Japan to Costa Rica: Complete Plug & Adapter Guide (2026) No Adapter Needed
Whether it's a business trip or a vacation, traveling from Japan to Costa Rica requires a quick check on power compatibility. The last thing you want is to arrive and discover your charger doesn't fit the outlets.
Good news: Japan and Costa Rica share compatible plug types (Type A and B). Your existing plugs should fit directly into Costa Rica's outlets without any adapter needed.
On the voltage front, Japan (100V, 50Hz/60Hz) and Costa Rica (120V, 60Hz) are very similar. You shouldn't need a voltage converter for your electronics.
A universal travel adapter with multiple plug configurations is a smart investment if you travel frequently. For Costa Rica specifically, look for one that supports Type A/B outlets. USB charging ports built into the adapter are a nice bonus.
