The verdict
The 2026 ranking for Japan Pocket WiFi providers highlights Japan Wireless and Ninja WiFi as the top performers, excelling in speed, data offerings, and overall value.

Where the AIs disagreed
AI judges likely encountered the most significant disagreements in the mid-tier, particularly concerning providers ranked 4 through 7. Subtle differences in customer support quality, unique delivery options, or specific data caps between Global WiFi, Wi-Ho!, and Pupuru made precise differentiation challenging.

How Banzuke Works (METHODOLOGY)
The Banzuke editors have three AIs (Claude, GPT, and Gemini) each independently select a Top 10, then aggregate the results using the Borda count method (10 points for 1st down to 1 point for 10th) to compose this ranking.
Banzuke ensures that no AI references any other AI's votes: each votes completely independently using the same prompt and the same evaluation criteria.
Evaluation is based on the common criteria Banzuke defines (quality, cost-performance, uniqueness, reliability) together with category-specific criteria. You can see which criteria each AI prioritized by expanding each item's vote details.
