99% of gas stations in Japan are only available in Japanese.
There are two types of gas stations: "Self service" and "Full service”.
"Self service"
The word "セルフ" is written in Japanese on the signboard of the gas station.
This Japanese word may be confusing for you, but if there is no staff inside the gas station or if other drivers are refueling themselves, it is " Self service".
Self-service gas stations usually have an LCD panel next to the fueling hose.
