Toshiharu NOMOTO (The University of Tokyo), Koji DOZAKI (The Japan Atomic Power Company), Akihiro SAKASHITA (The Tokyo Electric Power Co., INC.) , Shinro HIRANO (The Kansai Electric Power Co., INC.), Tooru OTSUBO (TOSHIBA CORPORATION), Takashi ITO (Hitachi-GE Nuclear Energy, Ltd.), Jinichi MIYAGUCHI (Mitsubishi Heavy Industries, LTD.), Ichiro KOMURA (Japan Power Engineering and Inspection), Takayuki AOKI (Tohoku University), Mayu NAKAMURA and Nami TOHARA (Japan Society of Maintenology)

One year has passed since Electronic Journal of Advanced Maintenance (EJAM) was started on the website of Japan Society of Maintenology (JSM) May 25th, 2009. "New Technology" (NT) is one of the EJAM categories, and introduces widely advanced techniques developed or modified for maintenance. Twenty-two NT articles have been introduced on EJAM website so far as of May 25th, 2010. This report describes the concept of NT, general features of NT articles, actual performance and future wishes for NT.
