Highly recommended if travelling beyond the usual city destinations
Easy to connect, and good connection across Tokyo, Atami, Yamanakako and Nagoya. While it's not the cheapest option available, it's certainly NTT Docomo (some market as that but are not).

Easy to install and navigate through the app.
Good value.
It was helpful to receive instructions on how to set up my phone so I could move from my Primary Sim to Ubigi.
