I have used SIM card rentals during my 1st and 2nd trip to Japan, and while the prices were reasonable, I didn't like having to pick them up at the airport post office and mailing them back just before I left Japan

You can purchase additional bandwidth as necessary for a reasonable price.

The initial price for the SIM card, SIM ejection tool, and 1 GB of data is reasonable

Definitely worth the price.

eConnect's prices were not the most competitive in some areas however with this card and the ease of use I feel that if you are going for the low data option they are the best choice

In my opinion, the price for top-ups are also reasonable

However, since I was unable to use it, I returned it and was promptly refunded the purchase price.

And the price was very competitive with buying in Japan or elsewhere

Too bad I
