23rd Shinjuku City Half Marathon and Ward Residents’ Health Marathon 2026

Overview

The 23rd Shinjuku City Half Marathon and Ward Residents’ Health Marathon, held on Sunday, January 25, 2026, is a vibrant running event in Shinjuku Ward, Tokyo, welcoming runners of all ages and abilities. Taking place rain or shine, this event features a variety of races: a Japan Association of Athletics Federations (JAAF)-approved Half Marathon (6,500 participants), a 10K through the outer gardens of Meiji Jingu Shrine (3,000 participants), 3K, 2K, and 1K races for students (1,800 total), a Family Run (1,000 pairs), a Fun Run 5K and Relay (500 total), a Special Run (200m, 100 participants), and a “Chick” race for preschoolers (400 pairs). The main venue is the iconic National Stadium, with the Half Marathon route passing Shinjuku Station’s east exit, Kagurazaka, and Yasukuni Dori. Part of the 10th Japan ID Half Marathon Championships for athletes with intellectual disabilities, this event is inclusive and community-focused. With applications open from September 7 to October 31, 2025, and first-come, first-served entry for many races, early registration through Jasumo Tickets is critical due to high demand (X posts note “huge excitement for Shinjuku’s iconic course”).

Why Attend

• Unique Program: Diverse races from a JAAF-approved Half Marathon to family-friendly and inclusive events like the Chick and Special Runs, appealing to runners and families.
• Iconic Course: The Half Marathon runs through Shinjuku’s vibrant streets, including Kagurazaka and Yasukuni Dori, with the 10K weaving through Meiji Jingu’s scenic gardens.
• Premier Venue: National Stadium (10-1 Kasumigaoka-machi, Shinjuku-ku) offers a world-class start/finish point, praised on X for its “electric atmosphere.”
• Tourist-Friendly: Located near Meiji Jingu Shrine (10-min walk) and Shinjuku Gyoen National Garden (15-min walk), perfect for combining with sightseeing.
• Inclusive Options: Free entry for preschoolers (Chick Run) and accessible ID Divisions for athletes with intellectual disabilities, with 100 spots each for entry sponsorship and hometown tax donations.
• High Demand: Limited capacity (e.g., 6,500 for Half Marathon, 3,000 for 10K) and first-come, first-served entry for many races signal a sell-out risk.

Disclaimer

Jasumo offers a facilitation service for foreign tourists and non-Japanese residents in Japan, helping them access and apply for tickets to various events, including but not limited to sports, festivals, and cultural activities. We are not a reseller of tickets, nor do we sell tickets directly. Our role is to support international customers by guiding them through the official ticket booking process, ensuring they can secure their tickets through recognized platforms and authorized providers.

As a business based in Japan with a bilingual staff and a deep understanding of the challenges faced by non-Japanese visitors, we address common bottlenecks such as:

• Language Barriers: Navigating Japan’s primarily Japanese-language ticketing systems can be challenging for foreign tourists. Jasumo provides bilingual support to bridge this gap and ensure a smooth booking experience.
• Access to Japanese-Only Platforms: Many events in Japan require local knowledge to navigate and access, and often these platforms do not offer international payment options or are difficult to use for non-Japanese speakers. We facilitate the booking process by providing guidance and helping with international payment methods where applicable.
• Limited Availability & Complex Registration: Events in Japan often have limited capacity, and understanding the timing and process for securing tickets can be confusing for international visitors. Jasumo helps you manage deadlines and requirements, giving you the best chance of securing your entry.

Due to high demand for the 23rd Shinjuku City Half Marathon and Ward Residents’ Health Marathon 2026, with applications closing October 31, 2025, and limited capacity (e.g., 6,500 for Half Marathon, 3,000 for 10K), availability is not guaranteed. Refunds will only be issued if entries cannot be secured through official channels or in case of cancellation. We strongly recommend contacting Jasumo Tickets by September 7, 2025, for Half Marathon first registration or by October 31, 2025, for all races to secure entry at official prices.
