Kadath, the studio founded by veteran producer Yoichi Miyaji—best known for his work on the Lunar RPG series—has officially announced Under Mythos, its debut title for Nintendo Switch, slated for release in 2028.
The project brings together creators with credits on high-profile Japanese franchises, and the studio released a teaser trailer alongside the announcement that highlights the game's unusual blend of gentle innkeeping and creeping horror.
Background and team
Under Mythos is Kadath’s first project and is marketed as a dark fantasy JRPG.
The development team reportedly includes talent who have worked on Pokemon, Tales of the Abyss, GRANDIA, and LUNAR, underscoring a roster with deep JRPG and Japanese studio experience.
Kadath positions Under Mythos as a game that contrasts peaceful daily life with escalating supernatural threats.
What Under Mythos will play like
Kadath describes Under Mythos as a dark fantasy JRPG that balances tranquil inn management at a mysterious hot spring with action-oriented dungeon exploration.
Players take on the role of a cat who wanders into another world searching for Mother and finds work at a hot spring inn where the realm’s inhabitants come to rest.
The studio explains the game hinges on two core loops: welcoming and caring for guests at the inn, and venturing into dungeons to gather food and resources.
As the narrative progresses, Kadath says the initially peaceful environment will progressively deteriorate as an unpredictable disturbance encroaches on everyday life.
That arc is central to the game’s tone: serene domestic scenes give way to encounters with beings transformed into grotesque forms, which players will confront with action-based combat.
Key features highlighted by the developer include:
- A peaceful innkeeping routine that gradually transforms into a narrative of madness
- Dungeon exploration and real-time action combat against corrupted enemies
- A management and extraction loop where resources gathered on expeditions are used to expand and support the hot spring inn, unlocking new encounters and further exploration opportunities
Teaser and coverage
Kadath released a teaser trailer alongside the announcement; coverage of the reveal was reported by Gematsu.
Under Mythos is confirmed for Nintendo Switch in 2028.
Kadath has not provided additional release-window details for other platforms or eShop availability at this time.
For fans of narrative-driven JRPGs and developers with deep franchise pedigrees, Under Mythos will be a title to watch as more production details and footage become available in the lead-up to its 2028 Switch launch.
