SPF50+ is only half the label. Read PA and water resistance too.
This original BeeLife visual is based on current Bioré UV Japan product pages and Japan Cosmetic Industry Association standards. No external product image is embedded.
Bioré UV Aqua Rich Watery Essence
Kao's current Japan page shows SPF50+ / PA++++ / UV耐水性★★.
The page also describes it as super waterproof and removable with soap.
Mainly UVB protection indicator
SPF is the Japanese label used for protection against UVB-related sunburn under the standard test.
UVA protection grade
PA++++ is the highest displayed PA grade under the current Japanese system.
UV water-resistance label
Japan's current standardized water-resistance display uses one or two stars when the product meets the corresponding test.
Japanese sunscreen packages often show several protection labels at once. The important thing is that SPF, PA and UV water resistance do not mean the same thing.
SPF mainly describes protection against UVB-related sunburn. PA describes UVA protection. UV耐水性 is Japan's standardized UV water-resistance label. Read all three when they are shown.
What does SPF mean in Japan?
The Japan Cosmetic Industry Association explains SPF as the Sun Protection Factor used to express protection against UVB-related erythema, or sunburn.
JCIA also explains that products whose measured SPF is significantly higher than 50 can be labeled SPF50+.
“SPF50+” is a standardized product label. It is not a statement such as “blocks 50 times more sunlight” or a guarantee that the product will work identically regardless of how much you apply.
What does PA++++ mean?
PA stands for Protection Grade of UVA. Japan's PA system converts measured UVA protection into four consumer-facing grades.
Under the current JCIA standard, PA++++ corresponds to a measured UVAPF of 16 or more.
The plus signs are protection categories derived from measured UVA protection values.
SPF and PA measure different parts of UV protection
Mainly UVB
Useful when looking at protection against UVB-related sunburn under the standardized test method.
UVA
Japan's consumer-facing grade for UVA protection. More plus signs indicate a higher protection category.
That is why a Japanese sunscreen can show SPF50+ PA++++ together. They are not duplicate claims.
What does UV耐水性★★ mean?
Japan introduced a standardized water-resistance labeling system for UV-protection cosmetics. JCIA's current standard uses two test conditions:
UV耐水性★
Based on the standardized water-resistance test using a 40-minute water-immersion condition.
UV耐水性★★
Based on the standardized water-resistance test using an 80-minute water-immersion condition.
JCIA says water-resistance labeling should be displayed together with SPF, and if PA is shown, the three labels can appear together.
A current Japan example: Bioré UV Aqua Rich Watery Essence
Kao's current Japanese page for Bioré UV Aqua Rich Watery Essence shows:
- SPF50+
- PA++++
- UV耐水性★★
- “Super Waterproof” positioning
- soap-removable guidance
This makes it a useful real-world example of how the three Japanese labels appear together on a mainstream sunscreen.
Another current 2026 example: Bioré UV Airy UV
Kao's current 2026 Bioré UV Airy UV page likewise displays SPF50+ / PA++++ / UV耐水性★★.
The point is not that every Japanese sunscreen has those exact ratings. It is that modern Japanese packaging can communicate several separate performance characteristics in a very compact label.
What overseas buyers should compare before ordering
Exact product name
“Bioré UV” is a family, not one product. Confirm the exact Japanese item.
Current package
Use the official Japan page to check whether the listing matches the current version.
SPF / PA / water resistance
Read each label separately instead of using SPF as a shortcut for the whole product.
Ingredients + amount
Compare the exact ingredient list and net amount when evaluating Japan vs overseas versions.
Japan package vs overseas package
A product with the same brand name can be sold in different countries with different packaging, language, net amount, product registration and sometimes formula or lineup.
| Check | Why it matters |
|---|---|
| Exact product name | One brand can have multiple essence, gel, milk and cream products. |
| SPF / PA | Confirms the protection label on the exact version. |
| UV耐水性 | Shows the standardized Japanese water-resistance grade when present. |
| Ingredients | Useful for checking regional or renewed formulas. |
| Net amount | Necessary for fair price comparison. |
| Package date / renewal | Beauty products are frequently renewed, so old marketplace photos can be misleading. |
For Japanese sunscreen, compare the current official Japan page with the exact product page in your country before deciding that two listings are identical.
Can Japanese sunscreen be shipped internationally?
Sometimes — but not every sunscreen can use every international-mail route.
Japan Post specifically lists sun block with an alcohol concentration over 24% among representative examples of items that cannot be sent as international mail.
Aerosol products can also fall under dangerous-goods restrictions.
A Japanese store accepting your payment does not prove that Japan Post or another carrier can export the exact sunscreen. Check the product form and carrier restrictions before paying a proxy or forwarding service.
Do not confuse “super waterproof” with UV耐水性★★
On Japanese consumer pages, you may see marketing wording such as “Super Waterproof” alongside the standardized UV耐水性★★ label.
The clean way to read the package is:
- treat UV耐水性★ / ★★ as the standardized Japanese UV water-resistance display, and
- read additional marketing descriptions in the context of the manufacturer's own product explanation.
How to read a Japanese sunscreen listing quickly
Find SPF
Example: SPF50+.
Find PA
Example: PA++++.
Find UV耐水性
Example: ★ or ★★.
Read ingredients
Especially important when comparing regional versions or sensitive-skin needs.
Check net amount
Compare price per gram or milliliter, not only package price.
Check the carrier
Alcohol concentration, aerosol format and destination rules can change the shipping answer.
Buying Japanese sunscreen from Amazon Japan?
Amazon Japan International Shipping
Check whether the exact sunscreen listing can be delivered directly to your country.
How to Buy From Japan
If direct delivery is unavailable, compare forwarding and proxy buying — but verify the sunscreen's shipping eligibility first.
FAQ
What does PA++++ mean on Japanese sunscreen?
Under JCIA's current standard, PA++++ is the highest displayed PA grade and corresponds to a measured UVAPF of 16 or more.
Is PA++++ four times stronger than PA+?
No. The plus signs represent categories of measured UVA protection. They are not simple multiples.
What does SPF50+ mean?
SPF describes UVB-related sunburn protection under the standardized test. In Japan, products measuring significantly above SPF50 can be labeled SPF50+ under the industry standard.
What does UV耐水性★★ mean?
It is Japan's standardized UV water-resistance label for products meeting the 80-minute water-immersion test condition specified by JCIA.
Does Bioré UV Aqua Rich Watery Essence currently show PA++++?
Yes. Kao's current Japan page displays SPF50+, PA++++ and UV耐水性★★ for Aqua Rich Watery Essence.
Can I ship Japanese sunscreen overseas?
It depends on the exact product and carrier. Japan Post specifically prohibits sun block with alcohol concentration over 24% from international mail, and aerosols can also be restricted.
Bottom line
Japanese sunscreen labels are easier to understand once you stop treating “SPF50+” as the whole story.
Read the package in layers:
- SPF for UVB-related protection,
- PA for UVA protection grade,
- UV耐水性 for standardized UV water resistance,
- then check the exact product, ingredients, net amount and shipping conditions.
That approach is especially useful when comparing a Japan-market sunscreen with an overseas listing that looks almost identical.

and center: SPF and PA.
SPF relates to UVB protection, while Japan's PA system communicates UVA protection grade.
For overseas buyers, the label is also a clue to whether you are looking at the current Japanese version.
The Japan Cosmetic Industry Association maintains standards for SPF and
UVA Protection Grade (PA). PA uses plus signs, with more plus signs indicating a higher UVA protection grade
under the Japanese labeling system.
SPF and PA are not the same measurement
A product can therefore show both SPF50+ and PA++++. They communicate different parts of the sunscreen's UV protection.
What does PA++++ mean?
The PA system ranges from PA+ through PA++++. Under the current JCIA standard, PA++++ is the highest displayed PA category.
The important point for consumers is not to translate a PA grade into a made-up percentage; use it as the standardized grade shown by the manufacturer.
PA++++ does not mean “four times stronger” than PA+. It is a category based on the measured UVA protection level.
Japan also standardized UV water-resistance labeling
JCIA's current standard also covers water-resistance claims for UV-protection cosmetics. When a Japanese sunscreen makes a
water-resistance claim, check the exact wording and current package rather than assuming that every “waterproof” product follows the same test.
Why the Japanese package matters
Beauty brands can reformulate or change packaging by market and by year. When buying from Japan, compare:
- Exact Japanese product name
- SPF and PA rating
- Net amount
- Ingredient list
- Water-resistance claim
- Release / renewal information
- Japanese model or SKU where available
Can Japanese sunscreen be shipped overseas?
Many sunscreens can be shipped, but the exact formulation matters. Japan Post lists sunblock with alcohol concentration
above 24% among examples that cannot be sent as international mail. Aerosol sunscreens can also fall under dangerous-goods restrictions.
Do not assume that because a Japanese store accepts the order, the forwarding carrier can export the sunscreen.
Check the exact product form and carrier rules first.
What overseas buyers should compare
| Check | Why it matters |
|---|---|
| Japan package vs local package | Can reveal a regional or reformulated version. |
| SPF / PA | Confirms the labeled UV protection grade. |
| Ingredients | Regional formulas can differ. |
| Net amount | Helps compare price fairly. |
| Shipping form | Aerosols and high-alcohol products can face restrictions. |
| Authorized local seller | May offer easier returns and clearer local labeling. |
FAQ
What does PA++++ mean on Japanese sunscreen?
Is SPF50+ PA++++ automatically better for everyone?
Can I mail Japanese sunscreen overseas?
Bottom line
Read Japanese sunscreen as a specification sheet: SPF, PA, water-resistance claim, ingredients, amount and exact package.
That is more reliable than buying from a photo or assuming the Japan and overseas versions are identical.
