ED Treatment Cost in Tokyo: PDE5 Inhibitors, ICI Therapy, and Shockwave — A Full Breakdown
Erectile dysfunction (ED) is far more common than many men realise, yet it remains one of the most under-discussed health concerns — particularly for international patients navigating a foreign healthcare system.
Whether you are an expatriate living in Tokyo or a visitor seeking discreet, English-speaking care, understanding your treatment options and what they realistically cost is the first practical step toward finding an answer.
This article walks through the three most commonly available ED treatment pathways in Tokyo — oral PDE5 inhibitors, intracavernosal injection (ICI) therapy, and low-intensity shockwave therapy — covering how each works, expected results, and realistic cost ranges in Japan.

Understanding ED Treatment: The Three Main Pathways
ED treatment has evolved considerably over the past two decades.
Most men begin with the simplest, most accessible option and progress to alternatives only if the first-line approach is insufficient. Each pathway operates through a different physiological mechanism, which is why they are not interchangeable.
PDE5 Inhibitors: Oral Medication (First-Line)
Phosphodiesterase type 5 inhibitors — commonly known by brand names such as Viagra (sildenafil) and Cialis (tadalafil) — are the globally established first-line pharmacological treatment for ED. These medications work by inhibiting an enzyme (PDE5) that restricts blood flow to the penis, allowing the smooth muscle to relax and erections to occur in response to natural sexual stimulation.
Sildenafil is taken 30–60 minutes before sexual activity and lasts approximately four to six hours. Tadalafil offers a longer window of up to 36 hours and is also available in a low daily-dose form (2.5–5 mg) for men who prefer spontaneity. Neither medication produces an erection without arousal — a critical distinction from ICI therapy.
Clinical evidence for PDE5 inhibitors is robust. Studies suggest response rates of 60–85% in men with mild to moderate ED, with somewhat lower efficacy in men with severe vascular disease or post-radical prostatectomy status.
Intracavernosal Injection (ICI) Therapy: Second-Line
For men who do not achieve satisfactory results with oral therapy — or for whom PDE5 inhibitors are contraindicated (for example, those taking nitrate medications for heart conditions) — intracavernosal injection (ICI) therapy is a proven alternative. ICI involves injecting a vasoactive compound directly into the erectile tissue (corpus cavernosum) of the penis using a very fine needle.
The most widely used formulations are Trimix (a combination of alprostadil, papaverine, and phentolamine) and Bimix (papaverine and phentolamine). These agents directly cause smooth muscle relaxation and arterial dilation, producing an erection typically within five to fifteen minutes that is independent of arousal and lasts 30–60 minutes depending on dose.
Clinical reports indicate that ICI therapy achieves satisfactory erections in approximately 70–90% of men who have not responded to oral PDE5 inhibitors, making it one of the most effective pharmacological options available. The technique is taught to patients for self-administration at home under initial physician guidance and supervision.
Low-Intensity Shockwave Therapy (LiSWT): Regenerative Option
Low-intensity shockwave therapy applies acoustic sound waves to penile tissue, stimulating neovascularisation (formation of new blood vessels) and nerve regeneration. Unlike PDE5 inhibitors or ICI therapy, shockwave therapy aims to address an underlying vascular cause of ED rather than simply producing a temporary erection.
A typical course involves six to twelve weekly sessions, each lasting approximately fifteen to twenty minutes. Studies suggest that LiSWT improves International Index of Erectile Function (IIEF) scores significantly in men with mild to moderate vasculogenic ED, though response rates in severe cases or neurogenic ED are more modest. Effects may last twelve to twenty-four months in responders, and repeat courses are possible.
It is worth noting that shockwave therapy is not yet universally approved as a standard-of-care treatment in all countries. In Japan, it is offered at specialist clinics on a self-pay basis and should be discussed carefully with a physician to determine whether you are a suitable candidate.
Comparison: PDE5 vs ICI vs Shockwave Therapy
| Feature | PDE5 Inhibitors | ICI Therapy (Trimix/Bimix) | Shockwave Therapy (LiSWT) |
|---|---|---|---|
| Mechanism | Enzyme inhibition — enhances natural arousal response | Direct smooth muscle relaxation via injection | Acoustic wave stimulation — promotes new blood vessel growth |
| Requires arousal? | Yes | No | N/A (alters underlying physiology) |
| Onset | 30–60 min (sildenafil); 15–30 min (tadalafil) | 5–15 min | Results build over 4–8 weeks after course completion |
| Duration per use | 4–6 hrs (sildenafil); up to 36 hrs (tadalafil) | 30–60 min | Long-term (months) |
| Self-administered? | Yes (oral tablet) | Yes (after physician training) | No (clinic-based sessions) |
| Best suited for | Mild to moderate ED; first-line candidates | PDE5 non-responders; contraindications to oral therapy | Mild–moderate vasculogenic ED; desire to reduce medication dependence |
| Main risks | Flushing, headache, drug interactions (nitrates) | Priapism (prolonged erection), bruising, fibrosis with long-term use | Mild discomfort; limited long-term safety data |
| Cost level (Tokyo) | Low–moderate | Moderate | High (course-based) |
ED Treatment Cost in Tokyo: What to Expect
All ED treatments in Japan are provided on a self-pay (out-of-pocket) basis, as they fall outside the scope of the national health insurance system for most indications. Costs vary depending on the specific treatment, the clinic, and the volume or duration of care required.
PDE5 Inhibitor Costs
In Tokyo, oral sildenafil (generic) typically costs approximately ¥500–¥1,500 per tablet at a men’s health clinic, depending on dosage and quantity. Branded Viagra and Cialis command a premium, often ¥2,000–¥4,000 per dose. Tadalafil daily low-dose therapy (for those preferring a continuous regimen) may run ¥10,000–¥30,000 per month.
A mandatory initial consultation is required at any reputable clinic before prescribing — standard initial consultation fees in Tokyo typically start around ¥3,300. Ongoing prescription renewal consultations are generally less expensive.
ICI Therapy Costs
ICI therapy involves both a physician consultation and training session, plus the ongoing cost of compounded medication. An initial ICI consultation and in-clinic instruction session in Tokyo typically ranges from ¥10,000 to ¥30,000. The compounded Trimix or Bimix formulation itself — usually dispensed in a multi-dose vial — may cost ¥15,000 to ¥40,000 per supply cycle, depending on concentration and volume.
Because ICI requires careful dose titration and injection technique training, follow-up appointments are standard practice, adding to the overall cost. Men considering ICI should budget for a full initiation course rather than a single visit.
Shockwave Therapy Costs
Shockwave therapy in Tokyo is session-based and represents the highest upfront cost among the three options. A single shockwave session at a Tokyo clinic typically costs ¥20,000–¥50,000. A standard course of six sessions therefore carries a total cost in the range of ¥120,000–¥300,000, though package pricing at some clinics may offer a modest discount.
It is important to note that results from shockwave therapy are not guaranteed and individual response varies. For an accurate quote tailored to your specific situation, a consultation is strongly recommended before committing to a full course.
Dr. Karibe’s Note
Many of our international patients are surprised to find that ED consultations in Tokyo can be conducted with complete discretion and in English.
A common question I receive is whether ICI therapy is “too complicated” for self-administration — in practice, most patients find the technique straightforward after a proper training session, and the option significantly broadens the range of men we can help, particularly those who have not responded well to oral medications. At BIOTOPE CLINIC, we offer both PDE5 inhibitor prescriptions and ICI therapy (Trimix/Bimix) under physician guidance for appropriate candidates. Feel free to raise any questions during a consultation.

Who Is a Good Candidate — and Who Should Use Caution
Suitable Candidates
Most adult men experiencing persistent or recurring difficulty achieving or maintaining erections are reasonable candidates for an initial ED consultation. PDE5 inhibitors are appropriate for men with mild to moderate ED and no contraindications to vasodilatory medications. ICI therapy is particularly suitable for men with severe vascular ED, those who have undergone prostate surgery, or those for whom oral therapy has proven ineffective or inadvisable.
Shockwave therapy is generally most appropriate for men with vasculogenic (blood-flow-related) ED of mild to moderate severity who are motivated to reduce long-term medication use. Psychological or hormonal causes of ED should be identified and addressed separately, as shockwave therapy targets vascular physiology only.
Who Should Exercise Caution or Seek Specialist Guidance First
Men taking nitrate medications (commonly prescribed for angina or heart conditions) must not use PDE5 inhibitors, as the combination can cause a dangerous drop in blood pressure. ICI therapy carries a risk of priapism — a prolonged, painful erection requiring urgent medical treatment — if dose is not correctly calibrated, which is why initial titration under physician supervision is essential.
Men with bleeding disorders, penile anatomical abnormalities (such as Peyronie’s disease with significant curvature), or active penile infections should discuss these conditions with a physician before commencing any treatment. A full medical history review at consultation is not optional — it is a safety requirement.
Common Misconceptions About ED Treatment in Tokyo
Misconception 1: “I can just buy ED medication online and skip the consultation.” While generic sildenafil is widely available through internet pharmacies without a prescription, this approach bypasses the necessary screening for cardiovascular contraindications and drug interactions. A face-to-face (or video-based) consultation with a licensed physician is a safety step, not a formality, and is required at any legitimate clinic in Japan.
Misconception 2: “Shockwave therapy is a cure for all types of ED.” Shockwave therapy is best suited to vasculogenic ED — that is, ED caused primarily by insufficient blood flow. It is unlikely to meaningfully benefit men whose ED is predominantly psychological, hormonal, or neurological in origin. Clinical reports indicate response rates are notably lower outside the vasculogenic subgroup. A proper assessment before choosing any modality is essential.
Where to Get ED Treatment in Tokyo (English-Speaking)
Navigating the Japanese healthcare system as a non-Japanese speaker can be genuinely difficult, particularly for sensitive men’s health concerns where clear communication is essential.
Within our clinic group, English-speaking consultations are handled at BIOTOPE CLINIC in Shirokanedai (Minato-ku, Tokyo) by Dr. Jun Karibe. BIOTOPE CLINIC offers ED treatment including PDE5 inhibitor prescriptions (sildenafil/tadalafil) and intracavernosal injection (ICI) therapy with Trimix/Bimix under physician guidance — both available as part of the clinic’s men’s health programme. These treatments are available at BIOTOPE CLINIC in Shirokanedai; feel free to ask about them during a consultation with Dr. Karibe.
Our sister clinic, Kojimachi Dermatology & Plastic Surgery Clinic, located in Ichigaya (Chiyoda-ku), is the group’s main office and specialises in insurance-covered dermatology conducted in Japanese. English-speaking patients should direct all enquiries and bookings to BIOTOPE CLINIC. Bookings and enquiries in English: LINE or WhatsApp.
In Dr. Karibe’s clinical experience at BIOTOPE CLINIC, international patients often arrive having already self-treated with online-purchased medications for some time without a proper diagnosis or dose assessment. An initial consultation allows for a thorough review of medical history, relevant cardiovascular screening questions, and an informed discussion of which treatment pathway is most appropriate for each individual.
Frequently Asked Questions
- Q. Is ED treatment covered by Japanese national health insurance?
- In the vast majority of cases, ED treatment — including oral PDE5 inhibitors, ICI therapy, and shockwave therapy — is not covered by Japan’s national health insurance system and is provided on a self-pay basis. There are narrow exceptions (for example, sildenafil is covered when prescribed for pulmonary arterial hypertension), but for sexual dysfunction these treatments are considered outside insurance scope. All costs should be budgeted as out-of-pocket expenses.
- Q. How long before I see results from shockwave therapy?
- Most men who respond to shockwave therapy notice improvement in erectile function four to eight weeks after completing a standard course of six sessions. The improvement reflects underlying vascular regeneration, which is a gradual biological process rather than an immediate pharmacological effect. Follow-up assessment is recommended after the full course to evaluate response and discuss whether additional sessions are warranted.
- Q. Is ICI (self-injection) therapy painful?
- The injections use a very fine (27–30 gauge) needle and are administered into the side of the penile shaft, an area with relatively few pain receptors. Most men report mild discomfort rather than significant pain, particularly after the first few self-injections once technique is established. Proper training with a physician significantly reduces both discomfort and the risk of complications such as bruising or inadvertent incorrect placement.
- Q. Can I combine PDE5 inhibitors with shockwave therapy?
- Some clinical protocols allow for ongoing use of oral PDE5 inhibitors during and after a shockwave therapy course, and some research suggests this combination may improve outcomes in certain patients. However, this decision must be made on an individual basis by a physician who has reviewed your full medical history. Combining treatments without medical oversight is not advisable.
- Q. How do I know which ED treatment is right for me?
- The appropriate treatment depends on the severity and likely cause of your ED, your cardiovascular health, any medications you are currently taking, and your personal preferences. A structured consultation — including a review of medical history and relevant questions about onset, frequency, and associated symptoms — is the essential first step before any prescription or treatment is initiated.

Summary
ED treatment in Tokyo spans three well-established pathways: oral PDE5 inhibitors (sildenafil/tadalafil) as a first-line option, ICI therapy (Trimix/Bimix) for men who require a more direct pharmacological approach, and low-intensity shockwave therapy for those seeking a regenerative, longer-term vascular intervention. Each carries a different cost profile, mechanism, and appropriate patient profile.
Cost ranges in Tokyo are broadly: ¥500–¥4,000 per dose for oral PDE5 inhibitors; ¥10,000–¥30,000 for ICI initiation plus ¥15,000–¥40,000 per medication cycle; and ¥120,000–¥300,000 for a standard six-session shockwave course. All require an initial consultation, which typically starts at ¥3,300. For an accurate quote, we recommend booking a consultation.
No treatment option is appropriate for every patient, and self-medicating without physician assessment carries genuine cardiovascular and safety risks. The most important step is an informed consultation with a doctor who can assess your individual situation and speak with you in clear, accurate English.
