What Is Erectile Dysfunction and Why Seek Treatment?
Erectile dysfunction is defined as the persistent inability to achieve or maintain an erection sufficient for satisfactory sexual activity. It is far more common than many men realise: clinical epidemiological data suggest that ED affects approximately 30–40% of men over the age of 40, with prevalence increasing with age and the presence of certain health conditions such as diabetes, hypertension, or cardiovascular disease.
ED is rarely “just psychological.” In many cases it has a physiological basis — reduced blood flow, hormonal imbalance, nerve-related issues, or a side-effect of medication.
Addressing it with the right medical support is not a luxury; for many men it is an important aspect of overall health and quality of life.
For expatriates and international visitors in Tokyo, the challenge is not the absence of treatment options, but finding a clinic where consultations are conducted in English, privacy is genuinely prioritised, and the doctor is qualified to manage both the medical workup and treatment planning.
ED Treatment Options Available at BIOTOPE CLINIC
Under the men’s health programme at BIOTOPE CLINIC in Shirokanedai, Dr. Jun Karibe offers a structured approach to ED management. Two primary treatment pathways are available, selected based on each patient’s medical history, severity of symptoms, and personal preference.
PDE5 Inhibitors: Oral Medication (Sildenafil / Tadalafil)
The most widely prescribed first-line treatment for ED worldwide is a class of drugs called PDE5 inhibitors.
The most familiar names are sildenafil (the active ingredient in Viagra) and tadalafil (the active ingredient in Cialis). These medications work by relaxing the smooth muscle tissue in the blood vessels of the penis, allowing increased blood flow in response to sexual stimulation.
They do not produce an erection independently — sexual stimulation is still required. Clinical studies indicate that PDE5 inhibitors are effective in approximately 60–70% of men with ED across various causes, with higher response rates in men without severe vascular disease. Tadalafil is also available in a lower daily-dose formulation, which some men find more convenient for spontaneity.
At BIOTOPE CLINIC in Shirokanedai, prescriptions are issued following a medical consultation to confirm that oral therapy is appropriate for the individual patient’s cardiovascular profile and existing medications. This step is medically important — PDE5 inhibitors can interact dangerously with nitrate-based heart medications.
Intracavernosal Injection (ICI) Therapy: Trimix and Bimix
For men who do not respond adequately to oral PDE5 inhibitors — due to severe vascular ED, certain neurological conditions, or following prostate surgery — intracavernosal injection (ICI) therapy is a well-established second-line option. ICI involves injecting a small volume of a compounded vasoactive medication directly into the erectile tissue (corpus cavernosum) of the penis using a very fine needle.
The two most common formulations are Bimix (two-drug combination, typically papaverine and phentolamine) and Trimix (three-drug combination adding alprostadil). These agents cause direct smooth muscle relaxation and arterial dilation independent of stimulation, meaning erections typically occur within 5–20 minutes of injection and last 30–60 minutes depending on the dose.
Clinical reports indicate that ICI therapy achieves satisfactory erections in approximately 80–90% of men who do not respond to oral therapy, making it one of the most reliable pharmacological treatments available. At BIOTOPE CLINIC, patients who are candidates for ICI therapy receive physician-supervised training on self-administration technique before using the medication at home.
Dr. Karibe’s Note
Many of our international patients are surprised to find that ICI therapy, while it sounds intimidating at first, is something most men adapt to quickly once they have been properly trained in technique and dosing.
A common concern I hear is whether the injection itself is painful — in practice, the needle used is very fine, and discomfort is usually minimal.
The more important conversation in the first consultation is always the medical history review, because choosing the right formulation and starting dose makes a significant difference in both safety and satisfaction.
Privacy and Discretion: How the Process Works
Privacy is a legitimate and reasonable concern when seeking ED treatment. At BIOTOPE CLINIC, English enquiries are handled directly through LINE or WhatsApp by the English-speaking team, meaning no front-desk language barrier and no need to explain a sensitive medical issue in Japanese over a public phone call.
Consultations with Dr. Karibe take place in a private examination room. Medical records are held in accordance with Japanese personal information protection law (APPI). Billing descriptions on receipts or statements are kept medically discreet.
The clinic does not share patient information with third parties except as required by law. For patients who travel to Japan specifically for treatment, the team can coordinate appointment timing to fit within a visitor’s schedule.
Common Misconceptions About ED Treatment
Misconception 1: ED medication is freely available online without a prescription and is therefore safe to self-prescribe.
A significant proportion of ED medications sold through online channels without a prescription are counterfeit or improperly dosed. Beyond product quality, PDE5 inhibitors carry real contraindications — particularly with nitrate medications used for chest pain (angina). A medical consultation before starting treatment is not administrative formality; it is a safety necessity.
Misconception 2: If oral medication doesn’t work, there are no further options short of surgery.
This is a common and discouraging misunderstanding. ICI therapy, as described above, is effective in the majority of men who do not respond to PDE5 inhibitors, and it is a non-surgical outpatient treatment. Surgery (penile implants) exists as a final option for a small minority of patients; it is not the default next step after oral medication.
Cost of ED Treatment in Tokyo
At BIOTOPE CLINIC, the initial consultation fee is ¥3,300. A surgical or specialised consultation with Dr. Karibe is ¥2,200. These fees cover the clinical assessment and treatment planning discussion.
The cost of PDE5 inhibitors (sildenafil or tadalafil) in Japan varies depending on dosage, brand versus generic, and quantity prescribed. As a general guide, patients can expect to pay in the range of ¥500–¥1,500 per tablet for generic sildenafil or tadalafil at a clinic dispensary, with daily-dose tadalafil formulations typically at the lower end of that range. These medications are not covered by Japanese national health insurance when prescribed for ED.
ICI therapy compounded medications (Trimix/Bimix) are priced on a per-preparation basis and discussed in detail at consultation, as dosing is individualised. The in-office training session for self-injection technique is included in the consultation process.
Note that pre-treatment blood work, which may be recommended to assess cardiovascular and hormonal baselines, is available at the clinic. For an accurate quote based on your specific situation, we recommend booking a consultation.

Who Is a Good Candidate for ED Treatment?
Men who are generally suitable for PDE5 inhibitor therapy include those in good cardiovascular health who experience mild to moderate ED and are not taking nitrate medications. A straightforward consultation with Dr. Karibe will clarify eligibility and identify the most appropriate starting point.
ICI therapy may be considered for men with more severe ED, those who have not responded to two or more trials of oral PDE5 inhibitors at adequate doses, or those with ED related to nerve damage following prostate surgery or pelvic procedures.
Men who should approach ED treatment with particular caution — or defer to a specialist assessment — include those with recent cardiac events (heart attack or stroke within six months), uncontrolled hypertension, severe liver disease, or a history of prolonged erections (priapism). These factors do not necessarily exclude treatment, but they require careful medical evaluation before any medication is prescribed.
Where to Seek English-Speaking ED Consultation in Tokyo
Within our clinic group, English-speaking consultations are handled at BIOTOPE CLINIC in Shirokanedai (Minato-ku, Tokyo) by Dr. Jun Karibe, a board-certified plastic and reconstructive surgeon who also manages the clinic’s men’s health programme. Our sister clinic, Kojimachi Dermatology & Plastic Surgery Clinic in Ichigaya (Chiyoda-ku), serves as the group’s main office focusing on insurance-covered dermatology conducted in Japanese. Bookings and enquiries in English: LINE or WhatsApp.
In Dr. Karibe’s clinical experience at BIOTOPE CLINIC, a significant proportion of men who seek ED consultations are expatriates who have delayed treatment for months or years simply because they were uncertain whether English-language medical support was available in Tokyo. The clinic’s men’s health programme was established specifically to remove that barrier.
Frequently Asked Questions
- Q. Is my consultation completely confidential? Will anything appear on insurance documents?
- ED treatment at BIOTOPE CLINIC is provided outside the Japanese national health insurance system (self-pay), which means it does not generate insurance claim records that could appear on employer-linked health insurance summaries.
- Your medical record remains private within the clinic under Japan’s Act on the Protection of Personal Information (APPI). If discretion around billing descriptions is a specific concern, the team can address this during the booking process.
- Q. I am visiting Tokyo for only one or two weeks. Can I still receive a prescription?
- A single consultation is sufficient to assess suitability and, where appropriate, issue a prescription for oral ED medication (sildenafil or tadalafil) to take home. For ICI therapy, which requires a training session and dose titration, a slightly longer engagement is helpful, though initial assessment can still be conducted during a short visit. It is advisable to book an appointment before arriving in Tokyo to ensure availability.
- Q. I have been buying sildenafil online without a prescription. Is this safe?
- Studies examining online pharmacy supply chains have found high rates of counterfeit or sub-standard ED medications, including products containing incorrect active ingredients or dangerous contaminants. Beyond product quality, taking PDE5 inhibitors without medical screening carries real cardiovascular risk for some men. A one-time consultation to confirm that you are a safe candidate and to obtain a legitimate prescription is strongly recommended.
- Q. Are there any complementary treatments at BIOTOPE CLINIC that might support men’s health more broadly?
- BIOTOPE CLINIC also offers preventive and optimisation medicine including IV drip therapy (vitamin C, glutathione), orthomolecular (nutritional) supplementation, NMN supplementation, and gut microbiome analysis — treatments that address systemic health factors which can influence sexual function. These are available at BIOTOPE CLINIC in Shirokanedai and can be discussed with Dr. Karibe during a consultation if you have an interest in a broader wellness approach alongside ED treatment.
- Q. What if I am embarrassed to discuss this in person?
- This is a concern the clinic hears frequently. Initial enquiries via LINE or WhatsApp allow patients to ask preliminary questions in writing before committing to an in-person visit. Once in the consultation room, Dr. Karibe approaches the conversation in a clinical and non-judgmental manner — ED is a recognised medical condition, and it is treated as such throughout the process.
