That '4.5/B' on the Listing Isn't a Zip Code: Cracking Japan's Auction Grade Code

You've found it: a 1998 Honda Acty, listed by a dealer in Gunma, priced like a used riding mower. The listing says "4.5/B" and includes what looks like a faxed scan of a form covered in Japanese handwriting. If you're wiring several thousand dollars across the Pacific based on vibes alone, stop right there.

That form is an auction sheet, and it's the single most honest document you'll ever get about a Japanese used vehicle. Learn to read it and you'll shop like a local. Ignore it and you're buying someone else's rust problem sight unseen.

What the Number Actually Means

Japanese auction houses grade vehicles on a scale, and the number tells you overall condition:

• 7 or S — Essentially new. Rare on anything older than a few years.
• 6 — Very clean, minor wear.
• 5 — Good condition with light cosmetic flaws. The sweet spot for most imports.
• 4.5 — Very good for its age. A 25-year-old kei truck graded 4.5 has been genuinely cared for.
• 4 — Solid, honest condition. Some visible wear, nothing alarming.
• 3.5 — Noticeable dents, scratches, or paint fade. Budget for cosmetic work.
• 3 — Rough. Multiple issues, possibly panel repairs.
• R or RA — Repair history. The vehicle has been in an accident or repaired. Not automatically a dealbreaker, but the price should reflect it.

A dealer in Maebashi listing a "4.5" Acty is telling you something real: inspectors at auction examined that truck and found it exceptionally clean for its age.

Decoding the Letter

The second character is the interior grade:

• A — Excellent interior, close to factory condition.
• B — Good interior with light wear. A torn seat seam, maybe some dash fade.
• C — Visible wear — stains, odors, cigarette burns.
• D — Worn out. Think of a truck that lived its life on a farm with a smoker at the wheel.

So "4.5/B" means: excellent body and mechanically sound, good but not perfect cabin. For a work truck, that's about as good as it gets.

The Inspector's Scribbles

Here's where it gets interesting. The auction sheet includes handwritten notes, often in shorthand, flagging specific issues. Common ones:

• A1, A2, A3 — Dents, sized 1 through 3. An A1 is a parking lot ding; A3 is body shop territory.
• U1, U2, U3 — Scratches, same sizing logic.
• S — Rust. Yes, Japan uses "S" for sabi (rust). Kita-Kanto winters bring road salt, so check for this on any kei vehicle.
• XX — Replacement part, often marked with what was swapped.
• W — Wave or repair mark in the paint.
• P — Paint fade or dullness.
• F — Small dent or ding (sometimes paired with a number).

A sheet reading "A1 U2, front bumper S" translates to: one small dent, a couple of scratches, rust on the front bumper. Perfectly normal for a 25-year-old work vehicle — and great negotiating material.

Red Flags Worth Wiring Nothing Over

Some notations should stop you cold, or at least prompt a phone call:

• R-grade with no repair details — What was hit, and how was it fixed?
• Extensive S markings on the frame or underbody — Structural rust on a kei vehicle can cost more to fix than the truck is worth.
• Mileage discrepancies — Japanese odometers are rarely rolled back (it's illegal and tightly policed), but verify the shaken (inspection) records match the auction sheet.
• "No rebuild engine" denials — Some sheets will note "Hirei" (engine swapped) or "Saikougu" (rebuilt). Not necessarily bad, but know what you're buying.

Your Cheat Sheet, Ready to Use

Print this and keep it next to your keyboard when browsing Kita-Kanto dealer listings:

Code	Meaning
4.5 / 5	Excellent / good body
R / RA	Accident or repair history
A1–A3	Dent, small to large
U1–U3	Scratch, small to large
S	Rust (sabi)
W	Paint repair wave
XX	Replaced part
P	Paint fade
B / C	Interior good / worn

The Bottom Line

The auction sheet is your best friend because it was written by someone with zero incentive to sell you anything. Inspectors at Japanese auctions are independent, and their reputations depend on accuracy. A dealer who shares a full, legible auction sheet — not a cropped photo — is a dealer worth trusting.

When you're evaluating that Acty or N-BOX from across the ocean, don't just look at the pretty photos. Ask for the sheet, decode the scribbles, and wire your yen with confidence. Your future kei truck — and your wallet — will thank you.
