“For Tokyo, I checked charger INPUT voltage and supported charging protocol on the phone wall charger before deciding whether an adapter was enough.”

Will my Smartphone power setup work in Tokyo?
For Tokyo, verify the exact smartphone equipment instead of relying on a country-level assumption. For a Smartphone, the item connected to wall power is the phone wall charger. Tokyo is listed at 100 V / 50 Hz, 60 Hz; read the exact equipment label for charger INPUT voltage and supported charging protocol before connecting it.
Equipment designed only for 220–240 V may not be suitable for this lower-voltage supply. Plug shape alone does not settle that question for a Smartphone. Across different accommodations in Tokyo, a tested smartphone power setup is easier to repeat.
Tokyo power: A · B · 100 V · 50 Hz, 60 Hz
See the Japan power plug guide →Do I need a plug adapter for a Smartphone in Tokyo?
The A · B outlet family answers plug fit for a smartphone, not whether it accepts 100 V. Tokyo uses A · B. If the plug on the phone wall charger does not match, a correctly rated plug adapter can solve the physical connection only; it does not change 100 V.
EPICKA Universal Travel Adapter — one option to compare for Smartphone travel in Tokyo
Check charger INPUT voltage and supported charging protocol first. This product should be considered only when it fits the exact smartphone setup; a plug adapter never changes Tokyo’s 100 V supply.

A hotel-room workaround in Tokyo should not replace checking the exact power setup before departure. For this Smartphone, also verify USB-C cable rating and fast-charge support. A replacement cable, charger or power supply should match the manufacturer’s electrical requirements, not merely fit the visible connector.
Should I use a voltage converter for a Smartphone in Tokyo?
Testing the complete smartphone setup before Tokyo keeps the travel-power kit simpler. When the phone wall charger already accepts 100 V, a voltage converter normally adds no benefit. Focus on a secure A · B connection and the exact power or charging requirements.
A practical Smartphone setup for Tokyo
Once the exact power setup is confirmed for Tokyo, extra conversion hardware is easier to avoid. For travel in Tokyo, Carry one verified wall charger plus a separate power bank for transit. Test the complete smartphone setup before departure and keep the official instructions available.
