ADHD Consultation & Assessment in Tokyo – English-Speaking Clinic

You have always known something was different about the way your brain works. Maybe you were diagnosed with ADHD as a child back home — or maybe you are only now wondering whether your lifelong struggles with focus, organization, and impulsivity have a name. If you are living in Tokyo and looking for an English-speaking doctor who understands ADHD in adults, you are in the right place. At Tokyo Hub Clinic, Dr. Ichiro Kamoshita provides comprehensive ADHD assessment and treatment for international patients — with full awareness of how Japan’s approach to ADHD differs from what you may be used to.

Understanding Adult ADHD

Attention Deficit Hyperactivity Disorder (ADHD) is a neurodevelopmental condition that affects how you regulate attention, impulses, and executive function. While often associated with childhood, ADHD persists into adulthood in approximately 60% of cases — and many people are not diagnosed until their 20s, 30s, or even later. Adult ADHD is not about being lazy or undisciplined. It is a brain-based condition with well-documented neurological underpinnings.

In adults, ADHD often looks different from the hyperactive child bouncing off the walls. Instead, you might experience persistent difficulty with organization, time management, decision-making, emotional regulation, and sustained focus — particularly on tasks that do not inherently interest you. Many adults with ADHD develop sophisticated coping mechanisms that mask the condition for years, only to find those strategies collapse under the weight of a major life change — like relocating to a foreign country.

Symptoms — Do Any of These Sound Familiar?

Adult ADHD manifests differently for everyone, but the following symptoms are common:

Chronic difficulty focusing on tasks — especially paperwork, emails, or meetings
Hyperfocus on interesting tasks while neglecting everything else
Frequent procrastination and last-minute rushing
Difficulty with time management — chronic lateness, missed deadlines
Disorganization — cluttered desk, lost items, forgotten appointments
Restlessness or inner agitation — difficulty sitting still in meetings or on trains
Impulsive decisions — spending, job changes, or saying things you regret
Emotional dysregulation — quick frustration, mood swings, or sensitivity to criticism
Difficulty following multi-step instructions — especially in a second language
A history of underperformance relative to your intelligence and effort

Living in Japan can amplify these symptoms. The language barrier adds cognitive load, Japanese workplaces demand meticulous attention to detail and process, and the social rules require a level of executive functioning that can exhaust someone with ADHD. If you have been managing fine until moving to Tokyo, the added demands of expat life may have pushed your coping capacity past its limit.

ADHD Diagnosis in Japan — What You Need to Know

If you were diagnosed with ADHD in another country, it is important to understand that Japan’s approach to ADHD has several key differences from the US, UK, Australia, or Europe. Being informed will help you navigate the system smoothly.

Adderall Is Illegal in Japan

This is the single most important fact for expats with ADHD to understand. Amphetamine-based medications — including Adderall, Dexedrine, and Vyvanse — are classified as stimulant drugs under Japan’s Stimulants Control Act and are completely prohibited. You cannot bring them into the country, possess them, or have them prescribed. There are no exceptions, and violations carry severe criminal penalties including imprisonment.

If you are currently taking Adderall or a similar amphetamine-based medication, you must discontinue it before entering Japan and work with a Japanese doctor to transition to an approved alternative.

Approved ADHD Medications in Japan

Japan does have effective ADHD medications available, though the options are more limited than in some Western countries:

Concerta (methylphenidate) — A stimulant medication similar in mechanism to Ritalin. Concerta is the primary stimulant option in Japan and is effective for many patients. However, it is tightly regulated: only physicians registered with the Concerta Prescribing System (コンサータ登録制度) can prescribe it, and patients must be registered in the system as well.
Strattera (atomoxetine) — A non-stimulant medication that works on the norepinephrine system. It takes 4–6 weeks to reach full effect but provides steady, all-day coverage without the abuse potential of stimulants. A good option for patients who prefer non-stimulant treatment or cannot tolerate methylphenidate.
Intuniv (guanfacine) — Another non-stimulant option, originally developed as a blood pressure medication. It can help with hyperactivity, impulsivity, and emotional regulation. Sometimes used in combination with Concerta or Strattera.
Vyvanse (lisdexamfetamine) — As of 2023, Vyvanse has been approved in Japan for adult ADHD. This is an amphetamine-based prodrug, but because it was specifically approved through the pharmaceutical regulatory process, it is legally available by prescription through the registered prescribing system.

The Diagnostic Process Is Different

In Japan, ADHD diagnosis for adults may involve a more structured process than what you experienced at home. Clinicians typically use standardized rating scales, a detailed developmental history (sometimes requesting childhood records), and may require multiple visits before confirming a diagnosis. If you have existing documentation from your home country — previous assessments, medication records, or letters from your treating physician — bringing these to your first appointment can significantly streamline the process.

How We Can Help — Dr. Kamoshita’s Approach

At Tokyo Hub Clinic, we take a comprehensive, patient-centered approach to ADHD assessment and treatment. Dr. Ichiro Kamoshita, M.D., Ph.D. combines his expertise in psychosomatic medicine and internal medicine to evaluate ADHD within the broader context of your mental and physical health.

Our ADHD services include:

New diagnosis evaluation — If you suspect you have ADHD but have never been formally assessed, we provide a thorough clinical evaluation including symptom history, functional impact assessment, and standardized screening tools.
Continuation of existing treatment — If you were diagnosed abroad and need to continue treatment in Japan, we can review your records and transition you to available Japanese medications with minimal disruption.
Medication management — We are registered to prescribe Concerta (methylphenidate) and other approved ADHD medications in Japan. Dr. Kamoshita will work with you to find the right medication and dosage, with regular follow-up to monitor effectiveness and side effects.
Comorbidity screening — ADHD rarely exists in isolation. We screen for commonly co-occurring conditions including anxiety, depression, insomnia, and burnout — and treat them simultaneously when present.
Psychosomatic integration — Many ADHD patients experience physical symptoms such as chronic fatigue, tension headaches, or digestive issues related to stress. Our mind-body approach addresses these holistically rather than in silos.

What to Expect — Your First Visit

Book your appointment — Use our online booking system (24/7) or call 03-6261-7070. When booking, mention that you are seeking an ADHD evaluation so we can allocate adequate time.
Bring your documentation — If you have previous ADHD assessments, medication records, or letters from your treating physician abroad, bring them to your first visit. This helps us understand your history and avoid redundant testing.
Initial consultation (45–60 minutes) — Dr. Kamoshita will conduct a detailed interview covering your symptoms, developmental history, functional impacts, and treatment goals. He may use standardized screening instruments as part of the assessment.
Diagnosis and treatment plan — If ADHD is confirmed, Dr. Kamoshita will discuss medication options, lifestyle strategies, and a follow-up schedule. If further evaluation is needed, he will explain the next steps clearly.
Ongoing management — Follow-up visits (15–20 minutes) focus on medication adjustments, symptom tracking, and addressing any new challenges. Most patients stabilize within 2–3 months.

Treatment Options for ADHD in Japan

Medication

Medication remains the most evidence-based treatment for ADHD. In Japan, the available options — Concerta, Strattera, Intuniv, and Vyvanse — are effective for the majority of patients. Finding the right medication and dosage is a process that requires patience and close communication with your doctor. Dr. Kamoshita will start conservatively and adjust based on your response, side effects, and lifestyle needs.

Behavioral Strategies and Coaching

Medication alone is often not sufficient. We work with you to develop practical strategies for managing the daily challenges of ADHD: time management systems, organizational tools, prioritization techniques, and environmental modifications. For expats, this may also include strategies for managing ADHD symptoms within the context of Japanese workplace expectations.

Treating Comorbid Conditions

If ADHD coexists with anxiety, depression, or insomnia — as it frequently does — we develop an integrated treatment plan that addresses all conditions together. Treating ADHD alone while ignoring comorbid depression, for example, often leads to incomplete improvement.

For Expats and International Residents in Japan

ADHD treatment is covered by National Health Insurance — Consultations and most medications (including Concerta and Strattera) are covered at the standard 30% co-pay.
Bring your records from home — Previous assessments, prescriptions, and letters from your doctor abroad can significantly speed up the process in Japan.
Do not bring Adderall into Japan — This cannot be stressed enough. Even with a valid foreign prescription, bringing amphetamines into Japan is a criminal offense. If you are currently on Adderall, plan your medication transition before your move.
Self-referral is fine — You do not need a referral from a GP or other doctor to book with us. Japan’s healthcare system allows direct access to specialists.
Confidentiality is guaranteed — Your diagnosis is not reported to your employer, immigration authorities, or anyone else without your explicit consent.

Frequently Asked Questions

Can I get an ADHD diagnosis in Japan if I was never diagnosed before?

Yes. We provide first-time ADHD evaluations for adults. The process involves a detailed clinical interview and standardized screening tools. While having childhood records or school reports can be helpful, they are not strictly required for an adult diagnosis. The evaluation may take one or two visits depending on the complexity of your case.

I take Adderall at home. What should I do before moving to Japan?

You must discontinue Adderall before entering Japan — it is completely illegal here regardless of your prescription status. Ideally, work with your current doctor before your move to begin transitioning to a medication available in Japan, such as Concerta (methylphenidate). Bring your complete medical records, including your current prescription details, to your first appointment with us so we can facilitate a smooth transition.

How is Concerta different from Adderall?

Concerta (methylphenidate) and Adderall (amphetamine) are both stimulant medications for ADHD but work through slightly different mechanisms. Concerta is generally considered milder with fewer side effects, though some patients find it less effective than amphetamine-based medications. Many Adderall users transition successfully to Concerta with appropriate dosage adjustment. If methylphenidate is not effective, Vyvanse (lisdexamfetamine) is now also available in Japan as an alternative.

Will my ADHD diagnosis affect my visa status?

No. A mental health diagnosis in Japan does not affect your visa, work permit, or residence status. Medical records are confidential and are not shared with immigration authorities.

How quickly can I get medication after my first visit?

For non-stimulant medications like Strattera or Intuniv, a prescription can typically be issued on the same day as your evaluation. For Concerta, the process may take slightly longer because both the doctor and patient must be registered in the national Concerta Prescribing System. Dr. Kamoshita will explain the timeline during your first appointment.
