Astellas Pharma Guideline for web accessibility

Astellas Pharma is planning/creating Websites by considering accessibility, in order to ensure ease of use by as many site visitors as possible.

What is accessibility?

Accessibility means that anyone browsing the Website can access the information on the site and use the contents and other functions without problems. In particular, the word is used in terms of whether the Website is user-friendly for the elderly and physically disabled, who encounter obstacles when browsing Websites.

Astellas Pharma's idea on accessibility

Astellas Pharma, providing ethical pharmaceuticals, believes that it is its social responsibility to construct a Website easily used by patients including elderly and physically disabled people and their families, and which has information worth browsing on it.
Our company upholds the business philosophy (raison d'etre) to "contribute toward improving the health of people around the world through the provision of innovative and reliable pharmaceutical products." We also understand that in terms of putting this business philosophy in practice, it is important to ensure accessibility for visitors to the site who need information on diseases as well as various information about Astellas Pharma.

Considering accessibility

Based on the ideas mentioned above, Astellas Pharma prepared an original web accessibility guideline based on the official guideline (*1). All staff in charge of web creation will plan and create content, as well as implement operation and verification for accessibility quality control, based on this guideline. (*2)
Although the Website operating currently includes some contents created before the preparation of the guideline, we will try to improve and update these contents one by one. We continuously aim to provide a more user-friendly site in the future.personal information, then please contact us using the contact details provided at the bottom of this Privacy Notice.
