Best eSIM Plans for Short Trips to Japan (3-7 Days)

Quick Guide: eSIM for 3-7 Day Trips

A weekend in Tokyo or a week hitting Tokyo-Kyoto-Osaka? You'll use 300-500 MB/day for Google Maps, restaurant lookups, and messaging. That's 1-3 GB total. Don't overpay for 30-day plans when you only need a week — short-term plans start under $5 and save you money. Pro tip: buy and install the eSIM the night before your flight. It activates on first use, so your days won't start counting until you land.
