This is for traveling from Japan to Thailand. The data is the IEC list (as of June 2025). Some places or buildings may use other types, so treat it as a guide.
| Voltage | Frequency | Plug types | |
|---|---|---|---|
| Thailand | 220V | 50Hz | A, B, C, F |
| Japan (for comparison) | 100V | 50 / 60Hz | A, B |
Depends on socket: Thailand uses types A, B, C, F (per the IEC list). This includes type A, the same as Japan, but sockets differ by building. To fit types C, F sockets, use a plug adapter (C, F).
