What network will my Japan eSIM use?

Japan eSIMs for tourists typically connect to one or more of the major Japanese networks: NTT Docomo, KDDI au, or SoftBank. These carriers provide extensive 4G LTE coverage and growing 5G service in cities, which is ideal for maps, messaging, social media, and streaming while you travel. The exact network used depends on the specific eSIM plan you purchase, so check the product details before you buy.
