eSIM plans in Japan: what to expect
Datadopt lists more than 6000 eSIM plans in Japan, sold by 116 different providers. Prices start at $0.35 (€0.31) for a plan of 1 GB or more: that is the cheapest way in to stay connected the moment you land.
The cheapest 5 GB plan valid 30 days costs $2.61 (€2.33), which works out to $0.52/GB (€0.47/GB). Across the 4234 fixed-volume plans we track in Japan, the median price per GB is $1.54/GB (€1.37/GB). For reference, the worldwide average price of 1 GB of mobile data is $2.59/GB.
For a short stay, a few gigabytes valid 7 days are usually enough. For a longer trip, aim for 5 to 10 GB over 30 days, or consider an unlimited plan or a daily-quota plan: in that case compare the price per day rather than the total price.
