d'Alba and AESTURA were #1 and #2 on Rakuten's beauty chart on November 3.

Japan is one of the biggest export markets for Korean cosmetics, and Rakuten Ichiba is one of its largest online malls. We read Rakuten's daily beauty and cosmetics ranking every day. Each row is one shop's listing, so a brand can appear more than once, and a listing's place is not a brand's share.

What happened on Nov 3? Two Korean brands took the top two places.

Fact. On Nov 3, #1 on Rakuten's beauty ranking was a skincare set from d'Alba's Rakuten shop, and #2 was AESTURA's Atobarrier 365 cream from AESTURA's official shop. Across the 34 daily reads we have from Oct 2 to Nov 5, no other day had brands we can verify as Korean at both #1 and #2.

It didn't last into the next day.

Fact. On Nov 4, d'Alba's listing was #7 and AESTURA's best was #17. The top three that day were three set listings from a single shop. On Nov 5, d'Alba's best was #18 and AESTURA's #15. Observation. Both brands spent most of the previous week far lower: d'Alba's best listing ranged from #69 to #120 between Oct 28 and Nov 1, and was not in the ranking at all on Nov 2. Inference. A jump from outside the list to #1 in a day, followed by a fall, is the shape of a one-day event — a feature, a coupon window or a launch — more than a slow build. The ranking shows the day, not the cause, and we don't guess which.

For d'Alba, it is the second #1 we have recorded.

Fact. A d'Alba listing was also #1 on Oct 7, a spray-serum set we covered at the time. In our reads, d'Alba has been in Rakuten's top 10 on six days: Oct 4, 5, 7, 24, Nov 3 and Nov 4. AESTURA has been in the ranking on 31 of the 34 days, most often somewhere in the 20s; #2 on Nov 3 is its best place, ahead of #4 on Oct 4.

Observation. The two brands sit differently. AESTURA is nearly always on the list and rarely near the top. d'Alba is often far down or absent, then occasionally at the very top. Over the same week, Anua was #2 on Oct 31, and on the other days from Oct 29 to Nov 5 we could verify no Korean brand in the top 10.

The same two names lead in Korea this week.

Fact. At home, AESTURA's Atobarrier 365 Cream is #1 in Olive Young Korea's skincare tab on every daily read since Oct 13, and #1 on Olive Young's US site this week. d'Alba's tone-up sun cream became Olive Young Korea's suncare #1 on Nov 8. The products differ by market, but the brands overlap. Inference. That is worth tracking because Japan's ranking usually looks little like Korea's: on 19 of the 34 days we read, it had no Korean brand we could verify in its top 10.

Counter-argument, answered first. One day is a thin basis, and we say so. We are not calling a trend in Japan. The claim is narrower: on Nov 3, Rakuten's two top beauty listings came from Korean brands, which did not happen on any other day in five weeks of reads. If it repeats, the daily archive will show it; if it doesn't, it stays a one-day record.

How to read this

Rakuten Ichiba daily ranking, beauty and cosmetics genre, by ranking date, Oct 2–Nov 5, 2026 (34 reads). Korean = brand in our Korean-brand ledger; listings whose brand we can't verify are not counted as Korean, so Korean presence here is a floor. We show brand names, not product titles, because Rakuten titles carry coupon and price text. Listing position, not sales or brand share.
