In April 2006, Active Index Investing was published in Japanese by Toyo Keizai. This translation involved a three way collaborative effort by Professor Yukihiro Asano of Yokahuna National University, the Quantitative Investment Management Group of Sumitomo Trust, Ltd, and Northern Trust Global Investments.

As Japanese investors' become more sophisticated in their investment approach, Active Index Investing aims to provide a comprehensive review of the theories, products and strategies that have enabled investors to benefit from the 'indexing revolution' that contiues to gain momentum around the world.  And this website aims to supplement the book's 31 chapters with updated data, additional content and sidebars, and an opportunity for your feedback.  I hope you find both the book and it's E-ppendix informative and useful.
