That's a great first step! Japan is indeed an amazing country and their healthcare system differs from many others, but we can still use the same general suggestions as any other country.

Similar to the previous response, you can start by contacting your local healthcare providers or clinics to inquire about gender specialist referrals. You can also reach out to local LGBTQ+ organizations or groups which often provide community support, resources and recommendation for individuals in need of gender specialist. 

These organizations and institutions are more likely to have connections to other resources and specialists in Japan. They may also provide additional context and information on supporting your brother through his gender expression journey.

Do you require any other clarification or have additional questions on resources and support systems available in Japan specifically?
