About

Meet John Ishiguro

John Ishiguro, MD — Orthopaedic Surgeon

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.

Fees

Straightforward 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.

FAQ

Common questions

Can I use my Japanese National Health Insurance?

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.

Do I need a referral from a Japanese doctor first?

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.

What should I bring to the first consultation?

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.

How long is the hospital stay after surgery?

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.

I'm traveling from abroad — can you still help?

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.

Will the hospital staff speak English too?

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.

Tarsal tunnel syndrome: nerve compression in the ankle and foot

Burning, tingling, or numbness on the sole of the foot is easy to blame on plantar fasciitis or tired feet — but it can be a pinched nerve behind the inner ankle. What the evidence shows about diagnosis and when surgery helps.

Read article →

Cervical radiculopathy: when a nerve in the neck is pinched

Pain, numbness, or weakness radiating from the neck into the shoulder, arm, or hand usually means a compressed nerve root, not just muscle strain. What the evidence shows about the Spurling test, and how a collar, physiotherapy, and surgery compare.

Cubital tunnel syndrome: when the "funny bone" nerve won't settle down

Numbness in the ring and little fingers after bending the elbow is often written off as sleeping funny — but it's the second most common nerve entrapment in the arm. How it's graded, diagnosed, and what the evidence says about splints versus surgery.

Adolescent idiopathic scoliosis: a curve that's found, not felt

Most teens with scoliosis have no pain — the curve is usually found on a school screening or by a parent noticing uneven shoulders. What the evidence shows about who progresses, and how bracing, exercise, and surgery compare.

Distal radius fracture: the broken wrist, explained

A fall onto an outstretched hand is the most common way this bone breaks — and the injury looks very different in a teenager than in an older adult with thinning bone. What the evidence shows about classification, casting versus surgery, and rehabilitation.

Morton's neuroma: the burning pain in the ball of the foot

A sharp, burning pain between the third and fourth toes that feels like walking on a pebble is often Morton's neuroma. What the evidence shows about clinical diagnostic tests, corticosteroid injection outcomes, and the trade-offs between surgical approaches.

De Quervain's tenosynovitis: the thumb-side wrist pain behind "mommy thumb"

Pain at the base of the thumb that flares with gripping or lifting a child is often De Quervain's tenosynovitis, not arthritis. What the evidence shows about splinting, corticosteroid injection response rates, and when surgical release is warranted.

A shoulder that slips or dislocates once is likely to do it again — especially in younger, active patients. What the evidence shows about immobilization versus early stabilization, and Bankart repair versus the Latarjet procedure.
