Getting a prepaid sim card in Japan can be quite simple, however, not many people will consider that as compared to a prepaid sim card and WiFi rental egg. WiFi egg can be shared with many people and sim card cost in Japan is slightly higher and does not guarantee good connectivity. I have used a few different prepaid sim card for my trip to Japan, and here is the compilation of it. There are many sim card available in Japan but the cost can be quite expensive and not very efficient, is good to compare and check on which type of sim card is suitable for you.
What type of device is suitable for you?
- 1 Person: Prepaid Sim Card
- 1~2 Person: Prepaid Sim Card
- 3~4 Person: Pocket-router
- More than 5: Pocket-router
**The above suggestion is for reference, it depends on the individual preference**
What kind of data plan should you choose for your trip?
4 Days or lesser: 500MB
5~ 7 Days: 1GB
7~14 Days: 3GB
14~30 Days: 5GB
30 ~60 Days: 10GB
**The above suggestion is for reference, it depends on the individual preference**
Things to note for prepaid sim card purchase:
- Japan sim card as of now still do not support voice call for short-term stayers
- They do have voice call sim card available but it cost a lot
- Your phone must be SIM LOCK Free, please check with the respective sim card supplier
- All of the devices used in Japan be it prepaid sim card or wifi router, there will be a fair usage policy for speed per day even though the company states unlimited data (Unlimited data does not mean unlimited speed). **Do read the detailed fine prints**

2 cents opinion:
The next best sim card to buy if you arrive Japan late and the collection counter from other service providers are not available (take note of the operating hours for collection at the service providers counters), this is another option to choose from. Cost wise this can be the cheaper choice among the 30 days usage plan for 1.5GB. As the cost of the sim card depends on each individual vendor, therefore, we will have to do a comparison for each shop makes the whole process a little troublesome.

2 cents opinion:
Get the sim card at the airport or in Japan, as the online purchase only have 2 choices, however, from Amazon the 2GB sim card cost the least among the others. The so-net was actually known for its great speed and stability as compared with other brands which might be the reason for the price to be slightly higher than the others,
Overall:
With so many telecommunication service provider to choose from, personally, it still comes down to your preference to see which plan suits your need and budget. For me, I will choose a plan with 1.2GB ~2.4 GB, it’s good enough for a 2 weeks trip, if you love to upload photos and video to your social media. Otherwise, for the speed most of the service provider are standard and once you hit a certain usage or at an area where a lot of people are using it the speed will start to slow down. Do note that sometimes when you are on a train going through a tunnel there might not be connection available.
