Bringing Healthcare Closer to Home: The Shinjuku Community Festival

Bringing Healthcare Closer to Home: The 44th Greater Shinjuku Festival



The Greater Shinjuku Festival, held annually, is a vibrant event where local governments, organizations, and businesses collaborate to promote community engagement. This year’s event theme, “Experience Shinjuku's Tradition and Cutting-Edge Innovations!”, highlights various booths from local companies and healthcare groups that offer engaging health-related experiences and fun activities for families.

A standout feature of this year’s festival is the collaborative booth between the Shinjuku Pharmacy Association and innovative healthcare venture Kokoromil. Attendees will have the opportunity to experience Kokoromil's Home Heart Dock Pro, which allows for hospital-level electrocardiogram (ECG) tests to be conducted from the comfort of one’s home.

A Closer Look at Heart Health


Every day in Japan, a significant number of individuals lose their lives to sudden cardiac events. Approximately 91,000 cases occur annually, which equates to about 250 people a day, or one person every six minutes. Note: This event does not substitute for professional medical diagnoses.

Kokoromil's Home Heart Dock® series stands out with a remarkable performance that detects arrhythmias at a rate of 36%, compared to just 10% during regular health checks. This technology also monitors sleep quality, sleep apnea, and signs of stress, specifically targeting sudden death risks that traditional health screenings often overlook. The collaboration between local pharmacies and private enterprises, aimed at enhancing community health, serves as an exemplary model of regional medical collaboration.

Addressing the Urban Aging Challenge in Shinjuku


In Tokyo, the aging population is becoming increasingly significant, with projections indicating that by 2025, 23% of the overall population will be elderly. This figure is expected to climb to 25.4% by 2035, marking a reality where one in four citizens is of retirement age. In Shinjuku, the elderly population rate is projected to rise from 19.9% to 21.8%, leading to scenarios where single elderly individuals outnumber couple households, paving the way to a “single elderly society.”

The number of people requiring nursing care or assistance in Tokyo is also climbing, with higher rates than the national average. This urban aging trend brings about significant challenges, including increased burdens on healthcare facilities and a chronic shortage of healthcare personnel. The prevalence of unnoticed health issues exacerbates the widening health disparity.

Heart conditions and sudden death often go undetected during routine check-ups, which raises the critical need for systems that can identify issues before they manifest as symptoms.

Supporting Urban Dwellers' Health Through Local Pharmacies and Medical Technology


In today’s society, local pharmacies play a critical role as gateways to healthcare, connecting hospitals with homes. Shinjuku’s diverse population, where many busy professionals and single elderly individuals reside, faces challenges such as inadequate access to medical facilities and a lack of motivation to undergo necessary testing.

Heart problems notably often remain unnoticed as they may not exhibit symptoms until it is too late. Unlike cancers, which are often perceived as unavoidable, heart conditions can fall under the radar, leading to severe consequences.

At the Fureai Festival, event participants will have the chance to experience an ECG measurement first-hand, with pharmacists available to offer health support, lifestyle improvement advice, and exclusive campaigns for attendees. This interaction allows visitors to engage with healthcare professionals and visualize their health risks in real time. Note: This experience focuses on increasing awareness rather than providing a diagnostic outcome.
