K-Pop 2026: The Ultimate Guide to Military Enlistments and Discharges

The South Korean music industry is entering a critical transition phase this second quarter of 2026. For entertainment giants like JYP, SM, and Pledis, managing military enlistment schedules has become a major strategic challenge to maintain global chart visibility. Here is the comprehensive update on official movements and enlistment forecasts starting from April 2026.

Imminent Departures: The '98 Line Heading to Service

As of April 2026, pressure is mounting for idols born in 1998 who are reaching the legal age limit for deferring their active duty.

Lee Know (Stray Kids): The main dancer of the JYP powerhouse is a top SEO search priority this month. As the eldest Korean member, his enlistment is expected by late spring or early summer 2026. Unlike Bang Chan and Felix, who are exempt due to their Australian citizenship, Lee Know will join an infantry unit, marking the first time the group will operate with a reduced lineup.

Seungkwan (SEVENTEEN): An indispensable vocal pillar, Seungkwan is expected to finalize promotional activities with SEVENTEEN before joining the army by summer 2026. Given his past health history, he may be assigned to a public service worker position, which would extend his service period to 21 months instead of 18.

Jungwoo (NCT 127): The charismatic NCT member is preparing to begin his enlistment procedures. His upcoming departure following Jaehyun’s service creates massive anticipation regarding NCT's new structure for 2027.

Under-the-Radar but Crucial Profiles: Other 4th generation artists are also beginning their service this month. Hongjoong (ATEEZ) and Seonghwa, both born in late 1998, are at the heart of fandom discussions. Even with ATEEZ at the peak of their international popularity, Korean law no longer allows deferments beyond May 2026. We also note Hwanwoong (ONEUS) and Kevin (The Boyz), whose respective departures will force their labels to launch unprecedented solo projects or sub-units.

Military Discharges: The Return of Idols in 2026

While departures are difficult, April and May 2026 mark the return of several iconic figures who will breathe new life into their groups.

Jaehyun (NCT): This is the major event of next month. His official discharge date is set for May 3, 2026. His return is already anticipated by SM Entertainment investors, who expect a solo album or a special unit by the third quarter.

Jeonghan (SEVENTEEN): The first SEVENTEEN member to leave will complete his service on June 25, 2026. His return signals the start of the group’s progressive reformation, a key moment for fans waiting for the full group's military era to end.

Hyungwon (MONSTA X) and Kim Woo-seok: Their releases scheduled between May and June 2026 will revitalize the K-Drama market, as both artists already have filming projects pending their return to civilian life.

Technical Analysis: Why Do Some Stay Active?

A question generating significant traffic is the exemption of certain members. It is important to clarify that idols with dual nationality or foreign passports, such as Joshua (SEVENTEEN) or Stray Kids' "Aussie Line," are not subject to enlistment. This strategy allows groups to maintain a constant presence in the US and European markets while Korean members fulfill their obligations.

FAQ: Burning Questions for April 2026

What is the exact duration of military service this year? For the Army and Marines, the duration is 18 months. It rises to 20 months for the Navy and 21 months for the Air Force or civil service.

Can they release music during their service? No, commercial profit is strictly prohibited. However, agencies pre-record dozens of contents (videos, songs, photos) that are released on a schedule so that the idol never truly "disappears" from social media.

Conclusion: A Year of Transition for K-Pop

2026 is proving to be a pivotal year for the Korean music industry. Between the temporary farewells of 4th generation leaders like Lee Know or Hongjoong and the strategic return of 3rd generation pillars led by Jaehyun in May, the balance of power is in full motion.

For agencies, the challenge is no longer just managing an absence, but transforming this waiting period into a marketing lever through solo projects, sub-units, and pre-recorded content. For fans, it is a year of patience but also celebration. Stay tuned to catch every official discharge or enlistment date, because in this ever-evolving universe, every return marks the beginning of a legendary new era.
