I had asked airsim about the difference between Docomo and SoftBank package. This is their reply below. After much thought, i will be getting Docomo for my wife and SoftBank for myself, in case signals are weak in some areas for one carrier but not the other we are still covered.
==========================
For Japan Docomo it comes with data limit (eg: 1/2/3/5GB) and Japan Softbank comes with unlimited data with fair usage policy.
The difference between the two Softbank 4G data has dailyÂ*500MBÂ*data at 4G speed before the internet access speed slow down and 4G MAX hasÂ*1GBÂ*data. Both package at slower speed remained unlimited data for accessing to WhatsApp, Google App or other App that required less internet bandwidth. The internet speed will be reset back to 4G speed after 0000hrs Singapore time the next day.
For recommendation to casual visitors using GPS/maps and WhatsApps is to purchase the Softbank Max 4G data.
