第 I 章 — Why we exist

The secondary market runs ontrust.
We substantiate that trust
with the eye of Japanese craftsmanship and a record that lasts.

The pre-owned luxury market is made up of singular pieces, each one different from the next. Even when the model number is the same, year, specification, accessories and condition all change the value. To handle that complexity correctly, you need both the eye of authenticators who understand the trade deeply and a record that keeps the evidence behind every verdict.

IJBA Verify has a team of seasoned authenticators holding a Japanese Antique Dealer License (kobutsusho) record the authenticity and condition of each item together with supporting evidence. An image-analysis AI to assist our authenticators is under development; we will announce it once a launch date is set. Every digital certificate can be verified by anyone via QR code. It is not merely a document, but an ongoing guarantee of trust.

“In the pre-owned luxury trade, trust is the only currency.
We guarantee it — with the eye of a craftsman,
and a record that lasts.”

For two kinds of clients.Two distinct paths — equally cared for.

Ⅰ For Retailers — Trade

The operational backbone for stores,
authentication + inventory on one platform.The operational backbone for pre-owned luxury retailers.

Authentication requests, inventory registration, in-store sales, consignment control, EC listings and purchasing history are managed from a single dashboard. It is an operational OS built for the realities of one-of-a-kind inventory.

  • Piece-level management — track history by item, not by SKU
  • Role-based access for each staff member (owner, manager, staff, trainee)
  • CSV export of listing data for major marketplaces
  • Purchase → authentication → sale history recorded per item
  • Automated Antique goods ledger / compliance support
  • A common photo guide for scale and efficiency — aligned with the same guide used for private clients. Bulk uploads remain efficient under one standard, without demanding exact matches or ignoring retailer shooting practices.
Request retailer materials →
Ⅱ For Consumers — Private clients

So each piece can stay
safely in your hands.Peace of mind for every owner and every buyer.

Your item can be authenticated while remaining with you. Simply follow the photo guide, take a few images with your phone and upload them. No shipping. No visit required. Results remain available on your account page whenever you need them.

  • No need to ship the item — it stays with you throughout
  • Result within 3 days, as soon as the same day
  • Completed with smartphone photos only
  • Third parties can verify authenticity through the certificate QR code
  • Pre-purchase verification for flea-market and peer-to-peer transactions

第 IV 章 — INVENTORY MANAGEMENT

A control panel built
for singular inventory.A back-office built for one-of-a-kind inventory.

Most existing EC tools assume there are multiple units of the same product. Pre-owned luxury does not work that way. IJBA Verify was designed from the outset around a simple idea: one item, one record.

— i.
Item ID
Linked to the certificate number so the history remains continuous.
— ii.
Consignment separation
Clear distinction between owned inventory, consignment and pledged custody.
— iii.
Listing data export
CSV export for major marketplaces. Automatic sync is under development.
— iv.
Antique goods ledger
Automatically generated in the National Police Agency format and ready to print.
