What is Golden Week?
Golden Week (γ΄γΌγ«γγ³γ¦γ£γΌγ―) is Japan's longest holiday period, running from April 29 to May 6. It combines four national holidays and attracts millions of domestic and international travelers.
2026 Dates:
- April 29 (Wed) β Showa Day
- May 3 (Sun) β Constitution Memorial Day
- May 4 (Mon) β Greenery Day
- May 5 (Tue) β Children's Day
- May 6 (Wed) β Substitute Holiday
Many Japanese take the entire week off, making it one of the busiest travel periods of the year.
Why eSIM Matters More During Golden Week
Golden Week travel is different from regular tourism:
1. Crowded transport β Shinkansen and airports at capacity. You need real-time schedule updates
2. Restaurant queues β Use apps like Tabelog and Hot Pepper to check wait times and reserve
3. Last-minute changes β Flexible itinerary requires constant map/search access
4. Photo sharing β Cherry blossoms (late bloomers in Tohoku/Hokkaido) and festivals = heavy photo uploading
Data usage during Golden Week is typically 30-50% higher than normal tourism.
How Much Data Do You Need?
| Usage Level | Daily | 7-day GW | Best For |
