Considering the recent increasing demand for a rapid dissemination service of high-impact research results and findings, the Japanese Journal of Applied Physics (JJAP) has decided to give the letter section (JJAP Part 2) its own journal title, namely, Applied Physics Express (abbreviated as APEX). In accordance with this title change in the letter section, from January 2008 (Vol. 47), the present “JJAP Part 1” is going to be published as simply Japanese Journal of Applied Physics (JJAP). The JJAP and APEX are published by the Japan Society of Applied Physics (JSAP) through the Institute of Pure and Applied Physics (IPAP).

A number of important letter papers—which have helped shape the present information-oriented society—have been published in the JJAP since the launch of the letter section in 1980; some of the papers appear in the “Highlights from the JJAP letter section”. In particular, articles that have significant impacts on applied physics and/or technology and are worthy of immediate publication have been highlighted by introducing the Express Letters section in April 1998. APEX is the successor of the present JJAP Part 2, not only inheriting the long-standing international reputation of the JJAP Part 2 but also further promoting its strength in terms of high scientific quality and prompt publication.
