How to get a Sim card?

Kindly someone help me understand how to get a sim card if I don't own a credit card.

Option 1: Pay cash at the vending machine once you arrived at the airport.
Option 2: Buy at amazon in your country
Option 3: Go to electronica shop to buy a sim card

I would be good if you could be more specific what kind of sim card you want to buy, your arrival location.

Where now? already or living in Japan?

Prepaid SIM enough? if so, you can buy it by cash(JPY) at
int'l airports(vending machine or), major big terminal rail stns, Express-way bus terminals,
major electoric stores, convenience stores are mainly.

Hi Vinolin,

If I were you, I would get a SIM card before traveling to Japan. You know, just in case, to be prepared for your trip. Also, I see that you don't have a credit card. In my case, I don't like paying online with my credit card, so I always use Paypal for it. I bought my SIM card, per the recommendation of my sister in law, here: https://www.jrailpass.com/sim-card. They do accept Paypal, and for me, that was one of the main reasons why I decided to get my card on this site.

Hi, vinolin.

I'm a Japanese working in Tokyo for over a decade.
Let me help you some.

As justmyday said to you, those options will work fine.
I just continue that.

First, I'll add a list for justmyday's options 1 & 2 so that you can grab a bigger picture

Secondly, let me add an option.


Option 4: Rent a SIM card

Mostly, you can receive it at your designated places incl. airports & accomodations.
Mostly, they are refundable.
Mostly, you can rent it with a lower price.

I just put a list for rental SIM card plans to compare prices and other specs.
