Key Takeaways
- The four Japanese memory supplements we compare use different routes: a probiotic strain, bacopa plus hop bitter acids, omega fatty acids with carotenoids, and ginkgo.
- All four are notified in Japan as Foods with Function Claims, filed by the maker with the Consumer Affairs Agency; the government does not review these claims.
- Morinaga Memory's strain was tested at the product's own 20 billion CFU daily amount: total RBANS scores rose 11.3 points more than placebo over 16 weeks.
- Suntory's five-ingredient combination did not change memory overall in two trials, but helped a subgroup of older adults who already showed cognitive decline.
- Ginkgo did not reduce dementia in a 3,069-person trial over a median 6.1 years, and a meta-analysis found no memory effect in healthy people.
- Check labels: Morinaga contains milk, Omega Aid PLUS contains fish oil and gelatin, and ORIHIRO says to avoid ginkgo with blood thinners or diabetes drugs.
Search for Japanese memory supplements and you will find wasabi studies, shopping lists and pages that rank brands without saying what is inside them. If you are trying to choose one for yourself or for a parent, the useful questions are simpler: what does each product actually contain per day, what research sits behind that exact ingredient, and who is it designed for?
This guide compares the four Japanese memory supplements we carry, side by side: Morinaga Memory, FANCL Brains, Suntory Omega Aid PLUS and ORIHIRO Ginkgo Biloba. Each takes a different route to the same goal. We list the daily amounts from the makers' own Japanese pages, explain what Japan's "Food with Function Claims" label does and does not mean, and summarize the human trials, including the ones that found no effect.

What Makes a Memory Supplement "Japanese"?
Many Japanese memory supplements, including all four here, are Foods with Function Claims. The maker files its safety and efficacy evidence with Japan's Consumer Affairs Agency before the product goes on the market and may then print a specific claim, such as "helps maintain memory". Unlike FOSHU products, these claims are not reviewed by the government[17].
That distinction matters when you compare Japanese brain supplements. A Food with Function Claims label tells you three useful things: the exact functional ingredient and its daily amount, the precise wording of the claim, and a notification number you can look up, because the filed evidence is public on the agency's website[17]. It does not tell you that an independent regulator judged the evidence strong.
The claims themselves are narrow and carefully worded. ORIHIRO's ginkgo, for example, is notified for maintaining memory, defined as "the ability to recall what you saw or heard a little earlier"[13]. These are claims about maintaining everyday function in people without a disease. Morinaga's and Suntory's labels say so explicitly, and ORIHIRO's label says the product is not intended for any disease-related purpose. If you want a broader primer on reading Japanese labels, see our guide to what to know before buying Japanese supplements.
How Do the Four Japanese Memory Supplements Compare?
They use four different approaches: a probiotic strain (Morinaga), two botanical compounds (FANCL), omega fatty acids with two carotenoids (Suntory), and standardized ginkgo leaf extract (ORIHIRO). All four are notified as Foods with Function Claims for maintaining memory, and each pouch or bottle covers about 30 days.
| Product | Functional ingredients (per day) | Daily serving | FFC notification | Notified claim (summary) | Allergen notes |
|---|---|---|---|---|---|
| Morinaga Memory | Bifidobacterium breve MCC1274, 20 billion CFU | 2 capsules | K527 | Maintains memory and spatial recognition | Milk[1] |
| FANCL Brains | Bacopa saponins 15 mg; matured hop bitter acids 35 mg | 4 tablets | G425 | Memory (bacopa); attention and temporary anxiety (hop acids) | None of Japan's 28 listed allergens[5] |
| Suntory Omega Aid PLUS | DHA 300 mg; EPA 100 mg; ARA 120 mg; lutein 10 mg; zeaxanthin 2 mg | 6 softgels | Notified (number not shown on maker page) | Memory (all five); attention and positive mood (DHA, EPA, ARA) | Gelatin; fish oil[9] |
| ORIHIRO Ginkgo Biloba | Ginkgo flavonoid glycosides 28.8 mg; terpene lactones 7.2 mg | 4 tablets | B575 | Maintains memory (recalling recent information) | None of Japan's 28 listed allergens[13] |
Two details stand out. First, only Morinaga relies on a single living ingredient, while Suntory's formula has five functional components. Second, the claims differ in scope: FANCL and Suntory also claim attention, and FANCL adds relief of everyday, temporary anxiety[5][9].
What Is the Evidence Behind Each One?
It varies more than the labels suggest. Morinaga's strain was tested in randomized trials at the product's own daily amount. FANCL and Suntory point to studies of their ingredients or ingredient combination rather than the finished product. Ginkgo has been tested at a much larger scale, and those trials were largely negative[2][5][9][14][15].
| Product | Key human study | Participants (n) | Duration (weeks) | Main result | Tested as |
|---|---|---|---|---|---|
| Morinaga Memory | RCT, suspected MCI[2] | 80 | 16 | Total RBANS score +11.3 points vs placebo | Same strain, same 20 billion CFU daily amount |
| FANCL Brains | RCT, matured hop bitter acids[6] | 100 | 12 | Better divided-attention (SDMT) score vs placebo | Single ingredient (35 mg/day)[5] |
| Suntory Omega Aid PLUS | Two RCTs, combined analysis[10] | Older adults with memory complaints | 12 and 24 | No overall memory effect; benefit in a subgroup with cognitive decline | Five-component combination, not the finished product[9] |
| ORIHIRO Ginkgo | GEM trial (US)[14] | 3,069 | Median 6.1 years | No reduction in dementia vs placebo | A different standardized ginkgo extract, 120 mg twice daily |
One pattern runs through the Japanese studies: each was funded or co-authored by the company behind the ingredient. That is normal for proprietary ingredients, but it means independent replication is still missing. For background on how these ingredients compare with Western options, our guide to memory support supplements goes ingredient by ingredient.
Morinaga Memory: Moderate Evidence
Morinaga's strain, B. breve MCC1274, has three randomized, placebo-controlled trials in older adults in Japan. In the strongest, 80 people with suspected mild cognitive impairment took 20 billion CFU daily for 16 weeks, and their total score on the RBANS, a battery of memory and thinking tests, improved by 11.3 points more than placebo[2]. A 24-week trial found improvements on some subscales only[3], and a 12-week trial in people with memory complaints found no overall difference from placebo[4]. Morinaga researchers are authors on all three. We cover each trial in detail in our full Morinaga Memory review.
FANCL Brains: Emerging Evidence, Ingredient by Ingredient
FANCL Brains pairs two ingredients, and FANCL's own page cites a separate study for each. For matured hop bitter acids, bitter compounds from aged hops studied by Kirin researchers, a 12-week trial in 100 adults aged 45 to 69 who perceived some decline in their thinking found a better score on a divided-attention test than placebo; memory recall improved only in a subgroup[6]. FANCL states that trial used 35 mg a day, the same amount as in four tablets[5].
For bacopa, a traditional Ayurvedic herb, FANCL cites a 12-week trial in people with age-associated memory impairment, which found improvements in mental control, logical memory and paired-word learning[7]. FANCL describes that trial as enrolling adults aged 55 and over and providing 12.5 mg of bacopa saponins a day, slightly less than the 15 mg in Brains[5]. More broadly, a meta-analysis of nine bacopa trials found faster performance on attention tasks, with the authors calling for larger head-to-head studies[8]. What we could not find is a published trial of the two ingredients combined in one tablet.
Suntory Omega Aid PLUS: Emerging Evidence, With a Caveat
Suntory tested its five-component combination in two randomized trials of healthy older Japanese adults with memory complaints. Overall, the supplement did not significantly change memory scores. In a combined analysis of the participants who already showed some cognitive decline, memory improved compared with placebo[10]. Suntory reports a mean difference of 5.4 on its memory score for that subgroup (95% CI 1.5 to 9.3), and notes that the data come from the ingredient combination rather than the finished product[9]. An earlier 4-week trial of the same DHA, EPA and ARA amounts in Japanese men aged 55 to 64 found that a brain-wave timing measure linked to attention (P300 latency) stayed stable on the supplement but slowed on placebo; the analysis covered 69 of 113 participants[11]. Suntory researchers led both studies.
For context, a Cochrane review of omega-3 supplements in cognitively healthy people aged 60 and over found no benefit on cognitive function in trials lasting six months or longer[12]. Those trials tested omega-3s rather than Suntory's exact combination, so they do not test its formula directly, but they are a reason to keep expectations modest.
ORIHIRO Ginkgo Biloba: Limited Evidence for Healthy Memory
Ginkgo has been tested at large scale, and the results are sobering. In the Ginkgo Evaluation of Memory trial, 3,069 adults aged 75 and older took 120 mg of ginkgo extract twice a day or a placebo for a median of 6.1 years, and ginkgo did not reduce the rate of dementia[14]. A meta-analysis of 13 trials in healthy people found no measurable effect on memory[15], and the U.S. National Center for Complementary and Integrative Health says ginkgo has not been shown to prevent or slow dementia[16].
ORIHIRO's product is notified in Japan for a narrower goal, maintaining everyday recall, and it lists its two standardized compound groups clearly. A small but telling quality detail: ORIHIRO says its extract has ginkgolic acid removed and confirms the level at 5 ppm or less[13].
The milk-free option

Which Japanese Memory Supplement Suits You?
Choose Morinaga Memory if you want a single ingredient tested at the product's own dose and have no milk allergy. Choose FANCL Brains if you need a milk-free tablet or care about attention as well as memory. Choose Omega Aid PLUS if you eat little fish. Choose ginkgo only with realistic expectations.
| If you… | Consider | Why |
|---|---|---|
| Want the most product-specific trials | Morinaga Memory | Trials used the same strain and daily amount[2][3] |
| Have a milk allergy | FANCL Brains or ORIHIRO Ginkgo | Neither contains Japan's 28 listed allergens[5][13] |
| Notice lapses in focus as much as memory | FANCL Brains or Omega Aid PLUS | Both include an attention claim[5][9] |
| Rarely eat oily fish | Omega Aid PLUS | Supplies DHA, EPA and ARA[9] |
| Have a fish allergy or avoid gelatin | Not Omega Aid PLUS | Made with fish oil and gelatin[9] |
| Take blood thinners or diabetes medication | Ask your doctor first | ORIHIRO's label says to avoid its ginkgo with these drugs; Omega Aid PLUS asks you to consult a doctor or pharmacist[9][13] |
A note on expectations: the positive trials for Morinaga and Suntory found their clearest effects in people who already showed some decline, not in people with sharp memories[2][10]. If you are buying for an older parent, our guide to memory supplements for seniors covers what to discuss with their doctor. If your main complaint is feeling foggy rather than forgetful, our brain fog supplements guide may be a better starting point.
Are Japanese Memory Supplements Safe?
Each product carries its own label cautions, so the safest choice depends on your allergies and medications. Morinaga contains milk. Omega Aid PLUS contains fish oil and gelatin and asks people on blood thinners, diabetes or blood-pressure drugs to consult a doctor. ORIHIRO's label says to avoid ginkgo with antiplatelet, anticoagulant, diabetes or anticonvulsant drugs[1][9][13].
| Product | Main label cautions | Other safety notes |
|---|---|---|
| Morinaga Memory | Contains milk components[1] | No adverse events in the 16-week trial[2]; probiotics carry more risk for people with severe illness or a weakened immune system[19] |
| FANCL Brains | Not for pregnancy, breastfeeding or children[5] | Check with your doctor if you take prescription medication |
| Suntory Omega Aid PLUS | Gelatin; consult a doctor or pharmacist if prescribed anticoagulants, blood-glucose-lowering or blood-pressure drugs[9] | Omega-3 side effects are mainly mild digestive symptoms[12] |
| ORIHIRO Ginkgo | Avoid with antiplatelet, anticoagulant, blood-glucose-lowering or anticonvulsant drugs[13] | Common side effects are dizziness, digestive upset and headache; may raise bleeding risk with warfarin; may be unsafe in pregnancy[16] |
Suntory's label, for example, also states that the product was not developed for people with an illness, minors, or people who are pregnant, planning a pregnancy or breastfeeding[9]. Stay within the daily amount on each label. If you are considering two of these together, for example ginkgo and Omega Aid PLUS, both carry blood-thinner cautions, so talk to your doctor or pharmacist first. None of these products replaces medical assessment if memory problems are affecting daily life.
What About Wasabi and Other Japanese Brain Ingredients?
In our search results, wasabi came up more than any other ingredient. In a 12-week randomized trial of 72 adults aged 60 and over, a wasabi supplement containing the compound 6-MSITC improved working and episodic memory compared with placebo, though not other cognitive skills. The study was funded by a wasabi supplement maker[18].
It is a genuinely interesting result, but it is one trial, and we do not currently carry a wasabi supplement. The same caution applies to other Japanese ingredients you may see promoted for the brain: look for the exact compound, the daily amount and a human trial before choosing. The four products above meet the first two tests on their labels, and the evidence section shows how far each meets the third.
Our Recommendations
Morinaga Memory Bifidobacterium: The Most Product-Specific Evidence
Why We Selected This: Morinaga Memory stands out because its single ingredient, B. breve MCC1274, was tested in randomized trials at the same 20 billion CFU daily amount the capsules provide. From Morinaga Milk Industry, whose researchers co-authored the trials of this strain, it is notified in Japan under number K527. We chose it for customers who want a simple two-capsule routine backed by trials of the exact strain inside.
Plan on about four months to match the clearest trial, and skip it if you have a milk allergy.

FANCL Brains: Memory and Attention, Milk-Free
Why We Selected This: FANCL Brains stands out because it combines two named ingredients with separate human studies, one for memory and one for attention, in a tablet that contains none of the 28 allergens covered by Japanese labeling rules. From FANCL, working with Kirin's hop research, it is notified under number G425. We chose it for customers who cannot take milk or who notice lapses in focus as much as in memory.
Suntory Omega Aid PLUS: The Omega Fatty Acid Route
Why We Selected This: Omega Aid PLUS stands out because it pairs DHA and EPA with arachidonic acid, plus lutein and zeaxanthin, a combination Suntory has studied in its own randomized trials. From Suntory Wellness, which funded and co-authored the trials of this combination, it is made in Japan. We chose it for customers who eat little oily fish and want a brain-focused omega formula rather than a standard fish oil.
ORIHIRO Ginkgo Biloba: A Simple, Transparent Ginkgo
Why We Selected This: ORIHIRO Ginkgo stands out for its transparency: it lists both standardized compound groups per daily serving and states that ginkgolic acid is removed to 5 ppm or less. From ORIHIRO, a Japanese health food manufacturer, it is notified under number B575. We chose it for customers who already prefer ginkgo and want a clearly labeled version, with realistic expectations about the evidence.
Product Comparison
| Product | Brand | Key Ingredient (per day) | Additional Ingredients | Best For |
|---|---|---|---|---|
| Morinaga Memory Bifidobacterium | Morinaga Milk Industry | 20 billion CFU B. breve MCC1274 | None active | Product-specific trials; no milk allergy |
| FANCL Brains | FANCL | 15 mg bacopa saponins | 35 mg matured hop bitter acids | Milk-free; memory plus attention |
| Suntory Omega Aid PLUS | Suntory | 300 mg DHA | 100 mg EPA, 120 mg ARA, 10 mg lutein, 2 mg zeaxanthin | Low fish intake; no fish allergy |
| ORIHIRO Ginkgo Biloba | ORIHIRO | 28.8 mg ginkgo flavonoid glycosides | 7.2 mg terpene lactones | Existing ginkgo users; not on blood thinners |
Conclusion
Japanese memory supplements are not one category but four different bets. Morinaga Memory has the most product-specific evidence, with one clearly positive trial, one mixed and one with no overall difference from placebo. FANCL Brains and Suntory Omega Aid PLUS rest on studies of their ingredients, with encouraging but early results, mostly in people who already notice some decline. Ginkgo has been tested at large scale, with little support for memory in healthy adults.
Whichever you choose, give it at least the 12 to 24 weeks most of these trials ran, check the allergen and medication notes above, and think of it as one part of a routine that also includes sleep, movement and social activity. Every Japanese study here was funded or co-authored by the company behind the ingredient, so read the claims as promising rather than settled.
