 note = {In June 1994, the National Institute of Radiological Sciences (NIRS) initiated heavy particle radiotherapy using carbon ion beams obtained from the Heavy Ion Medical Accelerator in Chiba (HIMAC), which was built as a part of the nation’s “Overall ten-year anti-cancer strategy in Japan,” which started in 1984. The construction was completed at the end of 1993, and the facility was opened for carbon ion radiotherapy (C-ion RT) the following year. Since then, the HIMAC has served as a multipurpose, shared facility that is jointly used for cancer therapy and fundamental particle beam studies by Japanese and foreign researchers. In 2010, a new treatment research building with three rooms was built to use beam lines extending from the HIMAC (Fig. 1). The new building was designed to be able to administer adaptive charged particle therapy with pencil beam scanning, as well as to allow a compact rotating gantry to be developed. Treatment with the scanning method started in 2011, and its indications have since been expanded to many types of tumors. 1)
 
C-ion RT has been applied for various types of malignancies at the NIRS.2),3),4) It was approved by the Ministry of Health, Welfare and Labor as a “Highly Advanced Medical Technology” in 2003. This means that C-ion RT has achieved a solid place in general practice based on the clinical experiences with C-ion RT at the NIRS.},
