Most US cash-pay patients save $1,000–$4,000+ per trip depending on dose and length.

Mounjaro in Japan (sold as Mounjaro Ateos) is manufactured by Eli Lilly with identical tirzepatide formulation. All standard doses available: 2.5mg, 5mg, 7.5mg, 10mg, 12.5mg, 15mg. The pen design differs slightly; the medication is the same.
Under FDA personal-use enforcement discretion (Regulatory Procedures Manual Chapter 9-2), US patients may bring up to a 90-day personal supply of an FDA-approved drug back into the United States with appropriate prescription documentation. CBP officers handle this routinely.
Japan’s Ministry of Health sets official wholesale prices for pharmaceuticals. Even at private clinics, Mounjaro retails for a fraction of the US cash price. The savings are not a discount, a coupon, or a generic — they reflect a fundamentally different drug pricing system.
Most US patients complete this in a single 3-4 day Tokyo trip combined with normal vacation or business.

Yes. Mounjaro is FDA-approved in the United States. Under FDA personal-use enforcement discretion, US patients may bring up to a 90-day personal supply of an FDA-approved medication back into the country with appropriate prescription documentation. We provide all required English-language documentation.
Yes. Both versions are manufactured by Eli Lilly with identical tirzepatide formulation. The Japanese pen design differs slightly (sold as Mounjaro Ateos), but the medication is chemically and pharmacologically identical to US Mounjaro.
Most US cash-pay patients save $1,500–$2,500 on a 3-month trip and $4,000+ on a 6-month supply, after including flight, hotel, and meals. If you currently pay under about $250/month with insurance, the math may not favor the trip — Part 1 of our deep-read articles walks through three real scenarios.
Yes, in most cases. The IRS allows HSA/FSA funds to cover prescription medication and consultations purchased abroad, provided you retain itemized receipts. We provide English-language itemized receipts that separate consultation and medication charges. Flight and hotel are typically not HSA-eligible.
No. Bring documentation of your current US dose (a prescription or pharmacy fill record), and our prescribing physician can typically continue you at the same dose without restarting the escalation schedule.
If the online consultation is completed before arrival, the trip can be as short as 2-3 nights. Day 1: arrive. Day 2: medication delivered to your hotel. Day 3: free for tourism or business. Day 4: fly home.
Most international hotels in Tokyo can. We work with you on hotel selection if needed. If your hotel cannot accept delivery, we arrange in-clinic pickup at our Shinjuku location — a short subway ride from any central Tokyo hotel.
Our prescribing physician reviews your current dose, confirms continuation, and prepares the prescription before you fly. Most US patients complete the consultation 2–4 weeks before their trip.
