One million yen if you don't flinch. The controller shook anyway.
From October 1995 to March 2000, TV Asahi aired Ucchannanchan no Honoo no Challenger, a variety show where ordinary people attempted extraordinary physical tasks. The breakout segment was the Denryuu Iraira Bou: guide a metal ring along a winding electrified wire without touching it, while cameras caught every tremor. The prize was one million yen. Most people failed. In December 1997, Hudson ported this tension to the Nintendo 64, faithfully recreating all five original TV courses plus new ones. The game did what great variety television does: it made watching someone else struggle feel urgent. But the N64 version added something TV couldn't — you were the one holding the stick. Your thumb trembled now. There is a specific kind of pressure that comes not from danger but from the knowledge that everyone is watching. The Iraira Bou understood that before most game designers did.
About this game
A Japan-only action puzzle game for the Nintendo 64, released in late 1997 and based on a segment from the Japanese variety show hosted by the comedy duo Ucchannanchan. The player guides a rod through a series of increasingly twisted electrified mazes, trying not to touch the walls—a video version of the classic carnival wire-loop game. The same TV segment also inspired arcade and PlayStation titles.

Region & Compatibility
The N64 uses a mechanical region lock rather than a software one: Japanese and North American cartridges share the same NTSC signal, but the physical shape of the cartridge's back shell and the console's slot are different, so a Japanese cartridge will not slide fully into a North American console without modification, and vice versa. The simplest fix is removing the two plastic tabs inside the console's cartridge slot, or swapping the cartridge's back shell — neither requires any electronic modification. PAL (European) cartridges and consoles are a separate case: 50Hz vs 60Hz incompatibility means simple physical modifications are not enough, and a frequency mod is also required.
Maintenance Tips
The N64 cartridge connector is the most common failure point — clean the edge contacts with 90% or higher isopropyl alcohol on a cotton swab every 6 to 12 months, and avoid blowing into the cartridge slot as moisture accelerates pin corrosion. The original analog stick is made with a plastic-on-plastic gear mechanism that wears into a gritty, loose feel over decades of use; check for smooth snap-back to center before buying, and know that replacement sticks are widely available but none have fully matched the original feel. Store cartridges in a cool, dry place and handle them by the plastic shell, not the gold contacts.
What to Watch Out For
Before buying, these are the points worth knowing — from someone who handles original Japanese Ucchannanchan no Honō no Challenger: Denryū Iraira Bō copies regularly.
Will this Japanese Nintendo 64 cartridge work on a North American or European N64?
No, not without modification. The Nintendo 64 uses a regional CIC lockout chip, and Japanese N64 cartridges have a different physical shape from North American cartridges. Running Japanese software on a Western N64 requires both a cartridge adapter to bridge the shape difference and a method to bypass the CIC chip. A Japanese Nintendo 64 console is the simplest way to play Japanese N64 software.
How should I clean a Nintendo 64 cartridge?
Apply 90% or higher isopropyl alcohol to a cotton swab and wipe the gold-plated edge contacts on the base of the cartridge. The N64 connector slot is deep — a longer swab or folded swab helps reach all contacts. Never blow into the cartridge. N64 cartridges use 3.8mm security game bit screws if the shell needs to be opened. Most N64 boot failures trace to oxidized contacts; cleaning both the cartridge edge and the console slot is usually the complete fix.
Before You Buy
Things worth knowing before you buy Ucchannanchan no Honō no Challenger: Denryū Iraira Bō
A short checklist for buying a used Nintendo 64 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 N64 cartridge. The N64 is region-locked by shape and lockout, so a Japanese cart needs a Japanese console or an adapter.
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.
-
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.
