Japan holds #8 on the headline ranking, against 7 others we score in G10. Every one of them shares Japan's band. Their split: 7 in 50–65. Sweden tops them at #6; Germany closes them at #51. Closest either side of Japan: Sweden at #6 and United Kingdom at #27. Mid-table is where the ranking moves most: a couple of points reshuffles several places. Without a week-earlier reading there is no direction to set against the table yet. Same seven dimensions, same sources, same day.

Rank is the position in the full cross-country ranking, not within G10. 7 of these 7 carry one. Composite scores are part of a subscription.

Questions about the Japan score

What does a score of 63.8 mean for Japan?

63.8/100, band 50–65: some of the discipline holds and some of it slips, which is what the middle looks like. That is 13.8 points above the 50 mid-point of the scale. Seven weighted dimensions produce the figure and no analyst adjusts it afterwards. Nothing in it is a forecast — it grades what Japan's central bank has already done, said and delivered.

How often is Japan's score updated?

Nightly, off that day's public releases; this page carries the 2026-09-08 run. There is no reading from seven days ago to set this one against. A 90-day trailing average damps single prints, so a weekly move past a couple of points is a real one. Tomorrow's run replaces the 2026-09-08 figure outright rather than revising it in place.

What is the 50–65 credibility band?

Five bands cut the scale — ≥ 80, 65–80, 50–65, 35–50, < 35 — and 50–65 is step 3. Japan clears its 50 floor by 13.8 and stops 1.2 short of 65. The step above is 65–80 and the step below is 35–50. Bands grade monetary behaviour, not default risk, so none of this is a credit rating.
