I used this one on the recommendation of a friend. Worked fine. The WI-FI made sense to me as I was in Starbucks in alot. Thumbs up!
Only review I found was:

Wirelessgate Prepaid SIM


Wi-fi provider Wirelessgate offers a prepaid smartphone SIM card for overseas visitors to Japan. The cards offer connection to NTT Docomo’s LTE and 3G networks, as well as the use of 40,000+ wi-fi hotspots nationwide. The available options are: 1 GB of data transmission over a 14-day period, 2 GB over 30 days, and 3 GB over 60 days.

The cards also come in three sizes: standard, micro, and nano. You can adjust your settings, check how much data headroom you have left, search for wi-fi spots and take advantage of automatic wi-fi spot login using the Wirelessgate app, a free download from Google Play and the Apple App Store.

These cards are only available at Yodobashi Camera Stores (and Yodobashi Camera Online Store), priced at ¥2,950 for 1 GB, ¥3,590 for 2 GB, and ¥3,980 for 3 GB (all including tax). Users who reach their data-transmission limit can purchase an extra gigabyte to be used over a 14-day period, priced at ¥1,000 (including tax).
