Moving to Japan opens a world of unique health and wellness options. Japan’s health supplements are popular globally for their unique ingredients and cultural heritage. They can be found in drugstores and pharmacies and support your health effectively.
However, as a female US expat, it is important to be an informed shopper when exploring this market. Knowing what to look for helps you make safe choices. From regulatory differences to hidden interactions with medications like hormonal contraceptives, informed choices are key. Here’s how to buy wisely.
Understanding Japan’s Supplement Regulatory Framework
Japan regulates supplements differently from the US. Unlike America’s DSHEA framework, Japan historically restricted supplement companies from making explicit health claims. According to NUFFOODS Spectrum ASIA, the Japanese system divides supplements into the following categories:
- FOSHU (Foods for Specified Health Uses),
- FNFC (Foods with Nutrient Function Claims), and
- FFC (Foods with Function Claims).
FOSHU products undergo strict testing and have proven health benefits. Look for the FOSHU seal on the packaging for the highest quality assurance. These products cost more but offer greater safety guarantees. The FFC system, introduced in 2015 under former Prime Minister Abe’s economic strategy, moved Japan closer to a US-style system.
Unlike FOSHU’s rigorous approval process, FFC allows companies to make claims based on scientific literature reviews rather than requiring clinical trials for each product. The Consumer Affairs Agency (CAA) overseas registration, but doesn’t pre-approve each item individually.
Companies must now provide scientific evidence for functional claims and disclose safety information before marketing supplements. This gives you more reliable information when choosing products, but requires careful evaluation of these newly permitted claims.
This focus on evidence and functional claims is correlated with significant market growth, as product shares under the FFC category are increasing rapidly. In FY2023, the supplement sector rose by 0.3%, exceeding ¥1.05 trillion in 2023. According to experts, it comprised 23.6% of Japan’s health‑food economy.
Citing Yano Research, the Japan Times expects the industry to surpass ¥1 trillion in 2025. This steady climb proves evidence‑based claims drive more brands to invest in clinical substantiation before they hit shelves.
The Kobayashi Pharmaceutical Controversy
Last year’s events in Japan have raised concerns about supplement safety. In July 2024, Kobayashi Pharmaceutical’s president stepped down after their beni koji (red yeast rice) supplements caused serious health problems. The Guardian reveals that about 80 users died from kidney damage after taking these cholesterol-lowering supplements.
This case reminds us to pay close attention to all health products we use. Anything you consume can interact with your body, impacting your hormone levels or metabolism. This is especially relevant for women using hormonal contraceptives, like pills or shots. These contraceptives work by providing a steady dose of hormones.
Introducing other substances can disrupt hormone uptake, making consistent levels and effective contraception harder to maintain. Similarly, being informed about every product influencing your health is vital, particularly for long-term use or hormone-related products. Sometimes, the information provided about potential risks is not complete.
This need for full disclosure about health product risks is a global issue. It has led to significant concerns and legal actions in various healthcare spaces. For instance, the Depo shot lawsuit in the US addresses claims that the label warnings about possible serious side effects were insufficient.
TorHoerman Law discloses that in the US, several cases were consolidated in multidistrict litigation (MDL) in the Northern District of Florida. These events emphasize the necessity of being proactive. Always seek complete information about any health product, whether a supplement or a prescription.
Remember, knowing about industry scandals is only half the battle. Next, you’ll learn how to spot safe products at a glance.
Reading Labels
To ensure your next supplement isn’t the next headline, mastering Japanese label terms is essential. However, it can be challenging because of the language barrier. Supplement labels are often only in Japanese, so major information about ingredients, dosage, and warnings can be missed. Look for key terms like “サプリメント” (supplement), “無添加” (additive-free), and “自然” (natural).
Regardless of language, watch out for red flags like missing ingredient lists or claims that seem too good to be true. Focus on identifying the main ingredients and dosage instructions. Try using translation apps to get a general idea of the label. However, do not rely solely on translation apps for critical health details.
You can also use apps like Medicine History Book Plus and EPARK Medicine History Book App to manage your medicine and prescription history. Talk to a doctor in Japan before starting any new supplement. This is very important if you have any health conditions. It is also key if you take prescription drugs, including contraceptives.
Fortunately, Japanese doctors can advise you on potential interactions. The country boasts a local clinic system where you can easily see a doctor for advice.

Commonly Asked Questions
Are Japanese supplements regulated as strictly as medications?
No, Japanese supplements aren’t regulated as strictly as medications. While FOSHU products undergo rigorous testing, most supplements fall under less stringent categories. Japan’s regulatory system focuses more on preventing false claims than guaranteeing safety. Always research brands and look for those with voluntary third-party testing for additional peace of mind.
Can I bring my US supplements to Japan when moving?
Yes. You can bring personal-use US supplements to Japan, but only up to a two-month supply. Anything more may be confiscated at customs. Some US legal ingredients are restricted in Japan, including certain herbs and stimulants. Check Japan’s prohibited ingredient list before packing your supplement collection.
How can I verify the safety of a Japanese supplement before purchasing it?
Check Japan’s Consumer Affairs Agency (CAA) website for registered FFC or FOSHU products. Look for third-party tested products like the US Pharmacopoeial (USP) Convention Dietary Supplement Verification Program or ConsumerLab. Ask healthcare professionals for recommendations, or seek out brands known for clinical transparency.
