A Different Standard of Care

A regenerative medicine clinic, in the truest sense.

Rakan Clinic Tokyo is built around a single conviction: that the body, given the right cells and the right environment, knows how to heal itself. We do not chase trends. We pursue the small number of therapies — autologous stem cells, exosomes, and platelet-rich plasma — that the global evidence base, and our own clinical experience, have proven to work.

Our Therapies

Three pillars of cellular regeneration.

Each therapy stands on its own. Together, they address the spectrum from local joint repair to whole-body anti-inflammatory and anti-aging effects.

01 — Stem Cells

Autologous Adipose-
Derived Stem Cells

Approximately one grain of rice's worth of fat is collected with a needle — no scalpel, no incision. Cells are cultivated in our in-house CPC facility for six to eight weeks, then administered by IV drip or intra-articular injection.

Premium Program
02 — Exosomes

Bone-Marrow Derived
Exosome Therapy

Concentrated signaling vesicles derived from BM-MSC. One trillion exosomes per vial, available as single-source or as a three-vial set drawn from umbilical, bone marrow, and dental pulp tissue.

03 — PRP

SR-PRP — Super
Rich Platelet Therapy

A platelet concentration five to six times that of standard PRP, with over twenty billion platelets per injection. Delivered intra-articularly for knees, shoulders, and tendon-related conditions including tennis and golfer's elbow.

Why Rakan

Four convictions that
define our practice.

01

In-House CPC Facility

Harvest, cultivation, and administration are performed entirely within our walls — under physician supervision at every stage. No external laboratories, no logistical uncertainty.

02

Needle Harvest, No Scalpel

Adipose tissue is collected through a dedicated needle — a single grain's worth. A bandage afterwards is enough. Same-day sightseeing is entirely possible.

03

35+ Years in Orthopedics

Our orthopedic surgeon, Dr. Kei Shimizu, has spent over three decades in clinical practice. He specializes in surgery-avoidance pathways using stem cells and PRP.

04

Trilingual Patient Care

Consultations are conducted in English, Mandarin, and Japanese. Our protocols are designed for international patients — including same-day harvest itineraries for those flying in from abroad.

Cell Processing Center

Our own CPC,
inside the clinic.

Every stage — harvest, cultivation, quality control, and administration — is performed within a Cell Processing Center located inside our medical corporation in Azabudai. There is no external laboratory, no shipping, no chain of custody outside our supervision.

From Abroad

A regenerative
itinerary, in one visit.

Most international patients complete consultation and harvest in a single day. Pre-submit your blood work from your home country, and your time in Tokyo can be devoted to the clinic — and to the city.

Before Departure

Pre-flight Bloodwork

Complete the required panel — HBs, HCV, HIV, syphilis, HTLV-1, plus CBC, CMP, HbA1c, CRP, and lipid profile — at your local laboratory. Submit results as PDF.

Day 1 in Tokyo

Consultation & Harvest

Approximately two hours, in total. A physician consultation followed by needle adipose harvest under local anesthesia. A single bandage is the only aftercare.

Day 2

Return Home

You may fly out the next morning. Cells are cultivated in our CPC over six to eight weeks. Administration is scheduled on your subsequent visit — also a single-day procedure.

Treatment Records

Trusted by world champions and elite athletes.

The same protocols available to international patients are the protocols our athletes choose for performance recovery and longevity.
