A second medical opinion (セカンドオピニオン) means proactively seeking an independent assessment and recommendation from another specialist, on top of an existing diagnosis or treatment plan. This practice is widely recognized in Japan, Europe, and North America as an important expression of a patient's right to be informed and to participate in their own care.
At key decision points — a cancer diagnosis, a major surgery, or long-term conservative treatment — an independent opinion from a top Japanese specialist can offer a different diagnostic perspective, reveal treatment options that were overlooked, or simply help patients feel more confident and informed about their existing plan.
MIZUHO PHARMA offers three modes of second-opinion service — written consultation, video consultation, and an in-person visit to Japan — so patients can choose flexibly based on their condition and needs, gaining access to the valuable insight of authoritative Japanese specialists at a lower cost in both time and money.

Written consultations are typically delivered within 2–3 weeks
required for the written or video consultation options
Some complex conditions carry a real risk of misdiagnosis or missed diagnosis at home; a Japanese specialist's extensive clinical experience can offer a more precise diagnostic judgment.
Drawing on their clinical experience, a Japanese specialist will assess whether a proposed surgery, chemotherapy, or radiotherapy plan aligns with the latest international guidelines, and suggest possible improvements.
Certain treatments (such as specific targeted drugs, proton therapy, or minimally invasive surgery) are more accessible in Japan; a second opinion can help uncover treatment paths not yet discussed at home.
Through a preliminary assessment from a Japanese specialist, patients can learn — before traveling — whether a Japanese hospital is willing to accept the case, the likely treatment direction, and the expected cost range, giving them a solid basis for their decision.
Choose the option best suited to the urgency of your condition, your physical situation, and your personal needs
MIZUHO PHARMA translates and organizes the patient's medical records and submits them to a Japanese specialist, who provides a written opinion based on the materials, which we then translate and deliver to the patient.
A Japanese specialist meets with the patient online, with MIZUHO PHARMA providing simultaneous professional medical interpretation. The conversation is primarily verbal, allowing for a more flexible back-and-forth on the patient's specific questions.
The patient travels to Japan for an in-depth, face-to-face discussion with a Japanese specialist. Based on a detailed consultation, additional tests can be arranged if needed to provide more comprehensive, personalized guidance.
Patients in the following situations are especially encouraged to seek an independent specialist opinion before making a final decision
Facing an unexpected diagnosis, hearing from a second specialist before starting treatment can help confirm the accuracy of the diagnosis and reveal whether more treatment options exist.
Surgery is irreversible, so the scope, timing, and approach matter a great deal. An independent assessment from a Japanese surgical specialist can help confirm whether surgery is necessary and identify the best approach.
If you have questions about a recommended chemotherapy regimen, drug choice, or treatment intensity, an outside specialist's opinion can help confirm whether the plan aligns with the latest international clinical guidelines.
If your condition hasn't improved after a period of treatment, or you're experiencing drug resistance or recurrence, it may be time to reassess your existing plan and look for a new treatment breakthrough.
If your condition is complex, the diagnosis is uncertain, or different hospitals have given conflicting conclusions, a more authoritative specialist can help clarify what's really going on.
Before formally deciding to travel to Japan for treatment, a remote second opinion can help you understand a Japanese hospital's preliminary assessment first, confirming both the necessity and feasibility of the trip and lowering the risk in your decision.
The remote service is typically completed within 2–3 weeks; an in-person visit to Japan requires about 4–6 weeks of preparation
Contact MIZUHO PHARMA and briefly describe the patient's condition and goals. Our advisor assesses whether a second-opinion service is a good fit and recommends whether the remote or in-person option better suits your needs.
Timeframe: 1–2 business daysThe patient provides existing medical records, including imaging discs, pathology reports, test results, and a medical summary. MIZUHO PHARMA arranges for a professional medical translation team to translate the materials into Japanese and format them the way Japanese physicians expect.
Timeframe: 3–5 business daysBased on the patient's specific condition and diagnosis, we precisely match the most suitable specialist from our partner Japanese medical institutions, ensuring the opinion comes from a truly relevant authority.
Timeframe: 2–3 business daysWritten consultation: the Japanese physician reviews the records and issues a written opinion covering diagnostic assessment, evaluation of the treatment plan, and recommendations. Video consultation: the physician speaks directly with the patient online, with simultaneous interpretation provided by our team. In-person visit: the patient and physician have an in-depth, face-to-face discussion, with supplementary tests arranged if needed.
Written: approx. 5–10 business days / Video and in-person: same-dayWritten consultation: MIZUHO PHARMA translates the full opinion report into the patient's language, delivering it to the patient and family for reference and safekeeping. Video consultation: our interpreter translates line by line during the discussion; patients are encouraged to take notes along the way, and we also provide a summary of the discussion afterward for reference. Note that regardless of format, this is a one-time professional assessment — Japanese physicians generally don't provide multiple rounds of follow-up Q&A on the same case; if new test results or treatment developments arise after receiving the opinion, these can be submitted as a new round of consultation.
Timeframe: 1–3 business daysNo. Seeking a second opinion is a legitimate patient right, long accepted as standard practice within the Japanese, European, and North American medical systems. A responsible physician generally won't take offense — and will often respect a patient's active engagement in their own care. There's no obligation to inform your current doctor that you're seeking a second opinion; whether to mention it is entirely up to you.
A remote second opinion is based on the medical records the patient provides, so its accuracy largely depends on how complete and thorough those materials are. The more complete the records — especially original imaging discs — the more precise the Japanese physician's assessment will be. For patients with more complex conditions or incomplete records, we generally recommend the in-person visit option for a more reliable assessment.
The final decision always rests with the patient. When the two opinions differ, patients can: share the Japanese specialist's opinion with their current doctor and discuss the differences together; or seek a third opinion for additional reference. For a written consultation, we provide a bilingual written opinion that's easy to share directly with your doctor at home; for a video consultation, we provide a summary of the discussion for you to pass along. We recommend fully understanding the pros and cons of each option before making the choice that's best for you.
A remote second opinion typically costs approximately $1,400–$4,200 USD: the written consultation covers record translation, the physician's consultation fee, and translation of the opinion; the video consultation covers record translation, the physician's consultation fee, and simultaneous interpretation. An in-person second opinion in Japan typically costs approximately $4,200–$11,000 USD for the medical portion, plus flights, accommodation, and other costs while in Japan. (Figures are rounded USD estimates converted from the original RMB pricing.) The exact cost depends on the complexity of your condition and the hospital selected; MIZUHO PHARMA provides a detailed quote before formally engaging our services.
Absolutely. A second medical opinion doesn't commit you to any particular location for further treatment — patients can: continue treatment at home (adjusting the plan based on the Japanese specialist's recommendations); choose to travel to Japan for treatment; or complete part of the treatment in Japan (such as surgery) and the rest at home. If a patient decides to pursue treatment in Japan after receiving a second opinion, MIZUHO PHARMA can seamlessly continue with booking, visa assistance, and in-person support services.
Wherever you are in your journey, an independent opinion from an authoritative Japanese specialist could offer an important reference point for your treatment decision. Your first consultation is completely free.
