eSIM plans in Japan: what to expect
Datadopt lists more than 4700 eSIM plans in Japan, sold by 30 different providers. Prices start at $0.59 (€0.52) for a small data bundle: that is the cheapest way in to stay connected the moment you land.
The cheapest 5 GB plan valid 30 days costs $2.63 (€2.31), which works out to $0.53/GB (€0.46/GB). Across the 3597 fixed-volume plans we track in Japan, the median price per GB is $1.63/GB (€1.44/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.
