How we score Japan Wireless
Japan Wireless is graded with the same eight-dimension rubric as every other provider on eSIMBench — no hand-tuning, no exceptions. This page documents, dimension by dimension, where Japan Wireless's number actually comes from and what we have verified so far. Where a value is not yet real and sourced, we show "Pending" rather than guess. For the master weighting and our independence safeguards, see the site-wide methodology.
