There is no confirmed one-for-one replacement for The New Denpa Men. If you want to keep collecting creatures and building a party on Switch, DRAGON QUEST MONSTERS: The Dark Prince is the strongest supported alternative in the available listings. For the closest connection to Denpa Men’s premise, the earlier 3DS game THE DENPA MEN: They Came By Wave is worth knowing about, but current access is not confirmed. Genius Sonority has announced that THE NEW DENPA MEN service ends December 7, 2026, at 11:00 JST.

What happens when The New Denpa Men shuts down?

Genius Sonority announced on October 5, 2026, that service for THE NEW DENPA MEN will end on Monday, December 7, 2026, at 11:00 JST. Sales of paid items, including Jewels and packs, ended October 5 at 11:00 JST. The company says in-game data, including Jewels and items, will no longer be available after service ends. Read Genius Sonority’s official end-of-service announcement.

The announcement says unused paid currency will be refunded under Article 20, Paragraph 1 of Japan’s Payment Services Act. The refund request period and procedure will be published after service ends. If you may have a refund claim, note your Support ID and keep the app installed until the process is complete. The ID can be checked through the app’s Support section until March 31, 2027; Genius Sonority advises against deleting the app or reinstalling it on a new device before the refund process is complete.

The announcement does not specify whether any part of the game will remain playable offline after service ends. A player asked whether the game would become unplayable because it requires an internet connection, but that question does not establish the post-shutdown outcome. Until Genius Sonority clarifies it, treat offline playability as unknown rather than assuming either that the app will work or that every feature will stop.

What makes The New Denpa Men hard to replace?

Nintendo describes the game as a free-to-play RPG built around catching Denpa Men associated with radio waves, making them companions, and taking them on adventures. Nintendo says each radio wave carries different information, which makes each Denpa Men unique. The official listing also includes character development, island decoration, fishing, battles against other players’ parties, voucher collection, and “Together Catch” with up to four nearby players. See Nintendo’s game listing.

That combination matters when choosing an alternative. A game can match creature recruitment and party building without matching the radio-wave collection idea, island activities, or nearby multiplayer. The following options are partial matches, not substitutes for every part of the original.

Best researched alternatives to The New Denpa Men

Game What it matches What is not established by the cited listing Platform and access
DRAGON QUEST MONSTERS: The Dark Prince Monster recruitment and building an army for battles; a paid Nintendo Switch RPG. Radio-wave catching, island activities, fishing, local Together Catch, and other Denpa Men-specific systems. Nintendo Switch listing; the cited listing does not establish regional inventory or purchase availability.
THE DENPA MEN: They Came By Wave Closest thematic match: catching Denpa Men, forming a party, dungeon exploration, and adventures. Whether it can currently be purchased or downloaded in a reader’s region. Nintendo UK lists it as Nintendo 3DS download software; present storefront access is not confirmed.

DRAGON QUEST MONSTERS: The Dark Prince — best supported Switch option for monster parties

Nintendo’s Switch listing describes Psaro becoming a Monster Wrangler and creating an army of monsters for battle. That makes this a sensible option if the part you most want to preserve is recruiting creatures and assembling a battle-ready party. Check Nintendo’s listing for DRAGON QUEST MONSTERS: The Dark Prince.

The cited listing does not establish that it has Denpa Men’s radio-wave-based catching, island decoration, fishing, voucher collection, or local Together Catch. Choose it for the monster-party RPG element, not as a claim that the two games have the same overall structure.

THE DENPA MEN: They Came By Wave — closest premise, but check access first

Nintendo UK describes this earlier Denpa Men game as a dungeon-based RPG in which players catch Denpa Men, form a party, and go on adventures. Of the cited options, it is closest in theme and core premise. See Nintendo UK’s listing for THE DENPA MEN: They Came By Wave.

The listing identifies it as Nintendo 3DS download software, but it does not confirm that it remains available to buy or download. Check the relevant regional storefront and your access to the platform before relying on it as a playable option.

Which version of The New Denpa Men are you playing?

Genius Sonority’s April 6, 2026, release notice says the Switch 2 version supports cross-platform play and save data with the Switch version when both use the same Nintendo Account. The company describes the game content as identical, with smoother visuals from a higher refresh rate and higher resolution on Switch 2. This helps identify the version in use; it does not clarify what will work after service ends. See Genius Sonority’s game announcements.

How to choose based on what you want to keep

  • Creature collecting and party building: Start with DRAGON QUEST MONSTERS: The Dark Prince if you want a supported Switch option centered on assembling a monster army.
  • The Denpa Men premise and dungeon RPG play: Look into THE DENPA MEN: They Came By Wave, but verify current access for your region and platform.
  • Island life, fishing, or nearby group catching: The cited listings do not establish those features in either alternative, so neither can be recommended as a confirmed match for those activities.
  • A free-to-play replacement: The New Denpa Men is listed as free-to-play, but the two cited alternatives do not establish a matching free-to-play model. Check each game’s current listing for its terms before deciding.

Genius Sonority explained its decision in the shutdown notice: “However, we have concluded that it will be difficult to continue providing a service that meets your expectations, and we have decided to end the service.”
