We aim for...

A society where people don't need to be "normal"

Where each person, regardless of neurotype, can live their life happily

We are the first Japanese NPO dedicated to promoting Neurodiversity, consisting of members with various neurotypes

For organizations and companies working on neurodiversity

We aim to realize neurodiversity through various means, referring to papers and initiatives worldwide. And we are also engaged in our own projects such as the Pattern Language Project.
However, since there is still little information in Japanese on neurodiversity and efforts in Japan have just begun, we are looking for international partners. If you are interested, please send an email to common@dioden.org.

We aim to create a society where the diversity of neurotype is celebraed
...What we like to do and what we don't like to do
What kind of method and what kind of environment suits us
What we are good at and what we aren't
The degree to which we like, the degree to which we are good at,
and Even the extent to which we dislike it and the extent to which we are not good at it
Each person is really different

However, in most cases, there is only a way of life which is regarded as "normal" * .
And people who are different from those around them are...

Forced to try to fit in with those around them. or...

Only when you can't work in the current environment and methods, Apply to be certified as "developmentally disabled" (Some neurodivergents are not eligible)

However, is the way of being and environment that is currently considered "normal" the only "correct" one?

Are we an "unavoidable sacrifice" even in today's world where not only being "everyone is the same" but also diversity is valued?

Statistics on problems

about 40 %
The monthly income of "developmentally disabled" in "Employment System for Persons with Disabilities (Japan)" is 40% of the average amount, making it difficult for them to live independently. *

about 70 %
Unemployed / Significantly underestimated *

A survey of people with ASD

about 66 %
Suicidal ideation *

A survey of people with Asperger's Syndrome *

about 9.6 times
Suicide rate *

A survey of people with Asperger's Syndrome

about 77 %
Who Have Been Bullied *

A study in Canada found that people on the autism spectrum, especially high-functioning people who "do not need special support," have been bullied. Another study found that autism spectrum disorder and ADHD are much more strongly associated with bullying victimization than other disorders. *

Cases not eligible for support, discrimination, sexual assault...

Then, we launched our NPO because

This is how DiODEN started. And...

DiODEN is Japan's first NPO promoting "neurodiversity"

What is neurodiversity?

Each of us has different Neurotypes (way of cognition and thinking). However, in contrast to such diversity, in modern times

The concept, Neurodiversity was born from the awareness of these problems
Neurotypes, like sexual orientation and race, are an imprortant part of human natural diversity. And people with any Neurotype should be treated with fair respect in society.

This is a new way of thinking (paradigm) and a civil rights movement that began in the 1990s with people with Asperger's syndrome. This way of thinking is based on the idea that “difficulties in life lie in society.” (Social model)

Philosophy of DiODEN

We aim to create a society in which people with minor neurological characteristics such as Autistics, ADHD, gifted including 2E can play an active role in their own way, have confidence, and do not have to suffer any more. So we promote neurodiversity to create "a society without disability" In the society,

autistics, ADHDer, gifted, and other minorities are not discriminated structurally or directly in society

We think It should also benefit society (For more information, see 6 Proposals for a Society without Disability (Japanese)


Our goal is to cultivate an environment, culture, and system that recognizes and respects the diverse neurotypes present in each of us. We strive to create a society where individuals, each with their unique neurotypes, can maximize their strengths and support one another in areas of challenge. We believe that we can also build a society capable of adapting and sparking innovation in our ever-changing world by valuing and incorporating our neurodiverse perspectives

And we think that if a society is creating values by celebrating neurodiversity, neurominorities can easily aquire appropriate wages, suitable environments, education, work styles, and job


A theme for all of us

1 in 10 is a neurodivergent!?

According to a survey by the Ministry of Education, Culture, Sports, Science and Technology in Japan, 9.8% of children in the regular class (not the special needs class) are likely to have a "developmental disorder" at the time of the first grade of elementary school. * . And according to a survey in the United States, 11% of children are diagnosed with ADHD. * .

In addition, the tendency of neurominority such as Autistic and ADHD is distributed in a gradation in human beings, and although there are differences in the degree of gradation and the degree of "difficulty in living", everyone has such tendency. Therefore, even if you don't have diagnosed, you may have experienced some difficulties.

There is no "average brain"

No one should be "average in every aspect" of their various neurological indicators. And to begin with, we all have different brains. DiOEDN believes that we are all “participants” in neurodiversity.


Neurodiversity pattern project
When it comes to the practice of neurodiversity, you may think that it is difficult to change curreent environments unless you are the leader of an organization such as a university or a company, who has the authority to change the environment. On the other hand, some neurodivergents is lively and making use of their strengths.
In this project, we will examine what they are doing, the surrounding environment, and the practice by people around them. So, We aim to support the practice of neurodiversity by pattern language, which can extracte what are common to lively things and utilize them.

Japan's first specialized media for neurodiversity
In Japan, there has been little information on neurodiversity, leading to misunderstandings, exclusive use of neurodiversity by people who can understand English such as government and big companies, or it is not understood at all. So we launched a Japanese blog, Neurodiversity News to share information with more neuro-minorities
An online community that you can join anytime, anywhere
A neurodiversity Discord community you can participate regardless of whether you have a diagnosis. The main purpose is to improve the QOL of members through information sharing and socializing

A hub of information on "developmental disorders" where everyone can share knowledge
A wiki site to share useful information on neurodiversity with everyone click here (Japanese)
  • Official X (Twitter) account (Japanese)
  • Official YouTube account (Japanese)
  • Nihonbashi Neurodiversity Project (Japanese):
    In order to realize a "society without disability" where neurodiversity is respected, it seems very important to implement the concept of neurodiversity in the workplace so that more neurominority can become economically independent. Therefore, DiODEN supports the Nihonbashi Neurodiversity Project and will explore the possibilities by collaborating with other companies and organizations.
  • We are planning to start a social start-up for neuro-minorities to be employed in suitable environments with fair wages

Let's create
"A society without disabilities"

In order to realize a society in which current and future neurominority will no longer suffer from the difficulties, we would like to co-create a Neurodiversity-friendly society
