Suitable for: 1. Standard 6-day, 5-night vacationers or "double weekend" special travelers: Fixed 6-day validity period. Suitable for: Working people planning a 6-day, 5-night trip to Japan, or those who use "taking leave from Monday to Thursday + the two weekends before and after" to create a 6-day long vacation. This number of days perfectly covers the entire trip, and the network is uninterrupted from arrival to the day of return. 2. "In-depth tour of the whole country" or self-driving group who can freely switch between four networks: Most Japanese SIM cards on the market only support a single network. This card combines Docomo (widest base station coverage), Softbank (ultra-fast in urban areas), KDDI (stable in Au) and Rakuten (new network) [5.1]. Suitable for: Self-driving/inter-regional travelers: Driving from Tokyo all the way to Mount Fuji, Hakone, or traversing the Kanto region. Because it supports all four networks, the phone will automatically find the operator with the strongest signal in mountainous areas, tunnels, and highways, and the navigation will never be interrupted. 3. **In-depth travel to remote areas:** Travelers exploring hidden gems in Hokkaido, rural Kyushu, Shikoku, or outlying islands. With four network complementarities, there are virtually no dead zones. 4. **Precise match for heavy internet users who reject data throttling:** Clearly marked as 【Full 5G unrestricted speed】 and unlimited data. Suitable for: Heavy entertainment users: Those who need to watch 4K HD videos, browse TikTok/Douyin, play online mobile games, or watch high-bitrate live streams during breaks in their busy schedules or after returning to their hotels at night. Also suitable for: Game/anime fans: High-end anime and manga enthusiasts who need to upload and download images frequently or browse social media in real-time at Akihabara or anime conventions. 5. **Precise match for mobile office workers (digital nomads) and Vlog creators:** Truly unlimited, extremely high-speed, and with no speed reduction for 6 days. Suitable for: Self-media bloggers: Creators who update their Japan travel vlogs in real-time on Xiaohongshu, YouTube, and Instagram, or live stream their travel or shopping experiences in Shinsaibashi or Ginza. Business travelers: White-collar workers who need to connect their computers to their mobile hotspots anytime, anywhere to handle large work attachments or conduct high-frame-rate remote video conferences. 5. A perfect match for groups traveling together and sharing a hotspot: Unlimited 5G data with no data cap or speed limit. Suitable for: 2-3 people traveling together who plan to buy only one SIM card and have one phone continuously share the WiFi hotspot for the whole group.
