MicroEsim does sell unlimited‑data eSIM plans for Japan. The plans start at $2.13 USD for a 1‑day 5G SoftBank/KDDI service and are available up to 20 days, with the longest unlimited option priced at about $46.76 USD for 20 days. All unlimited plans come with a “speed may be throttled” feature, meaning that the network may reduce the data rate after heavy use. Normal speed is typically 5Mbps for SoftBank/KDDI or 10Mbps for KDDI AU plans, but after a Fair Usage Policy threshold the speed can drop, and can also be limited by the plan’s stated capped speed. If you need to know the exact threshold or confirm whether throttling will affect your usage, it is advisable to contact MicroEsim directly for details on their Fair Usage Policy and actual data available at full speed.
MicroEsim does not provide a Japan eSIM plan that includes a phone number or SMS capability. Only data‑only eSIMs are available from this provider for Japan. Travelers can still use popular VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection to make calls and send messages without a local phone number.
MicroEsim offers 135 single‑country data plans and 97 multi‑country plans that can be used in Japan. The single‑country portfolio includes both fixed‑data packages, which grant a set amount of megabytes for the full validity period, and daily‑cap plans, which limit data usage on a day‑by‑day basis. Prices for all Japan‑compatible plans range from USD 0.81 to USD 165.24, data caps vary from 500 MB up to unlimited, and validity periods span from one to 60 days.
