I recently noticed this new book going on the market soon.  It seems to be similiar in approach to RTK.

The Kodansha Kanji Learner's Course is an innovative and highly effective system for learning and remembering kanji, or Sino-Japanese characters. The book contains 2,300 character entries, including all 2,136 Joyo Kanji ("regular-use kanji") plus 164 of the most useful non

Each kanji is accompanied by an explanation of how to remember its meaning(s) clearly and distinctly. These mnemonic explanations teach you to associate each kanji's graphical form with its unique range of meaning, often by "seeing" its meaning in the form of the kanji itself. An outstanding feature of the course is the special attention it gives to the challenge of learning each kanji in a differentiated way. This allows you to associate the meaning of each character with the features that distinguish it from graphically similar characters.

Another unique feature-and a significant breakthrough in kanji pedagogy-is the sequence in which the course introduces kanji. Most kanji dictionaries and textbooks arrange their entries in ways that do not address the needs of non-native learners, such as by traditional radical or by the grades in which the kanji are taught in Japanese schools. The Kodansha Kanji Learner's Course uses an original sequence that presents graphically related characters one after the other to help you give significance to their contrastive features as you learn them, and thereby avoid having to relearn them later. It also introduces the meaning and usage of each graphical element-each kanji building block-the first time it appears, thus enabling you to seamlessly and rapidly acquire new characters. In short, The Kodansha Kanji Learner's Course makes learning and remembering kanji easier than ever before.

This book fills an urgent need for a timesaving yet sophisticated kanji-learning system that can be used from beginning through advanced levels-an enjoyable, no-nonsense path to proficiency. It is intended for anyone serious about learning to read Japanese.
