Konami's action RPG on Famicom. Fuuma Kotaro, floating islands, and demons — overworld mixed with side-scroll.
Getsu Fuuma Den was developed and published by Konami for Famicom in July 1987 — an action RPG set in feudal Japan featuring Fuuma Kotaro, a descendent of the Getsu clan, fighting demons across floating islands. The game alternated between a top-down overworld map for island navigation, side-scrolling action stages for combat, and dungeon exploration. Players collected items, leveled up, and purchased equipment. Getsu Fuuma Den sold approximately 1.1 million copies and is cited as an early example of Konami's action-RPG genre experiments on Famicom.
About this game
Getsu Fuuma Den (1987) is one of Konami's most distinctive Famicom titles: a hybrid action game that blends side-scrolling combat with an RPG overworld, dark Japanese mythology, and a samurai protagonist facing the armies of the underworld. Players guide Fuuma Getsu through three hellish realms to defeat the demon king Ryukotsuki and rescue his brothers. Never released outside Japan, it became a foundational text in the vocabulary of dark-fantasy Japanese games — and a cult classic revisited with a roguelike sequel in 2022.
Key Features
The game alternates between two modes: an overhead map where Fuuma moves between stages and collects equipment, and side-scrolling action stages where he fights enemies with his sword, whip, and sub-weapons. Bosses guard the entrance to each hell realm. Experience points and equipment upgrades give the game an RPG skeleton beneath its action surface. The visual aesthetic draws heavily from Japanese Buddhist and Shinto mythology, with grotesque enemy designs unlike anything else on Famicom at the time.

The Story Behind
Released in 1987, Getsu Fuuma Den arrived at the height of the Famicom's creative golden age, alongside Konami's other landmark titles like Castlevania (1986) and Contra (1987). Its decision to blend action with RPG mechanics anticipated the 'Metroidvania' approach years before that term existed. The game's specifically Japanese mythological framing — yokai enemies, Buddhist imagery, a protagonist drawn from samurai legend — made it a touchstone for games that would later define the aesthetic of Japanese dark fantasy.
Tricks & Tales
Getsu Fuuma Den was never officially released outside Japan, yet it has long circulated in translated fan patches among retro gaming communities. The game's hero Fuuma Getsu appeared as a playable character in Konami's crossover titles, keeping the character known even to players who never played the original. In 2022, Konami released GetsuFumaDen: Undying Moon for Nintendo Switch and PC — a roguelike spiritual successor that introduced the franchise to an international audience for the first time.

What to Watch Out For
Before buying, these are the points worth knowing — from someone who handles original Japanese Getsu Fuuma Den copies regularly.
Will this Japanese Famicom cartridge work on a North American Nintendo Entertainment System (NES)?
No, not without an adapter. The Famicom uses a 60-pin edge connector while the NES uses a 72-pin connector with a physically different form factor — the two are incompatible at the cartridge slot level. Third-party adapters exist that bridge the pin difference and allow Famicom cartridges to run in a NES. On a Japanese Famicom, NES cartridges face the same incompatibility in reverse. To play Japanese Famicom software, you need a Japanese Famicom, a Famicom-compatible clone console, or a NES fitted with an appropriate adapter.
How should I clean a Famicom cartridge to ensure reliable play?
Apply 90% or higher isopropyl alcohol to a cotton swab and gently wipe the gold-plated PCB edge contacts on the base of the cartridge. Never blow into the cartridge — breath moisture accelerates contact corrosion over time. If cleaning is needed inside, Famicom cartridges use 3.8mm security game bit screws (not standard Phillips); a security bit screwdriver is required to open the shell without damage. Note that most Famicom boot failures originate in the 60-pin console slot rather than the cartridge itself — cleaning the console slot contacts separately with a contact cleaning tool is often the more effective fix.
Before You Buy
Things worth knowing before you buy Getsu Fuuma Den
A short checklist for buying a used Famicom cartridge wisely — useful with any seller, anywhere.
-
Choose a seller who tests it before shipping
A copy that has actually been powered on and checked is a known quantity. An untested one is a gamble you only settle after it arrives.
Look for a seller who states it was function-tested and says what they confirmed. A serious seller can tell you exactly what was checked.
-
Make sure it fits your console
This is a Japanese Famicom cartridge with a 60-pin connector; a North American NES uses a 72-pin slot, so it will not fit directly.
Play it on a matching Japanese console or a region-free system, and confirm the listing states the region.
-
If this title saves your progress, check the battery
Cartridges that save use a small coin-cell battery that fades over decades — a dead one wipes your save without warning.
Ask the seller whether the save function was tested. Replacing the battery is possible, but doing so erases any existing save.
-
Check that the contacts are clean
Dirty edge contacts are the most common cause of startup and sound trouble in cartridges of this age.
Choose a seller who cleans the contacts before shipping. A note that it was tested and cleaned means the basics were handled.
-
Confirm it is genuine, not a reproduction
Sought-after titles are targets for reproduction boards with replacement labels.
Ask for a photo of the circuit board and look for factory markings. Favour a shop with a licensed second-hand dealer permit (古物商) — by law its stock has a traceable origin, your simplest guard against fakes.
-
Read the seller's reviews and return policy
A 100% positive record across thousands of sales is close to a guarantee — packing, communication and problem-solving all work for everyone. A return policy protects you if something is off.
Read the feedback and confirm a clear return window before you buy.
The last step before buying anywhere is knowing what it's worth.
