About
Summary
Introduction
WAJI is a fully independent and private initiative dedicated to Japanese
characters. It began in 2005 as a simple collection of kanji. Over time, that collection grew in both size and
complexity and eventually evolved into the Kanji Database (KDB).
As work on the Kanji Database progressed, new requirements emerged and led to the development
of additional related projects. The first of these was
Glyph-Master FX (GMF), an advanced glyph editor and browser application, followed by a
sophisticated search engine for Japanese character data with the name Kanji-Galaxy (KGC).
Later, to help both myself and others learn Japanese characters more effectively, development
began on an innovative learning platform Moji-Brain (MJB).
Objectives
The main goal of WAJI is to become a leading source for everything related to Japanese
characters.
This goal will not be achieved simply by gathering vast amounts of data. It also requires
critical review, careful verification, and a strong commitment to quality and accuracy. To meet this standard,
WAJI follows a radically different approach to collecting, correcting, comparing, and correlating information
(4C method) supported by modern information technologies and tools.
Another important objective is to foster a friendly and collaborative community where
everyone interested in Japanese characters is welcome to participate, share knowledge, and engage in discussion.
Motivation
My long-standing fascination with Japan, its diverse culture, and its beautiful language
naturally led me to a deeper interest in its unique and complex writing system.
After consulting countless books and other sources, several major problems became clear:
Fragmented and Limited Resources
Most available references on Japanese characters are either highly specialized or limited in
scope. Many cover only a fraction of existing characters, while others focus only on specific aspects such as
readings, variant forms, or historical details. A comprehensive and unified source of information is still
missing.
Limited Digital Availability
Even today, many Japanese characters remain digitally unavailable because they are not
supported by character sets or fonts. Without unique code points and usable fonts, unsupported characters can
often only be represented through impractical workarounds such as images.
Quality and Accuracy Problems
Although many valuable resources on Japanese characters do exist, the quality and correctness
of some so-called leading references and international standards are not satisfactory. Some even contain obvious
errors, which should not be acceptable in authoritative sources.
Lack of Correction and Consistency
There is also a troubling lack of willingness to correct clear mistakes and long-standing
inconsistencies that have accumulated over time. For example, kanji with controversial or variable stroke order
such as 必, 左, and 右.
Progress
Although WAJI has been in development for more than 20 years, with only
limited public
announcements, substantial progress has been made behind the scenes, mostly in the areas of data collection,
database
design, and backend development.
Along the way, it was also necessary to learn and master many new skills, technologies, and
workflows. These included UI/UX design, data engineering, data governance, data analytics, server
administration, deployment and operations, automation, computer vision, and machine and deep learning.
Conclusion
For these reasons, there is a clear need to address the problems outlined above and to
provide a better solution.
Another powerful motivation is that WAJI and its applications, despite being
created as a
spare-time project with very limited resources, have already developed into highly capable solutions. In many
respects, they now rival, and sometimes even outperform, today’s best available sources and solutions.
