GIGAGO eSIM Data Plans for Japan

GIGAGO does not offer an unlimited data eSIM plan for Japan. All available plans have a fixed data cap.

GIGAGO’s fixed data options include a 50 GB plan valid for 5 days priced at $67.50 USD, a 50 GB plan valid for 30 days priced at $77.50 USD, and a 20 GB plan valid for 5 days priced at $27.50 USD. Selecting a fixed data plan can be more cost‑effective for most travelers unless a very heavy data usage is required.

GIGAGO does not provide any Japan eSIM that includes a phone number or SMS capability. Only data‑only plans are offered for Japan, so travelers cannot receive inbound calls or standard text messages on the local network.

Because a phone number is not assigned, travelers can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection for voice and messaging needs. These solutions work without requiring a local Japanese phone number.

GIGAGO currently offers 28 single-country data plans specifically for Japan, alongside 42 plans that provide multi-country coverage including Japan. These plans range in price from approximately $7.50 to $94.50 and offer data allowances from 500MB up to 50GB. Of these plans, 36 feature a daily data cap, while 34 provide a fixed data allowance for the plan's duration.
