Rohto Pharmaceutical Co., Ltd. (Head office: Osaka City, Osaka Prefecture, President: Hidetoshi Seki) will launch 'Eu Yan Sang Chicken Essence (Keijitou)' on the Rohto online store on Monday, April 20, 2026, under the Eu Yan Sang brand. Additionally, 'Eu Yan Sang Reishi' and 'Eu Yan Sang Bird's Nest' will be released on Monday, May 11, 2026, delivering a new self-care option of dietary nourishment to Japanese lifestyles.
This product lineup proposes a self-care habit of 'nourishing the Vital Origin (source of vitality).' Following 'Eu Yan Sang Cordyceps' released as the first phase in March 2026, this provides new options to choose from depending on the ingredients and lifestyle scenes.
■ Background of the Release
In modern times where stress and irregular lifestyles persist, there is a growing interest in 'pre-disease prevention'—adjusting one's condition through daily diet and lifestyle, rather than dealing with symptoms after they appear. Our company, originating from gastrointestinal medicine, has long supported consumers' health in the internal medicine sector. In recent years, as a 'pharmaceutical company that doesn't rely solely on medicine,' we have been focusing on 'food' as one of the options to support daily well-being, in addition to responding after symptoms appear.
In East Asia, the wisdom of 'dietary nourishment'—incorporating ingredients and traditional materials into daily life to adjust condition while observing the overall balance of the body—has been passed down. Through the Eu Yan Sang brand, which has delivered such wisdom, we are proposing the concept of 'nourishing the Vital Origin' tailored to Japanese lifestyles. 'Nourishing the Vital Origin' is the concept of taking in the survival power possessed by ingredients to support the inherent power of human beings. Rather than just supplementing specific components, we value delivering the wisdom of traditional materials in a form that is easy to incorporate into daily life.
In the Japanese market, 'Eu Yan Sang Cordyceps,' launched as the first product in March this year, has been well received as the first step in self-care habits for those aiming for healthy daily lives (limited release from January). In this second phase, we will release 'Eu Yan Sang Chicken Essence,' 'Eu Yan Sang Reishi,' and 'Eu Yan Sang Bird's Nest' as a lineup that makes the concept of dietary nourishment feel more familiar. By expanding the concept of dietary nourishment as a product group with different ingredients and ways of incorporation, we propose new options for adjusting daily condition.
■ Focus on Ingredients
● Chicken Essence
Nutrients extracted from the chicken itself have long been noted overseas as being exceptionally good for health. It is widely used by everyone from small children to seniors when concerned about nutrition or wanting to maintain energy. It is characterized by tightly concentrated nutrients and low fat content.
● Reishi
A type of mushroom that has long been used as a nourishing ingredient in China. It is prized for protecting the body from various environmental changes, and the spore part, in particular, is considered even more precious as its harvesting period is very short.
● Bird's Nest
It has been highly prized since ancient times as a beauty and nourishing ingredient. It is a rare ingredient containing glycoproteins, sialic acid, and more. Sialic acid is a component found abundantly in breast milk, especially colostrum.
■ Product Features
● Eu Yan Sang Chicken Essence
Uses only chicken, without any flavoring such as water or salt. It moves to the extraction process within 30 minutes of processing, undergoes high-pressure extraction slowly over 8 hours, and condenses the essence into one pouch. It is a traditional nourishing food familiar in Taiwan as a gift for students preparing for exams or for postpartum care.
● Eu Yan Sang Reishi
Uses Reishi, known as a traditional ingredient. One grain contains 240mg of cell-wall broken Reishi spore powder and 60mg of Reishi extract powder. The cell wall of spores is hard, making it difficult to extract the nutrients inside, but Eu Yan Sang breaks the cell wall of the spores and innovates the delivery method.
● Eu Yan Sang Bird's Nest
Uses cave bird's nest from Malaysia. The ingredients are only 'water, bird's nest, and rock sugar.'

■ Future Developments
Going forward, our company will clearly deliver the wisdom of dietary nourishment cultivated by Eu Yan Sang to Japanese consumers, including not only products but also how to incorporate them and the concept of nourishment. We aim for the culture of 'gifting health,' which Eu Yan Sang has cherished—where the daily habit of tuning one's own condition eventually leads to actions caring for those close to them—to naturally spread in Japan through products, information dissemination, and various proposals.
We will continue working toward the realization of well-being in the coming era while integrating the wisdom of Eu Yan Sang's traditional ingredients with the science and consumer perspectives our company has cultivated.
