Japan eSIM prices: Airalo vs Holafly (23 October 2026)

Updated:

Before travelling to Japan we compared eSIM prices from two providers: Airalo (17 plans, cheapest $4) and Holafly (unlimited data from $3.90 per day), as shown on both sites on 23 October 2026.

If you need lots of data, the biggest fixed plan is 20 GB for 15 days at $24 ($1.20/GB). Airalo names the network in Japan as KDDI (5G) and Softbank (5G).

Before you buy

For a week in Japan, maps and messaging usually fit a small plan such as 3 GB for 7 days at $8; if you hotspot or upload a lot, the real choice is between the biggest fixed plan and unlimited data (Holafly 7 days at $27.50). Check your phone supports eSIM and is carrier-unlocked before buying.
