Evaluation

I am an Air Traffic Controller 4 launched on October 15, 2020, and received five paid airport DLC expansions over roughly four years: Airport NAHA (August 26, 2021), Airport NEW CHITOSE (February 15, 2023), Airport OSAKA (September 20, 2023), Airport NAGOYA (March 28, 2024), and Airport NARITA (May 20, 2025). This established a consistent cadence of roughly one major airport DLC per year. All listed DLC is now released, and no new ATC4 airport DLC has been announced. The developer's communications since early 2026 have shifted entirely to BOKUKAN5 TOKYO (HND), the next entry in the series — confirmed for a 2027 release, with a demo released on July 30, 2026, and a detailed roadmap outlining planned features for that new game. TechnoBrain has made no mention of additional ATC4 content in any of these posts. The last airport DLC (Narita) shipped on May 20, 2025. Given the established annual DLC cadence, a follow-up would have been expected by approximately May 2026 — that window has now passed (today is August 27, 2026) without any announcement. The developer is clearly active and communicating regularly, but all development energy is directed at BOKUKAN5. With no new ATC4 DLC announced, the cadence window exceeded, and the studio visibly pivoting to a successor title, the most reasonable conclusion is that ATC4's paid content cycle has concluded with the Narita DLC.
Evidence
TechnoBrain released a demo and detailed roadmap for BOKUKAN5 TOKYO (HND), the next series entry targeting a 2027 release. All planned content and future development is focused on this new title, with no mention of additional ATC4 content.

About this game

[About "I am an Air Traffic Controller 4"]

Since its release in 1998, this air traffic control game has established itself as a long seller, strongly supported by numerous users both inside and outside of aviation fandom.

For the safe flight of aircraft, air traffic controllers play a vital role. We focus on the duties of these controllers in our game scenarios.

[How to Play]

To clear the stages, a player should issue directions as a tower controller for safe and effective flight of aircraft. The operation is quite simple, just select an aircraft and click Instruction buttons. Yet as the situation keeps changing according to the directions issued and the timing, clearing the stage always requires precise and correct judgment. Even after game over, you can resume from the middle of the game replay.

[Various Stages Available]

Adding to the Game Stage of various play levels, the Extra Stage gives you some special conditions to further liven up the play. You can also select time, wind direction, and section you like for your own Original Stage.

[Airport Covered]

The game is set in Haneda Airport (HND/RJTT) in Tokyo, which represents Japan!

It is Japan's largest airport both in its reputation and in its performance, as it sports no less than four runways, handling over 80 million passengers annually (domestic/international), with over 400,000 flight slots.
