The judgment never checks the whole road — only the last stretch of it.
A boy named Tarosuke is dragged to the gate of hell in his sleep, punished for the mischief of his waking hours. That much is a familiar way to start an underworld story. Namco's twist is in *when* the verdict actually gets calculated.
Yokai Dochuki does not tally the whole trip. Its five endings — heaven, the human realm, the animal realm, the realm of hungry ghosts, hell — are decided entirely by what happens inside the final stage alone: how much money is collected there, how many enemies fall there. Everything gathered on the long road before it is already spent, already off the ledger.
The Famicom version adds a stranger wrinkle: a hidden stat called Pious, a measure of good conduct. In that same final stretch, killing too freely and hoarding too much money pulls Pious down. The habits that carried a player safely through every earlier stage — fight, collect, push forward — start working against them the moment they're played at the same volume in the last one.
In February 1988, when Namco introduced itself to a brand-new machine called the PC Engine, this is what it chose to send first. Not a mascot. Not a spectacle. A boy, hell, and a verdict that only looks at the end.
About this game
A side-scrolling action game from Namco. A boy named Tarosuke is taken to the underworld in his sleep as punishment for his mischief, and must make his way through it. The arcade original ran from April 1987; this PC Engine version, released on February 5 1988, was Namco’s first title for the machine. Five endings — heaven, the human realm, the animal realm, the realm of hungry ghosts, hell — are decided by the final stage alone.

The Story Behind
Yokai Dochuki began as a Namco arcade title in April 1987, at a time when the company was refining ‘scoreless’ game design following 1986’s Tower of Druaga sequel, Return of Ishtar. The PC Engine version, released February 5, 1988, became Namco’s first title for the new console — a significant moment for the platform, as PC Engine relied on just two publishers (Hudson and Namco) until later that year. The game’s underworld setting — with heaven, the human realm, the animal realm, the realm of hungry ghosts, and hell as its five endings — drew from Buddhist cosmology’s ‘five realms’ (rokudō, with the asura realm deliberately excluded).
Tricks & Tales
The five endings are determined entirely by what happens inside the final stage alone — money collected and enemies defeated in that last stretch — with no accounting for earlier stages. The Famicom version introduced an additional hidden stat called ‘Pious,’ which decreases if the player kills too many enemies or hoards too much money in the final stage, meaning the habits that worked all game suddenly work against you at the end. A sixth ending, ‘Geemu-kai’ (Game Realm), exists only in the Famicom version. Namco chose this underworld-walking tale as its very first PC Engine release.
Collector's Guide
Region & Compatibility
The PC Engine (Japan) and TurboGrafx-16 (North America) share the same physical HuCard slot shape but are not compatible with each other's software. NEC deliberately reversed the data bus wiring between the two regions: data pin D0 on the PC Engine corresponds to D7 on the TurboGrafx-16, and so on through all eight lines. Beyond the hardware wiring difference, most North American HuCards contain region-checking code that detects a Japanese console and immediately crashes. Converters that electrically flip the data bus do exist and allow cross-region play. CD-ROM² discs themselves carry no region protection and play freely on both systems—however, the System Cards required to boot CD software are region-locked in the same way as HuCards, so a Japanese System Card cannot be used in a TurboGrafx-16 and vice versa.
Maintenance Tips
HuCard contacts are the most common maintenance point on the PC Engine and TurboGrafx-16. The card's edge connector oxidizes over decades of storage, causing failure-to-read and graphical glitches. Cleaning with 90%+ isopropyl alcohol on a cotton swab—gently wiping the gold contacts on the card itself—resolves most contact issues; stubborn oxidation responds to dedicated contact cleaners such as DeoxIT. Never blow into the card slot with your mouth, as moisture accelerates the very corrosion you are trying to remove. On systems equipped with the CD-ROM² or Super CD-ROM² add-on, the optical drive is subject to the same age-related laser and sled degradation seen in any CD system of that era; the laser assembly uses a KSS-220a-type unit on the Super CD-ROM² and replacement parts remain available.

What to Watch Out For
Before buying, these are the points worth knowing — from someone who handles original Japanese Yokai Dochuki copies regularly.
Does this game save progress, or do I play through in one session?
Yokai Dochuki has no save or password system — it’s designed to be played in a single session from start to finish. The PC Engine HuCard format stores no save data, so there’s no battery to replace and nothing to worry about losing over time. When you finish, you finish; when you stop, you start over. That’s how it was made.
Will a Japanese PC Engine HuCard work on a TurboGrafx-16?
Not directly. Japanese PC Engine HuCards and North American TurboGrafx-16 HuCards are physically identical, but the consoles enforce region locking at the BIOS level. A Japanese card inserted into a TurboGrafx-16 will usually display a region error screen. Region adapters exist, but the most straightforward path to playing Japanese PC Engine software is a Japanese PC Engine console.
How should I clean a PC Engine HuCard?
Use a cotton swab dampened with 90% or higher isopropyl alcohol to gently wipe the gold-plated edge contacts on the card. Let it dry completely before inserting it into the console. The HuCard format is physically robust — most boot failures are dirty contacts rather than damaged cards. Never blow into the card or the console slot; the moisture accelerates corrosion.
Before You Buy
Things worth knowing before you buy Yokai Dochuki
A short checklist for buying used PC Engine software 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
Japanese PC Engine HuCards and CDs are not compatible with the North American TurboGrafx-16 — the formats differ. Use a Japanese PC Engine system.
Play it on a matching Japanese console or a region-free system, and confirm the listing states the region.
-
HuCard or CD-ROM² — know which you're buying
PC Engine games come on HuCard chips or on CD-ROM². CD titles also require the right CD system and a working System Card.
Confirm the format in the listing, and for CDs check the disc surface and that saves are supported.
-
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.
-
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.
