[2025 Update] Where to Get a Flu Shot in Japan–A Guide for Travelers

Introduction

Flu season in Japan typically begins in October and peaks between December and February. For international travelers—especially those arriving from tropical or warmer climates—getting a flu shot before or during your trip can reduce the risk of illness and avoid disruption to your travel plans.

Japan's 2025 Flu Season: What Travelers Need to Know

According to the some Japanese articles, as of late October 2025, Japan is already experiencing a significant rise in influenza cases—much earlier than usual. Health officials have issued alerts in Tokyo and the greater metropolitan area, where patient numbers have already exceeded the warning threshold. The outbreak is expanding rapidly, and early flu vaccination is strongly recommended, especially for travelers planning to visit Japan between November and February.

Key Trends in 2025

This year’s flu season shows several critical patterns:

• Earlier-than-usual outbreak: The flu season began about a month earlier than average, increasing the likelihood of a longer and more intense peak lasting into January.
• Regional surges: Tokyo, surrounding prefectures, and Okinawa are seeing the highest spikes, though cases are rising nationwide.
• Virus strains: Influenza A (including both H3N2 and H1N1) is currently dominant, with Influenza B expected to emerge later in the season.
• School closures increasing: More cases of class suspensions and school closures are being reported across the country, prompting heightened regional precautions.

Why This Matters for Travelers

For international visitors, especially those with children, chronic conditions, or plans to stay in Japan for several weeks, getting a flu shot is more important than ever. The unique strains circulating in Japan, combined with crowded public transport and winter weather, increase exposure risk.

Cost & Timing (2025 Info)

Flu shot costs for non‑insured travelers vary widely, typically in the ¥4,000–¥9,000 range depending on the clinic and age group. Some insurance subsidies apply only to Japanese residents (e.g., up to ¥2,000 subsidy for insured persons in 2025).(Refrrance: https://www.jerakenpo.or.jp/eng/member/health/flu)Best timing: late October to early November is ideal; however, vaccination later in the season still offers benefit.
