BambooSIM eSIM Data Plans for Japan

Yes, BambooSIM sells unlimited data eSIM plans for Japan. The plans are available in 3‑, 5‑, 7‑, 10‑, 15‑, and 20‑day periods, with prices ranging from $8.95 for a 3‑day 10 Mbps plan to $57.98 for a 20‑day plan. All unlimited options are delivered over 5G and allow tethering; normal speed may be capped at the stated rate, and speeds may be reduced after heavy usage in accordance with a Fair Usage Policy. Travelers who need confirmation of speed limits or wish to discuss the typical amount of data that remains available at full speed should contact BambooSIM directly.

BambooSIM does not provide eSIM plans for Japan that include a phone number or SMS capability. The company only offers data‑only plans. Travelers who need voice or messaging services can use VoIP applications such as WhatsApp, Telegram or iMessage over the data connection, but some destinations may block certain apps, so users should confirm that the services they rely on are accessible in Japan before purchasing.

BambooSIM offers 38 single‑country data plans and 26 multi‑country plans that cover Japan.
The single‑country plans range in price from about $0.99 to $57.98 and include data caps from 1 GB up to unlimited, with validity periods between 3 and 30 days.
Multi‑country plans also span the same price and data ranges; they can be used across several countries while still providing coverage in Japan.
