In Japan, which has a large geriatric population, surgical indications for elderly patients have expanded through improvements in medical treatment. In an elderly patient, many complications can occur in the perioperative period including respiratory or cardiovascular organ compromise, falls, sarcopenia, and worsening of cognitive function. The ERAS protocol recommends prehabilitation as an environmental rationalization measure to improve surgical outcomes. Prehabilitation involves three interventions：an exercise regimen, psychological support, and nutritional support. This prehabilitation regimen has been shown to reduce postoperative pain and length of stay and improve physical fitness as compared to standard care. Unfortunately, Japan has yet to implement similar preoperative care due to a lack of preoperative preparation and support from insurance systems.
