Japan Stablecoin Payment Monitor: weekly change feed for stablecoin payment services in Japan — new launches, pilots, partnerships, fee changes, supported assets and chains, and closures. Each event is dated, categorized and tied to an official source URL. Pass changedSince=YYYY-MM-DD (your last run date) to fetch only new events; an empty changes list explicitly means no change. Without changedSince you get the full dated history back to late 2025.

Peak day 2026-08-23: 8 payments. Last indexed day 2026-09-04: 2. Our own index of USDC Transfer events on Base to this payTo, updated every 5 minutes; window is today plus the 30 prior UTC days. Base USDC only — a seller settling elsewhere reads as quiet here. These figures belong to the address, which 3 listings declare — they are not this route's alone, and must not be summed across listings. Methodology.
