What was Japan's April wholesale inflation rate, and how did it compare to expectations and the previous month's figure?

Japan's April wholesale inflation rate, as measured by the corporate goods price index (CGPI), rose 4.9% year-on-year, significantly exceeding the median market forecast of 3.0% and accelerating sharply from the revised 2.9% gain in March.

What key factor is cited in the news as driving the surge in Japan's April wholesale prices, and what supporting data is provided?

The news attributes the spike in April wholesale prices to 'the Iran war-induced spike in oil costs', which contributed to rising import costs; this is supported by the yen-based import price index surging 17.5% year-on-year in April, following a revised 8.0% gain in March.
