Our editorial line
A link to a partner is never a forced recommendation: we judge every option on its own merits, partner or not.
We never publish an article without a byline: every piece links back to its author's page.
Sakura Tanaka — About this byline: Sakura is a Japan travel writer. At Japan eSIM she compares NTT Docomo, SoftBank and au plans for visitors exploring Tokyo, Kyoto and beyond.
Each article shows its publication date and is updated whenever something it covers changes: a price, a rule, a practice. If we can no longer keep it current, we remove it instead of leaving it outdated online.

This site focuses on eSIM data plans for international travel, with practical comparisons across providers like Airalo, Ubigi, and Journey, and country-specific guides ranging from Japan (arrival cards, Osaka coverage, staying connected during earthquakes) to Argentina, Brazil, and Turkmenistan. It does not cover general travel planning — itineraries, hotels, or sightseeing — since the focus stays strictly on data connectivity and discount codes rather than trip planning. Topics are chosen around concrete traveler questions that come up before and during a trip: which eSIM works in a specific country, how to activate it, and what to do when local networks are disrupted.
This choice is deliberate: better to cover one subject thoroughly than ten superficially. Content outside our field does not belong here, no matter how popular.
This site totals 73 published articles, at a current pace close to 24.3 per month. We are not chasing volume: every article is checked before going live, which naturally caps the pace. This site's activity started on June 16, 2026.
