Suitable for: 1. Long-haul travelers (9 days 8 nights or 10 days 9 nights) with extended stays: Perfect for 9-10 day trips with 5 days off for two weekends (e.g., Tokyo + Kansai dual-city tour, Kyushu panoramic tour, Shikoku in-depth road trip). Eliminates the hassle of buying two SIM cards: Most common Japanese SIM cards are 5 or 8 days, this 10-day card perfectly covers long trips without needing to switch cards mid-trip. 2. Budget-conscious and budget-conscious light/moderate internet users with ample average data allowance: 12GB for 10 days, averaging 1.2GB of high-speed data per day. For those who don't watch videos, this is a very generous "light luxury" data allowance. Highly competitive price: Compared to "10-day unlimited speed" cards, this card with a FUP (Fulfilled Per User) limit is much cheaper, offering excellent value. 3. Ideal for everyday travelers with hotel Wi-Fi: Suitable for travelers who only use Google Maps for navigation, LINE/WhatsApp for sending photos and voice messages, checking restaurant guides online, and making payments via PayPal during the day. Switch back to hotel: Once you get used to switching to the hotel's free Wi-Fi at night for watching shows and backing up photos, 12GB of high-speed data is more than enough during the day. 4. For novice independent travelers prioritizing "internet safety": Even if you accidentally use up the 12GB of high-speed data in the last few days of your trip, the reduced unlimited data speed will still ensure you can send LINE text messages, make voice calls, and even barely use Google Maps text navigation. You'll never be disconnected from the outside world in unfamiliar places.
