The eight papers were selected for the best paper award in 2021 to 2022 from Materials Transactions. Here, the awarded papers are briefly summarized as current trends in research of Materials Transactions. Among the eight best papers, four were specially selected for young scientists whose ages are 35 or below. An important trend in the year of 2021 is that three best papers are from a special issue with the title of "Materials Science on Hypermaterials", which is based on an ongoing national research project, Grant-in-Aid for Scientific Research on Innovative Areas.
