Hello tyuusha. Yes this
https://rutr.life/forum/viewtopic.php?t=4687920 is actually similar to the torrent file in this page, whereas the newest dictionary edition (2010)is THIS one with many more kanji and words (and of course pages)added. I've buyed it from Amazon here:

This:

is a kanji dictionary from Shogakukan for elementary grade.
-The 1989 version has got the basics kanji, known as the 1006 kyōiku kanji that elementary kids learn from school divided in 6 years. The focus on this dictionary is the reading(on, kun), number strokes and most of all how the character has been created (from ancient times to modern one) and a simple graphics will explain the process.
-The 2001 version of Shogakukan kanji dictionary for elementary school adds like 2000 more kanji, more words related to kanji and a better and revised graphic and explanation as well as many cultural reference notes here and there.

The modern version of 80's Gakken, 小学生の新レインボー漢字読み書き辞典, Shogakusei no shin rainbow kanji yomikaki jiten, the torrent that is present in this page, is this one here:
http://www.amazon.co.jp/%E5%B0%8F%E5%AD%A6%E7%94%9F%E3%81%AE%E6%96%B0%E3%83%AC%E3...8%BE%9E%E5%85%B8
So the name "Tadashiku kaku yomu shouchuugaku kanji" is totally FALSE.
The REAL name of this torrent is similar to the modern version of the file 小学生の新レインボー漢字読み書き辞典, Shogakusei no shin rainbow kanji yomikaki jiten.
What content has got this one? Well this is a bestselling dictionary for elementary school from over 40 years, but the content are really much simpler and the focus is on the 1006 kanji associated to images for a better and quicker memorization of strokes and concept at the root of one kanji.
So, the real image of the first edition of Gakken rainbow is this one:[url=]
