ED Treatment in Tokyo – English-Speaking Doctor
Erectile dysfunction (ED) is one of the most common men’s health concerns, yet it remains one of the most difficult to discuss — especially in a foreign language. At Tokyo Hub Clinic, Dr. Ichiro Kamoshita, M.D., Ph.D., provides confidential ED evaluation and treatment entirely in English. Our clinic inside Hotel New Otani Garden Court, 2F (Chiyoda-ku, Kioicho 4-1) offers the privacy and comfort essential for addressing this sensitive issue.

ED affects an estimated one in three men over 40 to some degree. It is not merely an inconvenience — it can signal underlying cardiovascular disease, hormonal imbalance, or psychological conditions that warrant medical attention. Seeking treatment is an act of taking care of your overall health.
Understanding Erectile Dysfunction
ED is defined as the persistent inability to achieve or maintain an erection sufficient for satisfactory sexual activity. Occasional difficulty is normal and does not necessarily indicate a medical problem. However, when it becomes a recurring pattern, professional evaluation is recommended.
ED is broadly classified into two categories:
Psychogenic (Psychological) ED
Caused by mental or emotional factors, including:
- Performance anxiety — worry about sexual performance creating a self-fulfilling cycle
- Work stress and burnout — particularly common among high-pressure expat professionals in Tokyo
- Depression and anxiety disorders — which directly affect sexual arousal pathways
- Relationship difficulties — communication issues, conflict, or emotional distance
- Cultural adjustment stress — the unique psychological burden of living abroad
Psychogenic ED is more common in younger men and often responds well to treatment when the underlying psychological cause is addressed.
Organic (Physical) ED
Caused by physical factors that impair blood flow, nerve function, or hormonal balance:
- Cardiovascular disease — atherosclerosis reduces blood flow to the penis
- Diabetes — damages blood vessels and nerves over time
- Low testosterone — often associated with andropause in men over 40
- Hypertension and its medications — some blood pressure drugs contribute to ED
- Neurological conditions — affecting nerve signals to the genitals
- Obesity and metabolic syndrome — closely linked to both ED and hormonal imbalance
- Medications — antidepressants (SSRIs), antihistamines, and certain other drugs
In practice, many men have a combination of both psychological and physical factors. This is where Dr. Kamoshita’s expertise in psychosomatic medicine — treating the connection between mind and body — provides a significant advantage over purely urological or purely psychological approaches.
Symptoms We Evaluate
- Difficulty achieving an erection even when sexually aroused
- Difficulty maintaining an erection during sexual activity
- Reduced firmness of erections compared to before
- Decreased frequency of spontaneous or morning erections
- Premature or delayed ejaculation accompanying erectile problems
- Reduced sexual desire — which may indicate a hormonal component
- Anxiety about sexual performance that leads to avoiding intimacy
- Relationship strain caused by sexual difficulties
Our Approach to ED Treatment
At Tokyo Hub Clinic, we do not simply prescribe a pill and send you on your way. Our integrated approach considers physical health, hormonal status, and psychological well-being together.
Dr. Kamoshita’s background in psychosomatic medicine is particularly relevant for ED treatment. Research consistently shows that psychological factors play a role in the majority of ED cases — even those with an organic component. Stress, anxiety, and depression can worsen physical ED and prevent medications from working optimally.
Our evaluation includes:
- Detailed medical history — including medications, lifestyle, alcohol use, and relationship context
- Physical examination — when indicated
- Blood tests — testosterone levels, blood glucose, lipid profile, thyroid function, and other relevant markers
- Psychological assessment — evaluating stress, mood, anxiety, and performance-related concerns
- Cardiovascular risk screening — since ED can be an early warning sign of heart disease
What to Expect at Your Visit
Step 1: Confidential Appointment
Call 03-6261-7070 or book through our online system. All appointments are by reservation, ensuring privacy and dedicated consultation time. You do not need to state the reason for your visit when booking — simply request a general consultation.
Step 2: Comprehensive Assessment
Dr. Kamoshita will discuss your symptoms, medical history, and concerns in a private, unhurried setting. The entire conversation takes place in English. Blood tests may be ordered during this visit.
Step 3: Diagnosis and Treatment Discussion
After reviewing all findings, Dr. Kamoshita explains the likely cause(s) of your ED and recommends a treatment plan tailored to your specific situation. You will understand exactly why certain treatments are recommended.
Step 4: Begin Treatment
Treatment may begin immediately — many ED medications can be prescribed on the same day as your consultation. For hormonal or psychological components, a coordinated plan is developed.
Step 5: Follow-Up Care
ED treatment often benefits from follow-up to assess medication effectiveness, adjust dosages, and address any ongoing psychological factors. We ensure your treatment continues to work for you.
Treatment Options
PDE5 Inhibitor Medications
These are the first-line pharmacological treatments for ED worldwide and are available in Japan:
- Sildenafil (Viagra / generic): Taken 30–60 minutes before sexual activity. Effects last approximately 4–5 hours. The most well-known ED medication.
- Tadalafil (Cialis / generic): Can be taken daily at a low dose or as needed. Effects last up to 36 hours, offering more spontaneity. Increasingly popular for its longer duration.
- Vardenafil (Levitra / generic): Similar profile to sildenafil with potentially fewer visual side effects for some patients.
Dr. Kamoshita will recommend the most appropriate option based on your health profile, lifestyle, and preferences.
Hormonal Treatment
When ED is linked to low testosterone, addressing the hormonal imbalance can significantly improve erectile function — sometimes making ED medications more effective or even unnecessary. Testosterone replacement therapy may be recommended when blood tests confirm deficiency.
Psychological and Psychosomatic Approach
For psychogenic ED, Dr. Kamoshita provides counseling that addresses performance anxiety, stress management, and the mind-body connection. This approach can be used alone or alongside medication for comprehensive treatment.
Lifestyle Modifications
Regular exercise, weight management, smoking cessation, reduced alcohol intake, and improved sleep all contribute to better erectile function. These changes also reduce cardiovascular risk, which is closely linked to ED.
For Expats and International Residents
Discussing ED is difficult enough in your native language. Trying to explain intimate sexual health concerns through a language barrier — or with an interpreter present — can be so uncomfortable that many men simply avoid seeking help.
At Tokyo Hub Clinic, this barrier does not exist. Dr. Kamoshita conducts all consultations in English, so you can describe your situation precisely and understand your treatment plan completely. No interpreters. No miscommunication.
Our location inside Hotel New Otani provides another layer of comfort. From the outside, there is nothing to indicate the nature of your visit. You could be meeting someone for lunch, visiting the hotel’s garden, or simply passing through the lobby. This level of discretion matters when the stakes feel personal.
Conveniently located near Akasaka-mitsuke Station (3-minute walk) and Nagatacho Station (5-minute walk).
Insurance & Pricing
The consultation and diagnostic workup (blood tests, evaluation) for ED are generally covered by National Health Insurance (NHI). However, ED medications (PDE5 inhibitors) are typically self-pay in Japan, as they are not covered by NHI.
- First visit (consultation + blood tests): Approximately ¥10,000–¥15,000 (NHI applicable)
- Follow-up visits: Approximately ¥5,000–¥8,000 (NHI applicable)
- ED medications: Self-pay; costs vary by medication and quantity. Generic options are available at reduced prices.
We provide clear cost information before prescribing and offer English-language receipts for international insurance claims. See our Pricing page for more details.
Frequently Asked Questions
Is ED medication safe to take?
PDE5 inhibitors are among the most extensively studied medications in the world and are generally very safe for most men. However, they are contraindicated if you take nitrate medications (for heart conditions) or have certain cardiovascular conditions. Dr. Kamoshita will review your medical history and current medications to ensure safety before prescribing.
Can I get ED medication without an in-person visit?
In Japan, ED medications require a prescription from a licensed physician. An initial in-person consultation is necessary for proper evaluation and to ensure the medication is safe for you. Follow-up prescriptions may be handled more efficiently once a treatment relationship is established.
Could my ED be caused by stress?
Absolutely. Stress is one of the most common causes of ED, particularly in men under 50. Work pressure, relationship issues, financial worries, and the challenges of living abroad can all contribute. The good news is that stress-related ED responds well to treatment. Dr. Kamoshita’s expertise in psychosomatic medicine makes him particularly equipped to address these cases.
Should I get my testosterone checked?
If your ED is accompanied by other symptoms such as fatigue, low libido, mood changes, or decreased muscle mass, a testosterone check is strongly recommended. Low testosterone is a treatable cause of ED that would be missed without blood testing. We routinely include hormone levels in our ED evaluation.
My partner and I are struggling with this. Can we come together?
Yes. Partners are welcome to join the consultation if you prefer. Sexual health concerns often affect both individuals in a relationship, and having your partner present can improve communication and mutual understanding. This is entirely your choice — you are equally welcome to come alone.
