Who I Help
If you have a hip or knee problem and keep running into the language barrier — unclear diagnoses, instructions you can't follow, decisions you can't fully understand — I can help. Everything from first consultation to post-op follow-up, in English.
Process
Send a message via the form with your symptoms and any imaging you have. I reply personally in English within 48 hours.
No cost to reach outWe meet in person or by video. Bring your X-rays or MRI. I review everything and explain your options clearly in English — no obligation to proceed.
30 min · in person or videoIf you decide to go ahead, I arrange surgery at an accredited Tokyo hospital. Your insurance coverage (NHI, private, or self-pay) is discussed and documented in English upfront.
Surgery fee appliesAll post-op instructions, discharge notes, and follow-up appointments are in English. For international patients, remote follow-up is available from anywhere in the world.
IncludedProcedures
Minimally invasive total hip replacement for arthritis, avascular necrosis, and hip pain. Approach and implant selection tailored to your anatomy and activity goals.
Typical hospital stay: Within 2 weeks from surgery
Read: What is THA? → Read: Revision hip & knee replacement →Full and partial knee replacement for osteoarthritis and cartilage loss. Our signature technique is kinematic alignment TKA (KA-TKA) — restoring your own anatomy rather than a population average. High tibial osteotomy (HTO) for younger, active patients who want to preserve their natural joint.
TKA stay: 2–4 weeks · UKA / PFA / HTO: Within 2 weeks

Graft selection and fixation method are optimized for stability and return to activity.

This is the classic pattern of knee osteoarthritis. Depending on which part of the knee is worn, a total or partial (unicompartmental / patellofemoral) knee replacement may be the right option.
Read: TKA, UKA & PFA — which knee replacement is right for you? →Pain that's worst on stairs and localized around the kneecap often points to isolated patellofemoral arthritis, which can sometimes be treated with a smaller, kneecap-only replacement (PFA) instead of a full knee replacement.
Read: Patellofemoral Arthroplasty (PFA) →A sudden give-way, pop, or swelling right after a pivoting or landing injury is the classic story for an ACL tear.
Read: ACL reconstruction — what to expect →Isolated inner-knee (medial) pain in an active patient under 60 is often addressed by realigning the leg (HTO) rather than replacing the joint, or with a more personalized replacement if arthritis is more advanced.
Read: High tibial osteotomy (HTO) → Read: Kinematic alignment (KA-TKA) →Deep hip or groin pain — especially with stiffness or a limp — is commonly hip arthritis or a related condition. A hip replacement may be appropriate depending on severity.
Read: What is Total Hip Arthroplasty (THA)? →Instability on the outer/back side of the knee — sometimes missed on a first exam — often points to a posterolateral corner (PLC) injury, which usually needs reconstruction rather than repair.
Read: Posterolateral corner (PLC) →A kneecap that dislocates or feels like it's about to slip out usually means the medial patellofemoral ligament (MPFL) has been injured or is deficient.
Read: MPFL reconstruction →Catching, clicking, or a pinching pain with no clear injury is often a symptomatic plica — an irritated fold of joint lining.
Read: Plica syndrome →In a middle-aged or older patient, sudden medial knee pain and swelling from an everyday movement — rather than a sports injury — is a classic pattern for a medial meniscus posterior root tear (MMPRT). It's a distinct type of meniscus injury that often needs a specific root repair rather than simple trimming, and if left untreated it can accelerate arthritis in that compartment.
Read: Medial meniscus posterior root tear (MMPRT) →New pain, instability, or swelling in a joint that was replaced years ago can point to loosening, wear, or infection of the implant. This needs a distinct evaluation from ordinary post-surgical soreness, and — if needed — a different procedure: revision surgery.

About

A board-certified orthopedic surgeon at an accredited high-volume surgical center in Tokyo, with subspecialty training in joint replacement and knee surgery.
I started offering English-language care after regularly seeing foreign patients come in after months of delay — sometimes with conditions that had progressed because they couldn't navigate the system. You shouldn't have to manage a serious health problem in a language you don't speak. I can help with that.
I personally perform 100+ hip and knee replacements each year at my hospital's high-volume surgical center — this volume is directly linked to lower complication rates and more predictable outcomes.
Surgery involves real choices — about approach, implant, timing, risk. You should make those decisions in a language you're confident in.
If you have Japanese health insurance, you pay the standard co-pay. If you have private international coverage, I'll help document your care in English for claims.
You don't need a Japanese GP to refer you first. Get in touch directly — I'll help with the paperwork if your insurance requires a referral later.
Surgical outcomes in joint replacement correlate with volume. I operate at one of Tokyo's active centers — this matters for the procedure you're considering.
Fees
Most procedures are covered under Japan's National Health Insurance (NHI). If you have NHI or employer insurance (社会保険), you pay the standard 30% co-pay — the same as any Japanese patient, with no additional charge for English consultation. For uninsured or self-pay patients, I provide a clear written estimate before any decision is made.
Surgery fees are set by the affiliated hospital and vary by procedure, implant selection, and length of stay. A detailed written estimate is provided after your consultation — before any commitment.
FAQ
Yes. If you have NHI (国民健康保険) or employer insurance (社会保険), you pay the standard 30% co-pay — the same as any patient in Japan. There's no additional charge for consulting in English.
Not to contact me. We can have a conversation first, and I'll help sort out any referral paperwork if your insurance or the hospital requires one. Just get in touch directly.
Any imaging you have (X-rays or MRI — CD, USB, or digital file is fine), a note on your symptoms and history, and your insurance card. English medical records from abroad are absolutely fine.
For total knee replacement (TKA): typically 2–4 weeks. For hip replacement (THA) and partial knee (UKA/PFA): within 2 weeks. For ACL, PCL, meniscus, and PLC surgery: within 2 weeks. The exact timeline depends on your recovery.
Yes. For patients traveling to Tokyo for surgery, I offer pre-operative video consultation, a written cost estimate, surgery at an accredited facility, and structured remote follow-up after you return home — all in English.
The hospital's general staff may have limited English. I coordinate key communications on your behalf — discharge instructions, nursing handover, rehabilitation guidance — so you're not left to manage it alone.
