Despite growing awareness worldwide, finding an <strong>English-speaking TRT clinic in Tokyo<\/strong> remains extremely difficult. Only a handful of physicians in the city offer testosterone therapy with full English consultation.<\/p>\n\n\n\n<p class=\"has-small-font-size last-updated wp-block-paragraph\"><em>Last updated: March 2026. Content supervised by medical professionals at Tokyo Hub Clinic.<\/em><\/p>\n\n\n\n\n\n<p class=\"wp-block-paragraph\">At <strong>Tokyo Hub Clinic<\/strong>, Dr. Ichiro Kamoshita, M.D., Ph.D., provides comprehensive testosterone evaluation and treatment for international patients and expats. Located inside <strong>Hotel New Otani Garden Court, 2F<\/strong> (Chiyoda-ku, Kioicho 4-1), our clinic offers a private, comfortable environment for this sensitive treatment.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Is Testosterone Replacement Therapy?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">TRT is a medically supervised treatment that restores testosterone to healthy levels in men whose bodies no longer produce sufficient amounts. Testosterone is the primary male sex hormone and plays crucial roles in:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Maintaining <strong>muscle mass and bone density<\/strong><\/li>\n<li>Regulating <strong>mood, energy, and cognitive function<\/strong><\/li>\n<li>Supporting <strong>sexual desire and erectile function<\/strong><\/li>\n<li>Influencing <strong>fat distribution and metabolism<\/strong><\/li>\n<li>Contributing to <strong>red blood cell production<\/strong><\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">When testosterone drops below normal ranges, men may experience a constellation of symptoms that significantly impact quality of life. TRT aims to restore hormonal balance and alleviate these symptoms under careful medical supervision.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Symptoms of Low Testosterone<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Low testosterone (hypogonadism) can manifest in numerous ways. If you recognize several of the following symptoms, a blood test measuring your testosterone levels is an important first step:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Chronic fatigue<\/strong> and lack of energy despite adequate sleep<\/li>\n<li><strong>Reduced libido<\/strong> \u2014 diminished interest in sexual activity<\/li>\n<li><strong>Erectile dysfunction<\/strong> \u2014 difficulty achieving or sustaining erections<\/li>\n<li><strong>Mood disturbances<\/strong> \u2014 depression, irritability, or anxiety<\/li>\n<li><strong>Cognitive decline<\/strong> \u2014 poor concentration, memory issues, brain fog<\/li>\n<li><strong>Decreased muscle strength<\/strong> and increased body fat<\/li>\n<li><strong>Loss of body hair<\/strong> and changes in skin texture<\/li>\n<li><strong>Sleep problems<\/strong> \u2014 insomnia or excessive sleepiness<\/li>\n<li><strong>Decreased bone density<\/strong> \u2014 increased fracture risk<\/li>\n<li><strong>Night sweats<\/strong> or unexplained temperature changes<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">TRT at Tokyo Hub Clinic<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Dr. Kamoshita follows evidence-based protocols aligned with both <strong>Japanese Urological Association<\/strong> and international guidelines. Our approach combines rigorous diagnosis with individualized treatment planning.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Who Qualifies for TRT?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">TRT is not appropriate for every patient. Candidacy is determined through:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Clinical symptoms:<\/strong> Presence of hypogonadal symptoms as described above<\/li>\n<li><strong>Blood testosterone levels:<\/strong> Total testosterone and free testosterone measurements taken in the morning (when levels peak). In Japan, a total testosterone level below approximately <strong>11.8 nmol\/L (340 ng\/dL)<\/strong> or free testosterone below <strong>8.5 pg\/mL<\/strong> is generally considered low.<\/li>\n<li><strong>Exclusion of contraindications:<\/strong> Including prostate cancer, severe sleep apnea, uncontrolled heart failure, or elevated red blood cell counts<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Types of TRT Available in Japan<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The TRT landscape in Japan differs from Western countries in several important ways:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Intramuscular Injection (Primary Method):<\/strong> Testosterone enanthate (Enarmon Depot) is the most widely used form of TRT in Japan. Injections are administered at the clinic every 2\u20134 weeks. This is the most established and commonly prescribed option, covered by <strong>National Health Insurance (NHI)<\/strong> when medically indicated.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Topical Testosterone Gel:<\/strong> Testosterone gel formulations are available in Japan, though they are less commonly prescribed than injections. Gel is applied daily and provides more stable hormone levels, but may not be covered by insurance in all cases.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Key Differences from Overseas:<\/strong> Unlike the United States and some European countries, testosterone pellet implants and certain long-acting injectables (such as testosterone undecanoate \/ Nebido) are <strong>not approved or widely available in Japan<\/strong>. If you were on a different TRT protocol abroad, Dr. Kamoshita can help you transition to an appropriate regimen available here.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The Treatment Process<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Step 1: Book a Consultation<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Call <strong>03-6261-7070<\/strong> or visit our <a href=\"https:\/\/travelershospital.com\/patient-form\/?utm_source=hub-clinic.tokyo&#038;utm_medium=partner_seo&#038;utm_campaign=testosterone-therapy&#038;th_ref=cta_bottom\">appointment page<\/a> to schedule. Our clinic is reservation-only, ensuring dedicated time for your evaluation. Mention that you are interested in hormone evaluation or TRT when booking.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 2: Comprehensive Blood Work<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">At your first visit, we draw blood to measure total testosterone, free testosterone, LH, FSH, prolactin, PSA (prostate-specific antigen), complete blood count, liver function, and lipid profile. Blood is ideally drawn in the morning when testosterone levels peak. Results are typically available within 3\u20135 business days.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 3: Diagnosis and Treatment Planning<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Dr. Kamoshita reviews your results with you in English, explains whether TRT is appropriate, and discusses the expected benefits, timeline, and potential risks. If TRT is indicated, you will agree on a treatment schedule together.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 4: Treatment Initiation<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">For injection-based TRT, your first dose is administered at the clinic. Typical dosing is <strong>125\u2013250 mg of testosterone enanthate every 2\u20134 weeks<\/strong>, adjusted based on your individual response and blood levels.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 5: Regular Monitoring<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Ongoing blood work is essential for safe TRT. We monitor testosterone levels, hematocrit (red blood cell count), PSA, liver function, and lipid levels at regular intervals \u2014 typically every <strong>3 months initially<\/strong>, then every <strong>6\u201312 months<\/strong> once stable. This ensures therapy remains safe and effective.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Side Effects and Safety<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">TRT is generally safe when properly administered and monitored. However, potential side effects include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Polycythemia<\/strong> (elevated red blood cell count) \u2014 the most common side effect, monitored through regular blood tests<\/li>\n<li><strong>Acne or oily skin<\/strong> \u2014 usually mild and manageable<\/li>\n<li><strong>Fluid retention<\/strong> \u2014 typically temporary<\/li>\n<li><strong>Sleep apnea worsening<\/strong> \u2014 in patients with pre-existing sleep apnea<\/li>\n<li><strong>Reduced sperm production<\/strong> \u2014 TRT suppresses natural sperm production; an important consideration for men planning to father children<\/li>\n<li><strong>Mood changes<\/strong> \u2014 both positive (improved mood) and occasionally negative (irritability) during dose adjustments<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Dr. Kamoshita carefully screens for contraindications before starting therapy and provides thorough monitoring throughout treatment. The goal is always the <strong>minimum effective dose<\/strong> that relieves symptoms while maintaining safety.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">For Expats and International Residents<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">If you have been receiving TRT in your home country and have relocated to Japan, you may be concerned about continuity of care. Here are the key points to know:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>You cannot import testosterone<\/strong> into Japan for personal use without prior approval from the Ministry of Health. Attempting to do so can result in confiscation at customs.<\/li>\n<li><strong>Prescriptions from overseas are not valid<\/strong> in Japan. You will need a new evaluation and prescription from a Japanese-licensed physician.<\/li>\n<li><strong>Dr. Kamoshita can review your previous medical records<\/strong> and bloodwork to facilitate a smooth transition to a Japan-approved TRT regimen.<\/li>\n<li><strong>Bring documentation<\/strong> of your previous treatment (dosage, frequency, last blood results) to your first appointment.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Our clinic is one of the <strong>very few in Tokyo<\/strong> where you can discuss TRT in English with a knowledgeable physician. There is no need for interpreters or translation services.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Insurance &amp; Pricing<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">TRT for medically diagnosed hypogonadism is covered by <strong>Japan&#8217;s National Health Insurance (NHI)<\/strong>. With insurance, your costs are typically:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>First visit (consultation + blood tests):<\/strong> Approximately \u00a510,000\u2013\u00a515,000<\/li>\n<li><strong>Follow-up visits (injection + monitoring):<\/strong> Approximately \u00a55,000\u2013\u00a58,000<\/li>\n<li><strong>Testosterone injection (NHI-covered):<\/strong> A fraction of the cost compared to self-pay clinics<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">If you do not have Japanese health insurance, self-pay rates are available. We provide detailed English-language receipts for insurance claims with your home country insurer. Visit our <a href=\"\/en\/pricing\/\">Pricing page<\/a> for more information.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Frequently Asked Questions<\/h2>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>How quickly will I notice results from TRT?<\/summary>\n<p class=\"wp-block-paragraph\">Most men begin to notice improvements in energy and mood within <strong>2\u20134 weeks<\/strong>. Sexual function improvements may take <strong>4\u20138 weeks<\/strong>. Changes in body composition (increased muscle, decreased fat) typically become noticeable after <strong>3\u20136 months<\/strong> of consistent therapy. Full effects generally develop over 6\u201312 months.<\/p>\n<\/details>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>Is TRT a lifelong commitment?<\/summary>\n<p class=\"wp-block-paragraph\">Not necessarily. Some men use TRT for a defined period and then taper off, depending on the underlying cause. However, if your body&#8217;s testosterone production has permanently declined (common with aging), long-term therapy may be recommended. Dr. Kamoshita will discuss the expected duration based on your individual situation.<\/p>\n<\/details>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>Will TRT affect my fertility?<\/summary>\n<p class=\"wp-block-paragraph\">Yes, TRT can suppress sperm production, potentially leading to temporary infertility. If you are planning to father children, this must be discussed before starting therapy. Alternative treatments such as hCG (human chorionic gonadotropin) may be considered to maintain fertility while addressing low testosterone symptoms.<\/p>\n<\/details>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>Can I bring my testosterone medication from abroad?<\/summary>\n<p class=\"wp-block-paragraph\">Importing testosterone into Japan requires advance approval from the Ministry of Health, Labour and Welfare through the Yakkan Shomei process. Without this approval, testosterone products will be confiscated at customs. We recommend starting a new prescription in Japan instead. Bring your medical records and previous blood results to facilitate a smooth transition.<\/p>\n<\/details>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>Does TRT increase the risk of prostate cancer?<\/summary>\n<p class=\"wp-block-paragraph\">Current medical evidence does not support a direct causal link between TRT and prostate cancer. However, TRT is contraindicated in men with known or suspected prostate cancer. We screen for prostate health (PSA blood test) before starting therapy and monitor regularly throughout treatment as a safety precaution.<\/p>\n<\/details>\n\n\n\n<div class=\"wp-block-buttons is-content-justification-center is-layout-flex wp-container-core-buttons-is-layout-fe48e5de wp-block-buttons-is-layout-flex\">\n\n<div class=\"wp-block-button has-custom-font-size has-large-font-size\"><a class=\"wp-block-button__link has-white-color has-text-color has-background wp-element-button\" href=\"https:\/\/travelershospital.com\/patient-form\/?utm_source=hub-clinic.tokyo&#038;utm_medium=partner_seo&#038;utm_campaign=testosterone-therapy&#038;th_ref=cta_bottom\" style=\"border-radius:8px;background-color:#2563eb\">Schedule Your TRT Consultation<\/a><\/div>\n\n<\/div>\n\n\n\n<p class=\"has-text-align-center wp-block-paragraph\">Call <strong>03-6261-7070<\/strong> \u2014 Reservation required.
