There is not need supporting all bands for having coverage in the different types of networks. For example, if it does not support one band, could make you not to have 4G coverage in rural areas or having bad coverage inside buildings, but having it without problems in cities.

In this page we are going to show you the compatibility of Samsung Galaxy S21 5G with the mobile networks of Japan and with the telephony operators that provide service in Japan.

Keep in mind that to have a perfect coverage, the ideal thing is that the Samsung Galaxy S21 5G has all the frequencies for all networks, that are used in Japan, although if the Samsung Galaxy S21 5G lacks any of the frequency bands used, it does not mean that it does not work on that network, but coverage could be limited to certain areas.
