■ Background: The Challenge of "Fragmented Information" in the Ancient Coin Market

In recent years, the antique coin market has continued to expand globally due to growing interest in asset management and historical value. However, advanced research findings, auction data, and knowledge regarding authenticity of Japanese ancient coins were scattered across academic books domestically and internationally, and on overseas websites, posing a high hurdle for general collectors to access accurate information.

ITTENDO was established with the aim of resolving this "information asymmetry" and creating a state where anyone can learn correctly and judge value for themselves. It is Japan's largest Japanese ancient coin media.

■ Three Values Provided by "ITTENDO"

Rather than being a mere catalog site, it aims to be a "learning media" that helps readers "develop a keener eye the more they read," and offers the following functions:

・Aggregation and Translation of Global Information 

Collects information on Japanese ancient coins scattered across overseas auction houses and research institutions. Overcomes language barriers and publishes it in an easily understandable, organized Japanese format.

・Systematic Organization Connecting Beginners to Experts 

Systematizes the complex classification of ancient coins while breaking down specialized terminology. Achieves a structure that even beginners can intuitively understand.

・"Coinpedia" to Cultivate Standards for Value Judgment 

Includes "Coinpedia," a knowledge base for ancient coin investment. It goes beyond simply presenting prices, covering the background knowledge of "why a certain value is assigned."

■ Pillar of Content: The Knowledge Base for Ancient Coin Investment, "Coinpedia"

Particular focus is placed on guide content that covers how to read ancient coins and points for authentication.

Reading Guide: Provides basic knowledge for deciphering unique fonts and inscriptions.

Knowledge Base for Ancient Coin Investment: Delves deeply into the asset aspect, including market trends and how to view preservation conditions (grades). (Details: https://www.ittendo.com/coinpedia/guide )

■ Future Outlook

ITTENDO aims to be a platform that connects Japan's proud monetary culture to the next generation. In the future, we will continue to disseminate the value of Japanese ancient coin culture both domestically and internationally, while ensuring the fairness of information, by expanding the database of the latest auction prices and providing high-resolution archives for authentication.
