For two weeks running, Netflix's most-watched non-English series has been a Korean hospital drama about a surgeon who does not care who runs the hospital. Doctor X: Mafia in White (닥터X: 하얀 마피아의 시대) stars Kim Ji-won as Gye Su-jeong, a freelance surgeon parachuted into a corrupt university medical center, and it is a remake of one of Japan's longest-running TV hits. Four of its twelve episodes are out. Episode 5 airs in Korea on Friday, October 23.

This guide covers the schedule in Korean and US time, who is who, how the show differs from Japan's Doctor-X, and the Korean context behind some scenes. It stays spoiler-light: nothing beyond Netflix's own episode summaries.

Key takeaways

Twelve episodes, two a week: SBS airs them Fridays and Saturdays at 9:50 p.m. Korea time from October 9 to November 14, 2026, and Netflix adds each one the same day.
It is No. 1 on Netflix's non-English TV chart for the weeks ending October 11 and October 18 (4.6 million, then 7.1 million views), and its Korean ratings climbed from 11.4% to 18.5% over four episodes.
You do not need the Japanese original: the remake keeps the genius-surgeon core but tells one darker, serialized story.

1. Why everyone is talking about it

The Netflix numbers

Netflix counts "views" as hours watched divided by runtime. The show opened at No. 1 on the global non-English TV list for the week ending October 11, 2026, with 4.6 million views and a top-10 place in 36 countries, Yonhap reported. The following week (ending October 18) it stayed at No. 1 with 7.1 million views, charted in 48 countries and topped the list in seven, including South Korea, Taiwan, Vietnam and Singapore, Yonhap reported on October 21.

The same chart had the rom-com Take Charge of My Heart at No. 2 and the 1930s spy romance 100 Days of Deception at No. 4, so Korean shows held Nos. 1, 2 and 4.

The Korean ratings

Nielsen Korea figures cited by SBS put the premiere at 11.4% nationwide, the best premiere of any 2026 miniseries by SBS's count. Every episode since has gone higher: episode 4 on October 17 averaged 18.5%, peaked at 20.8% for a single minute, and was the day's most-watched program. For scale, Soompi's round-up of that night has tvN's 100 Days of Deception celebrating a new high of 7.0%. Ratings that rise every week point to word of mouth.

2. Episode schedule and what time it drops

SBS airs each episode at 9:50 p.m. Korea Standard Time (KST), and Netflix lists each one on the Korean broadcast date. Netflix has not published an exact upload time, so treat the broadcast time as the earliest an episode can appear and check back later that day.

Episodes	Korea air dates (Fri / Sat)	SBS broadcast	US Eastern	US Pacific
1-2	Oct 9 / Oct 10	9:50 p.m. KST	Out now	Out now
3-4	Oct 16 / Oct 17	9:50 p.m. KST	Out now	Out now
5-6	Oct 23 / Oct 24	9:50 p.m. KST	8:50 a.m. EDT same day	5:50 a.m. PDT same day
7-8	Oct 30 / Oct 31	9:50 p.m. KST	8:50 a.m. EDT same day	5:50 a.m. PDT same day
9-10	Nov 6 / Nov 7	9:50 p.m. KST	7:50 a.m. EST same day	4:50 a.m. PST same day
11-12 (finale)	Nov 13 / Nov 14	9:50 p.m. KST	7:50 a.m. EST same day	4:50 a.m. PST same day

Schedule as listed by Netflix and SBS as of October 22, 2026. US clocks move back one hour on November 1, 2026, which is why the last four episodes shift earlier. In UTC the broadcast is always 12:50 p.m.

How to catch up before Friday

Find the right title. Search "Doctor X: Mafia in White". Where Netflix also carries the Japanese original, the two titles look alike.
Pick audio and subtitles. Netflix's US page lists Korean audio plus English, Spanish and Portuguese dubs. Options differ by country.
Budget the time. Episodes 1-4 run 61 to 66 minutes each, so catching up takes a little over four hours.
Add it to My List so new episodes surface on your home screen.
Mute spoilers. Viewers in Korea see each episode live on SBS, so reactions can hit social media before it reaches Netflix where you are.

3. The story and the main players, spoiler-light

Netflix's pitch: a brilliant, enigmatic surgeon arrives at a hospital run on ego and corruption. The people around her make it a noir rather than a procedural.

Gye Su-jeong (Kim Ji-won)

A genius surgeon with a buried past, nicknamed the "mad dog of the operating room," sent on contract to fill a staffing gap at Guseo University Seonam Medical Center. Netflix's episode 1 summary has her weighing in on an upcoming surgery on her first day, then jumping in when a crisis hits. It is Kim Ji-won's first lead role since Queen of Tears (2024).

The people who send her and the people who resist her

Lee Jung-eun plays Jang Hui-suk, head of the locum agency that places Su-jeong: not a blood relative, but an aunt figure who shares her past. Son Hyun-joo is Bu Seung-kwon, a director who compromised with a corrupt system to keep his hospital alive. Kim Woo-seok plays Park Tae-gyeong, a kind-hearted intern, and Lee Jin-hee a cynical but unflappable anesthesiology professor.

The "white mafia"

The title points at the Magnolia Association, a clique led by the hospital's board chairman that links senior doctors, the city medical association and the mayor. Episode 2 sets up the show's recurring question: with two pancreatic cancer patients, a wealthy chairman and a teenager, who goes first? Like the Netflix hit in our KPop Demon Hunters review, it is a crowd-pleaser built on a clear hero and clear villains.

4. Japan's Doctor-X versus the Korean remake

TV Asahi's Doctor-X: Surgeon Michiko Daimon ran seven seasons from October 2012 to December 2021, plus a 2024 film. Ryoko Yonekura's freelance surgeon became famous for one line: "I never fail" (私、失敗しないので).

	Doctor-X: Surgeon Michiko Daimon (Japan)	Doctor X: Mafia in White (Korea)
Network and years	TV Asahi, 2012-2021	SBS, October 9 to November 14, 2026
Length	7 seasons, 69 episodes + 1 special	12 episodes, Netflix calls it a limited series
Lead	Ryoko Yonekura as Michiko Daimon	Kim Ji-won as Gye Su-jeong
Who places her	A medical referral agency run by a former surgeon	A locum agency run by an aunt figure who shares her past
Shape of the story	Largely self-contained cases, with new hospital rivals each season	A season-long conflict with one corrupt network
Tone	Medical drama with comedy	Billed as medical noir with dark comedy

What carries over, and what changes

The core is the same: a contract surgeon who ignores hierarchy and wins arguments with results. The big change is structure. A long-running Japanese series can reset each week; a 12-episode Korean drama needs one villain and one secret to pay off by the finale, so Su-jeong's shared past with Hui-suk does a lot of work. Viewers are split on the lead. One MyDramaList reviewer argues the remake "toned down" Daimon's bluntness for Korean audiences, while a reviewer who dropped it found the good-versus-evil lines too simple. Either way, expect catharsis, not a subtle ethics study.

5. Korean details that are easy to miss

Cameras in the operating room are real

One Magnolia Association member resents operating-room surveillance cameras. That is real-world friction. Under Korea's revised Medical Service Act, in force since September 25, 2023, clinics must install cameras in operating rooms used for patients under anesthesia and record when the patient or guardian asks, Yonhap reported; doctors' groups challenged it with a constitutional petition. A villain who hates the cameras tells Korean viewers which side he is on.

SBS's "justice" dramas

SBS places the show alongside Taxi Driver, The Fiery Priest and The Judge from Hell, earlier hits in which an outsider delivers the justice the system will not, and calls it its first medical noir in that line.

The Korean title

The subtitle 하얀 마피아의 시대 (hayan mapia-ui sidae) literally means "the age of the white mafia," white for the doctors' coats.

6. Should you start now or wait?

Our take: start now if you like watching along with a crowd. Netflix rates it TV-MA in the US and surgery scenes are part of the appeal, so skip it if you are squeamish. Wait until November 14 if you hate cliffhangers; all 12 episodes will be on Netflix after the finale, and we found no announcement of a second season.

FAQ

How many episodes does Doctor X: Mafia in White have?

Twelve, two a week; the finale airs November 14, 2026 (Korea date).

Is it the same show as Japan's Doctor-X?

No. Doctor-X: Surgeon Michiko Daimon is the Japanese original with Ryoko Yonekura. Mafia in White is SBS's Korean remake with a new cast and a new, serialized storyline.

Do I need to watch the Japanese version first?

No. The Korean show sets up its own characters from episode 1. The original makes a fun comparison afterward, but it runs 69 episodes.

Is there an English dub?

On Netflix's US page (checked October 22, 2026), yes. Options vary by country.

Bottom line

Doctor X: Mafia in White is this month's K-drama for a reason: a lead to root for, villains to boo, and four episodes you can catch up on in an evening. Episodes 5 and 6 arrive October 23 and 24. Join the weekly buzz now, or bank all twelve for mid-November.
