The fourth First Stars meeting, "First Stars IV", is aimed at discussing star formation through cosmic time and the impacts of first stars on galaxy formation, first explosions, cosmic reionization, and formation of massive black holes. This meeting will be held partially as a memorial conference for Professor Hayashi (1920-2010), in honour of his invaluable contributions to the study of star formation and cosmology.

In the five day meeting, by summarizing the advances in the past comprehensively, future issues will be addressed from wide points of view. Young researchers and students are especially encouraged to attend.
