I bought the Wi-Ho datasim at the Narita airport for the prices mentioned above. As probably with every provider the setup process takes a while, but eventually you can be confident it will work. The leafletyou get with it is small but it is easy to understand. Topping up works like a breeze; the data is immediately available.

The coverage is excellent and I always had good reception on my TP-link mifi M7350, even though it has not all the bands NTTdocomo uses.

I also had a small package of data on my regular contract which I use in a Galaxy S8 unlocked 'world version' sold in Europe; since this phone has a very wide range of bands it can work on I always had good reception on both NTTdocomo and Softbank. One other person in our group used a Galaxy A5, which is not sold in Japan; she switched between 4G and 3G but ultimately was able to have a workable data connection for things like finding your way with Google Maps. So in the end probably you will be able to connect with your European mobile device

It appears as if a lot of the prepaid data offerings I found on some websites have disappeared, for example the Japan Travel Sim is almost nowhere to be found. Also a lot of the offerings have a daily limit of data which is very unpractical. This Wi-Ho offering has an amount of data that you use till it's finished and you can top-up if you want to.

The 'free wifi' you can find in streets, stations and airports is always difficult to log in to and often limited in speed, time or amount of data. the only reliable wifi is in hotels and cafés. I would stongly advise to invest in mobile data, since you will often find yourself out of range of useable wifi and most tourists in Japan will really need mobile access to find your way, check trains, opening hours etcetera.
