Italy to Japan plug adapter: plugs and voltage compared

No. ENIT (Italia.it) names Type C (round pins) for Italy. Japan's outlets take Type A plugs with two flat pins (JNTO), so bring a plug adapter to Type A. Japan runs on 100V and Italy on 220V.

What to pack in Italy for Japan

Round pins from Italy need a Type A adapter in Japan.

Round pins: a plug adapter to Type A. Source: ENIT, Italia.it.
Each device from Italy: read INPUT. 100-240V covers Japan's 100V; 220V alone needs a voltage converter (JNTO).
Italy: 50Hz. Tokyo: 50Hz. Osaka: 60Hz. A 50/60Hz label covers all three.

Flow chart for travellers from Italy: does the plug have two flat pins, and does INPUT include 100V? If not, bring a plug adapter or a voltage converter.

What official pages in Italy say

5 statements from ENIT (Italia.it) and ARERA (Italian energy regulator).

ENIT (Italia.it)Electricity is distributed everywhere with alternating current, 220V and a frequency of 50 Hz.Practical information

ENIT (Italia.it)In Italy, power sockets are regulated by Cei 23-50, all symmetrical and non-polarised, i.e. the plug can be inserted either way. You can find the C-type socket, with 2 or 3 symmetrical holes, or the L-type socket, with larger cables and prongs.Practical information

ENIT (Italia.it)The multistandard combines the two types and allows you to connect all types of Italian plugs and the German Shuko plug.Practical information

ARERA (Italian energy regulator)una tensione nominale di alimentazione di 220 Volt (monofase) o 380 Volt (trifase). Nella maggior parte dei casi le forniture domestiche sono a 220 Volt.Other useful information on the electricity bill

In English: a nominal supply voltage of 220 V (single-phase) or 380 V (three-phase). In most cases domestic supplies are at 220 V.

Frequently asked questions

Do I need a plug adapter in Japan from Italy?

No. ENIT (Italia.it) names Type C (round pins) for Italy. Japan's outlets take Type A plugs with two flat pins (JNTO), so bring a plug adapter to Type A.

Is Japan's voltage the same as Italy's?

No. Japan uses 100V (JNTO); Italy uses 220V, according to ARERA (Italian energy regulator).

Do I need a voltage converter in Japan from Italy?

Only for devices rated for 220V alone that are not dual-voltage (JNTO). A charger from Italy marked 100-240V needs none.
