Digimon Digital Monsters - D Project (J): WS RPG

Compiled by Alfred J. Hall · Editorial standards · Published June 28, 2026

Digimon Digital Monsters - D Project (J) is a WonderSwan game released exclusively in Japan around the early 2000s. It is part of the Digimon franchise, adapting the digital monster raising and battling concept to Bandai's handheld console. The game was only available in Japan, so all text and menus are in Japanese, making it a niche title for import collectors.

The core gameplay revolves around raising a Digimon from a small form into a powerful partner. You manage its training, feeding, and rest to influence evolution. Battles against wild Digimon are turn-based, where you issue commands to attack, defend, or use special moves. Progression is tied to your Digimon's stats and evolution path, which changes based on care and battle performance.

For retro enthusiasts, this title offers a glimpse into early Digimon gaming on a non-Nintendo handheld. Its monochrome pixel art and simple mechanics reflect the era's focus on pet simulation mixed with light RPG elements. While it won't satisfy fans expecting deep storytelling or complex systems, it is a curious artifact of the WonderSwan's library and a must-try for Digimon completionists.

Getting Started

When you first start Digimon Digital Monsters - D Project, you will choose a starting Digimon from a small selection. The game immediately introduces the basic care system: you must feed, train, and clean up after your partner to keep it happy and healthy. The core loop is divided between managing these needs and venturing into battle areas.

Battles occur randomly or at specific locations. Use the D-Pad to navigate menus and select commands. The A button confirms choices, while B cancels. Winning battles earns experience and items, which help your Digimon evolve. Pay attention to its hunger and fatigue meters - ignoring them will hinder performance.

Since the game is entirely in Japanese, menu navigation can be tricky. A helpful approach is to observe patterns: the first option is often "Battle," the second "Item," and so on. Try using the start menu to save your progress regularly. Experiment with different care routines to see which evolutions you can unlock.
