Data Limits
How much data do you need?
Your data needs will vary depending on your individual usage and preferences. A Gen Z will typically use up to about 840 MB (just under 1 GB) watching TikTok for an hour at default quality. For those infinite scrollers, let’s take a look at how much data you will need to stream your videos at average to high quality:

On the other hand, for those millennial users who spend their data for messaging, keeping up to date with the world and browsing social media, this is the typical data usage per day for those activities:

So how does this help you decide which data plan you will need? After doing the math and averaging the data for your needs, the average data plan a tourist who streams videos, uses navigation apps, and messaging platforms like WhatsApp, would need is 10GB or higher. This gives you:
- A buffer for heavier days (video calls, high-resolution streaming, navigation)
- Flexibility for unexpected usage like translation apps, weather updates, or map reroutes
However, if you feel you spend slightly more time on YouTube, work calls or writing essays, here are our suggestions for specific needs:
- Frequent YouTube/TikTok? Go for 15–20 GB, especially if you stream in HD.
- Mostly messaging/maps/news? You could get by with 5–7 GB, but it’s tight.
- Wi-Fi access daily (hotels, cafés). You may only need 3–5 GB if you’re disciplined.
Battery Life
This is specific to the provider, so make sure you do your research prior to purchasing. Additionally, the purpose for which you use your data has a significant impact on battery life, particularly when browsing the web, using Google Maps, and posting on TikTok. Then the average life is expected to be 9-11 hours. Battery Life is also dependent on how much you remember to charge it! If you charge your device to full capacity, you can expect a full day of data from most providers.
Which provider is right for you?
Every Japanese Pocket WiFi provider will offer generic daily data plans, some starting at 1GB a day to 10GB a day. However, if you are opting for a Pocket WiFi router, it is more than likely due to the fact that you are a long-term visitor in Japan. Therefore, the monthly plans will be of more interest to you. These range from 1OOGBp/m/m to 300GB p/m. You may also see phrases like ‘unlimited’ or ‘capped plans,’ which can vary in meaning depending on the carrier’s policy.
Each phrase varies depending on the provider; they can either be:
- Truly Unlimited: Rare and more expensive, with no throttling.
- High-Cap Plans:g., 100GB/month or 3GB/day – enough for most travellers.
- Fair Usage Policies: Some “unlimited” plans reduce your speed temporarily after heavy usage (e.g., over 10GB in 3 days).
Many providers will also refrain from using these phrases and have their own policies. Providers like Mobal state that they offer plans with up to 300GB per Month, and if you use more than expected in a single month, your data does not stop. Your data never runs out—it simply slows down, so you’re always connected. If you’ll be in Japan for over a month, your data resets on the 1st of each month!
On the other hand, a provider will use these sales phrases: NINJA WiFi offers an Infinite Unlimited Plan, ideal for corporate travellers or professionals who need to stay connected at all times. While there’s no hard data cap, the plan includes a fair usage policy—meaning if your usage is especially high, speeds may be reduced during peak hours to ensure network stability for all users.
