Kanji Learning Today

Kanji Learning Today is a system that helps a learner remember many kanji within a relatively short period of time.

The system includes three online volumes and three corresponding workbooks.

A feature of the system is that it presents 20 kanji on each page. The user can complete several pages in a single study session. After a few sessions, the user remembers the kanji and builds a reading level.

Coverage of the Kanji Learning Today Volumes

Online 1 covers the 1026 “Education Kanji” (教育漢字). The Ministry of Education specifies that these characters be taught at the Japanese elementary school level. Kanji Learning Today presents the kanji at the same grade levels as the schools, thereby helping the second language learner develop reading ability.

Online 2 presents the 1110 “Graduation Kanji”, a term selected by the editor. The Ministry of Education says these characters will be taught in middle school and high school but does not mandate which characters be taught at a particular grade. The volume, along with the Education Kanji, completes the Joyo Kanji List, which forms a baseline for literacy and circumscribes the characters allowed in official government documents.

Online 3 offers the 863 “Name Kanji” (人名用漢字). These are characters not on the Joyo Kanji List but were deemed important to be allowed to be used in the official registration of people’s names, and are for that reason approved for name use by the Ministry of Justice. For clarity’s sake, it should also be noted that the Joyo Kanji can also be used in people’s names.

Online 1 is offered free of charge and will be present on the Member page after login.

Online 2 and Online 3 are available in the Shopping Cart and will appear on the Member page after purchase.

Kanji Learning Today — Workbook

The Kanji Learning Today system includes three workbooks.

For additional information, see Kanji Learning Today.

kltNotes Introduction

kltNotes is a series of posts on social media that provide additional information about Kanji Learning Today.

There are several reasons for providing the additional information as posts.


Accessing the kltNotes

kltNote Example

The following example shows a kltNote with the image above and the text below.

kltNote example

海、かい、sea, ocean、2-1-14
毎、まい、every, each ~、2-8-5

In the above example, the target kanji is located at 2-1-14, which refers to Year 2, Set 1, Position 14 (Year 2 is in Workbook 1), the kanji-in-kanji is identified, and the source kanji is shown to be located at 2-8-5.

The intent is to help the user be aware that a particular portion of the target kanji contains a fully formed separate kanji. There may be a similarity of readings or connection in meaning, but even if such a connection is not apparent, becoming familiar with the relationship can be helpful in removing the mystery of “Where did I see that kanji before?”
