Since 2014, research groups from Japan, Taiwan, and New Zealand have been collaborating to share research ideas and expertise about topics relevant to the development of national seismic hazard models (NSHMs) in each region. The trilateral collaboration is centered on a series of workshops designed to bring the researchers together. So far, three such meetings have been held: a kick‐off workshop in Taiwan in May 2014, a second workshop in Japan in August 2015, and a third workshop in New Zealand in November 2015. A fourth workshop is planned for late 2016. In this focus section on the joint Japan–Taiwan–New Zealand NSHM, we have collected eight papers that highlight some of the ongoing research that specifically targets improvements in the respective NSHMs.
