100 Days of Deception Across Korea: 6 Spots (1 Reported)

About the drama

100 Days of Deception (100일의 거짓말) is a tvN weekend series and a special project marking tvN’s 20th anniversary. It premiered on 10 October 2026, airs on Saturdays and Sundays at 21:10 KST, and runs for 16 episodes. In South Korea it streams on TVING, and internationally it streams on Netflix.

The series was written by Ryu Bo-ri and directed by Yoo In-shik and Kim Yoon-jin, and produced by Studio Dragon and Nangman Crew (rendered as Romantic Crew in some English-language coverage). Yoo In-shik previously directed the Dr. Romantic series and Extraordinary Attorney Woo, and Ryu Bo-ri wrote Do You Like Brahms? — credits that were a stated reason the leads chose the project, according to pre-premiere press coverage.

The story is set in 1932 Gyeongseong, the name for Seoul under Japanese colonial rule. Lee Ga-gyeong (Kim You-jung) is Gyeongseong’s most skilled pickpocket and con artist. Her goal is personal: save enough money to leave Joseon and start a new life in America. The independence movement offers her a deal — go undercover as a trainee interpreter at the Japanese Government-General of Korea for 100 days. She takes it. Inside the Government-General she crosses paths with Kim Tae-woong (Park Jin-young), an elite interpreter also known as Sato Hideo, the adopted son of Director-General Sato Shinichi (Jin Seon-kyu). The cast also includes Kim Hyun-joo as Yoo So-ran, a sniper working for the independence cause, and Lee Moo-saeng as Yoo Philip, a Korean-American correspondent.

The spy-romance engine is the interpreter’s double role: language work inside the colonial administration becomes the cover for the independence mission. That cover — a pickpocket turned secret agent working alongside an elite Government-General interpreter — is the premise the 13 October VFX reports restate, and it is why so much of the drama’s world is offices, stations and streets rather than battlefields. The opening episodes drew first place in their time slot in their first week, per Nielsen Korea figures reported by bntnews — a ratings note, not a location claim, and it says nothing about where any scene was shot.

After its first two episodes, the series entered Netflix’s TV-show Top 10 at No. 5 as of 13 October, according to OTT ranking site FlixPatrol as reported by allkpop. Press coverage of those opening episodes notes that they open at Gyeongseong Station, the colonial-era railway gateway where the main characters’ paths first cross.

Filming locations

Six stops are listed on this page: Nonsan’s Sunshine Land — see also our Nonsan Sunshine Land guide — plus two fan-spotted stops added Nov 7, 2026 from episodes 5–8 (Andong Gunja Village and the Sinheung-dong Japanese-style House in Gunsan), two fan-spotted stops added Oct 31, 2026 (Unhyeongung Yanggwan in Seoul and Mungyeong Saejae Open Set) and one fan-spotted stop from the October weekly update (Hapcheon Film Theme Park). More locations will be added as episodes air and sources confirm them. Sunshine Land is a city-run cultural complex in Yeonmu-eup, Nonsan, combining military-experience facilities with a 1950s-era studio area, according to Nonsan City’s own page — a broader place than a single period street. In March 2026 Nonsan City agreed a filming arrangement with the production, and the grounds were announced before broadcast as a main filming location for the series. The stop stays Reported, not Confirmed, for reasons this guide keeps explicit: all coverage traces to that single March 2026 agreement as one source family, with no second independent source naming this drama at the site, and the cited press account describes an agreement for a new drama at the site without naming this title. Which scenes were filmed there will be noted after episodes air, and no scene is described here. The operator distinction matters, and one part of it stays unresolved: Sunshine Studio, the paid drama set on the grounds, is run by a separate operator from the city-run Sunshine Land grounds, and the agreement coverage does not specify whether the drama used the Studio set, the Land grounds, or both — so this guide claims neither. The Studio set was originally built for Mr. Sunshine and has since been reused for other period productions such as Pachinko and Tale of the Nine Tailed 1938, according to VisitKorea. That history explains why the grounds suit a 1932 story; it is context only, not evidence that any scene of this drama was shot there.

Planning a visit: keep the two addresses apart, because they belong to two areas rather than contradicting each other — the wider Sunshine Land grounds are listed at 102 Bonghwang-ro, while the paid Sunshine Studio entrance is listed at 90 Bonghwang-ro, both in Yeonmu-eup, Nonsan. Sunshine Studio is open 10:00–18:00 with last entry at 17:30, and parking there is free, according to VisitKorea; VisitKorea’s average time spent at the Studio alone is about one hour, so allow longer if you also cover the wider grounds. Two details are unverified and are not asserted here: the closed weekday is Wednesday in the Nonsan listing but Thursday on VisitKorea’s Studio page, so check before you go; and VisitKorea confirms a child admission rate only, so a matching senior rate is unverified in this pass. Free admission to the 1950 Studio zone is likewise unverified — supported only by tourism-listing aggregators in this pass, so check before you go. Rail travel from Seoul to Nonsan is roughly in the 1.5–2 hour range depending on the train/route; check times and fares on Korail at https://www.korail.com/ticket/reserve/train-timeTable. No station-to-site transfer detail is added here: no official source verified in this pass covers it.

Much of the 1932 city — including Gyeongseong Station and the period streets — was recreated with visual effects by Dexter Studios, according to 13 October reports from bntnews and TopStarNews. For those scenes there is no real-world station to visit: the VFX work is the location. Dexter Studios built the 1932 cityscape — station, streets, buildings and period atmosphere — from historical records and reference material, because so little of that city survives today. The reported aim was for the effects to blend into the performances and story rather than stand out as effects. That is why this guide treats the recreation, not a surviving building, as the answer for those scenes: there is no visitable filming site to list for them, and no station, exit, fee or opening hour is attached to them.

The real station behind the drama’s Gyeongseong Station is today’s Seoul Station. Construction of the old Seoul Station building began on 1 June 1922 and finished on 30 September 1925; the station was called Gyeongseong Station from 1923 until it was renamed Seoul Station on 1 November 1947. The old building survives today as Culture Station Seoul 284, a cultural space. It is a historic building worth visiting for its own sake — it is not a filming location for this drama, and this guide does not list it as one. The building was restored over two years under a city regeneration programme and reopened as a cultural complex hosting exhibitions, performances and workshops. Its interiors preserve the historic station fabric, including a stained-glass ceiling feature, and a restoration exhibition shows items found during the works. For a visit on its own terms, VisitSeoul lists the address as 1 Tongil-ro, Jung-gu, Seoul, hours 11:00–19:00, closed Mondays, admission free, with free guided tours at 11:30, 14:00, 15:00 and 16:00, also closed Mondays. Some non-official listings give a 10:00 opening instead, so check before you go — the building also closes during exhibition changeovers. No subway exit number is given here: no official source verified in this pass states one.

What we know: the premiere details, the cast, the Sunshine Land announcement, and the Dexter Studios VFX work. What we don’t know yet: which specific scenes were filmed at Sunshine Land, whether the Studio set or the Land grounds (or both) were used, and whether any other Korean locations appear in later episodes. Also unresolved: the Studio’s closed weekday and senior rate (both marked as unverified above). What is not a location here: the VFX-recreated station and streets, the 1930s hero photograph above (a historical image, not a set), and Upo Wetland — no source in this pass links Upo Wetland, or any place called ‘우포리’, to this drama, so it is not listed. This guide is updated weekly as episodes air, and new spots are added only when a source confirms them.
