Yesim eSIM Data Plans for Japan

Yesim offers unlimited data eSIM plans for Japan with validity periods ranging from 1 day to 30 days. Prices start at $8.08 USD for a 1‑day plan and go up to $63.48 USD for a 30‑day plan, all using 5G network coverage. The unlimited data is subject to a fair‑usage policy; normal speed may be throttled after heavy usage. Travellers who are concerned about potential speed restrictions should contact Yesim directly to confirm how the policy applies and the typical amount of data available at normal speed.

Yesim does not provide a Japan eSIM that includes a local phone number or SMS capability. The plans available from Yesim for Japan are data‑only, so you can use a high‑speed internet connection but cannot send or receive traditional SMS messages or make calls using a local number. Travelers can still use internet‑based messaging and calling apps such as WhatsApp, Telegram, or iMessage over the data connection.

Yesim provides eight individual plans that cover only Japan and 24 broader itineraries that include Japan. The single‑country plans start at about $8.08 USD for a 5 GB or less allocation and can rise to roughly $229.66 USD for a 365‑day unlimited package. The multi‑country bundles offer similar price and data ranges, with travelers able to choose either a daily data cap or a fixed data amount depending on the itinerary selected.
