In a blow to Japanese Prime Minister Shinzo Abe ahead of the Senate next summer, Japan's economy fell for the first time in more than six years by 0.9 percent from February to March, according to the Japanese cabinet.
Which led statisticians to reduce their assessment of Japan's economy from "weak" to "deteriorating" - the lowest level in their assessments.
The government last used the lowest grade to describe the domestic economy in January 2013.
In the same vein, weakness in the economy's performance in March was driven by a drop in industrial production and slower shipments of consumer goods and investment goods in Tokyo.
The decline in the economic conditions index illustrates the growing side effects of the Sino-US trade war, with Japan severely hit in recent months as its exports to major Asian markets slow.
The decline in Japan's economic performance came ahead of the Senate elections next summer and the start date of Abe's decision to increase the consumption tax from 8 to 10 percent this fall.
