MicroEsim eSIM Data Plans for Japan

MicroEsim offers several unlimited‑data eSIM plans for Japan. The plans range from 1 day to 20 days, with prices starting at $2.24 USD for a 1‑day plan and going up to about $61.73 USD for a 19‑day plan. Each unlimited plan states that normal 4G, 5G, or LTE speeds may be throttled after heavy usage under a Fair Usage Policy, so data usage at the full advertised speed is not guaranteed. Travelers who want confirmation of the speed threshold or details about the throttling policy should contact MicroEsim directly.

MicroEsim does not provide a Japan eSIM plan that includes a phone number or SMS capability. Their Japan offerings are limited to data‑only plans. For voice and messaging, travelers can use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection.

MicroEsim provides 127 single‑country data plans and 97 multi‑country plans that include Japan, covering a wide variety of needs. For travelers who prefer a fixed amount of data, 118 plans offer a set data cap that can range from 500 MB up to unlimited, while 106 plans give a daily data allowance that can be used on a day‑by‑day basis. Across the board the price range for Japan‑specific coverage varies from about $0.85 to $165.24, and the data cap ranges from a small 500 MB bundle to unlimited data for longer stays.
