Eisai Co., Ltd. (Headquarters: Tokyo, CEO: Haruo Naito, “Eisai”) announced today that the digital tool for self-assessment of brain performance (brain health) “NouKNOWTM” (pronounced “NOH-NOH”, non-medical device), which Eisai has launched in Japan, is to be expanded in the fixed-rate membership beauty salon “Attina”, which is operated by Youforio Co., Ltd. (Headquarters: Tokyo, President: Seiji Okubo, “Youforio”).


In recent years, various research has demonstrated the possibility that decline in brain health may be mitigated through readjustments to lifestyle such as regular exercise and a well-balanced diet. However, according to a survey conducted by Eisai, few people correctly understand the importance of or habitually perform such preventive actions and assessments of cognitive function; this indicates disparities (“chasms”) which exist for incorporation of such habits into daily lifestyle.


Eisai is engaged in efforts for the habituation of self-check and prevention activities for maintenance and improvement of brain health through “NouKNOW” in order to overcome chasms, and intends to build a wide range of places in which regular brain performance checks are possible. It can be expected that use of this tool to perform periodic self-assessments about brain performance among the generation currently in their prime working years will create an opportunity for re-consideration of daily lifestyle, greater preventive measures, and consultation with healthcare professionals and others. Eisai considers beauty salons to be one of the very effective places (health bases) for regular brain performance checks with “NouKNOW”, as post-check follow-up is possible based on existing trust relationships with customers and regular visits are predictable.


Seiji Okubo, President of Youforio, said “We believe that ‘beauty and health’ are essential for realizing our management philosophy of ‘people becoming lively through beauty.’ Eisai’s daily efforts as a pharmaceutical company towards extending healthy life expectancy of the population resonated with us, and we have decided to work together to realize the conversion of beauty salons into health bases. Through performing brain performance checks in beauty salons, we aim to extend healthy life expectancy, and establish the beauty salon of a new era as a place where one may attain not only beauty but also health.”


Based on the concept of ‘conversion of beauty salons to health bases’, in addition to the offering of beauty salons as places for regular brain performance checks Eisai aims to continue the expansion of “NouKNOW” to health checkups conducted by municipalities and corporations, as well as a broad range of customer contact points including care facilities and fitness clubs, while planning the habituation of cognitive function checks in daily life.


Eisai aims to construct a dementia ecosystem platform for connecting everyday life and healthcare, and thus realize innovation that changes society.

1. About “NouKNOWTM

Name: “NouKNOW” (pronounced “NOH-NOH”) *”NouKNOW” is not a medical device.


“NouKNOW” is a cognitive function test created by Cogstate, Ltd. (Headquarters: Australia, “Cogstate”) for which Eisai holds the rights for exclusive development and commercialization in Japan. It is conducted through a simple card test using a PC or tablet device to quantitatively measure brain performance in four tests evaluating psychomotor function, attention, learning and memory, and working memory. This digital tool allows users to self-assess independently and in a short time frame (approx.15 minutes), enabling regular assessments in instances such as daily life and health checkups. Eisai is currently selling this tool to legal entities such as municipalities and corporations. In addition to Youforio, the usage of NouKNOW has been decided for other partners including Kajima Corporation.
