayamachi Plus store from October 10th (Sat) to October 31st (Sat), 2026.

About ROHTO RECIPE x Nissui Collaboration
As digital devices such as smartphones and computers become indispensable to our lives, taking care of our eyes in daily life is becoming increasingly important. As a company that has been involved in eye care for many years, Rohto Pharmaceutical has been promoting the importance of being mindful of eye health in daily life, not just through eye drops.
Meanwhile, Nissui aims to contribute to people's healthy lives through research on food, including marine products, and fish-derived EPA and DHA. October 10th is both "Eye Care Day" and "Fish Day," so this joint project was realized with the desire to combine the expertise of both companies and create an opportunity to think about eye care, including daily eating habits.
In conjunction with this project, Rohto Pharmaceutical and Nissui will also offer original menus using "Kurose buri" (yellowtail) in their employee cafeterias, providing employees with opportunities to think about eye health through their daily meals. Furthermore, on October 10th (Saturday), the "Buri Rohto Donburi" will be offered at "Iga Hyakka" in Iga City, Mie Prefecture, providing local residents with an opportunity to think about health through food.

Brilot Donburi
This limited-time menu features Nissui's "Kurose Yellowtail," known for its rich fat content, combined with a colorful array of ingredients including kale, broccoli, eggs, kiwi, and cherry tomatoes. It's an easy way to consume nutrients such as EPA and DHA, polyunsaturated fatty acids found in Kurose Yellowtail, and lutein and zeaxanthin, found in green and yellow vegetables. The combination of blueberry soy sauce and shikwasa ponzu jelly creates a dish that allows you to enjoy the deliciousness of Kurose Yellowtail and the diverse flavors of the ingredients all in one bowl.
Three seasonal daily deli items, soup
This set includes three seasonal deli items, as offered in ROHTO RECIPE 's regular lunch sets, and a medicinal soup whose ingredients change every two weeks (according to the 24 solar terms). Warming the body with the soup before the meal aids digestion.
- "Spicy chicken breast from Bitchu Plateau and pickled mustard greens with addictive cucumber"
This spicy deli dish features tender Bitchu Plateau chicken breast, the savory flavor of preserved mustard greens, and refreshing cucumber, making it an appetizing treat.
- "Beet and red bean potato salad"
This colorful potato salad combines vibrant beets and red beans, offering a delightful variety of textures and a gentle flavor.
- Sweet potato and purple sweet potato frittata
This frittata is baked to perfection, utilizing the natural sweetness of sweet potatoes and purple sweet potatoes for a vibrant and colorful finish. Sweet potatoes contain nutrients such as beta-carotene and vitamins, while purple sweet potatoes contain anthocyanins. Additionally, it uses "recipe eggs" which contain more lutein than regular eggs.

About Kurose
This yellowtail is produced through complete aquaculture by Kurose Suisan Co., Ltd. (President and Representative Director Sutematsu Tachikawa, Kushima City, Miyazaki Prefecture), a member of the Nissui Group. Complete aquaculture is a complete cycle from artificially collected eggs to raising juvenile fish and then to adult fish, achieving sustainable aquaculture that does not rely on wild juvenile fish. In addition, while yellowtail is generally in season in winter, Kurose yellowtail can be enjoyed year-round, offering the delicious taste of fatty yellowtail in season.
