What this guide covers
- The voltage and plug types in Italy
- Whether you need a plug adapter
- Whether you can use electrical products from Japan
This is for traveling from Japan to Italy. The data is the IEC list (as of June 2025). Some places or buildings may use other types, so treat it as a guide.
1. Voltage, frequency and plug types
| Voltage | Frequency | Plug types | |
|---|---|---|---|
| Italy | 230V | 50Hz | C, F, L |
| Japan (for comparison) | 100V | 50 / 60Hz | A, B |

2. Plug adapter
Bring an adapter: Italy uses types C, F, L (per the IEC list). The list does not include Japan's type A → bring a plug adapter (C, F, L).

3. Electrical products from Japan
| "INPUT" on the product | Result |
|---|---|
| INPUT 100-240V | Voltage: Italy uses 230V. Within the label (100–240V) → no transformer needed |
| INPUT 100V only | Voltage: Italy uses 230V. Outside the label (100V) → do not use it as is. Use a product that supports Italy's voltage, or use a transformer (check the transformer's manual for which products and wattage it supports) |
Check the "INPUT" label on the charger, AC adapter or the product itself. For hair dryers and irons, see Taking a hair dryer or hair iron abroad; for plug shapes, see How to tell plug types A to N apart.
