Powerful earthquakes that hit Kumamoto Prefecture in April caused damage worth ¥3.8 trillion, the local government has confirmed in its first estimate of the economic impact on the prefecture.

Homes suffered the worst damage at about ¥2 trillion, with approximately 170,000 houses affected including around 8,000 that were completely destroyed.

A magnitude-6.5 quake hit the prefecture on April 14, followed by a 7.3-magnitude quake two days later.

Damage to the business sector, including factories and hotels, was estimated at ¥820 billion and damage to roads, bridges and other public infrastructure at ¥268.5 billion, the government said Wednesday.

A total of ¥93.6 billion in damage was logged for cultural property, ¥148.7 billion for the agricultural sector and ¥90 billion for waste processing facilities.

In May, the central government estimated the damage in Kumamoto at around ¥1.8 trillion to ¥3.8 trillion.

The Hokkaido government said the same day that four powerful typhoons and an extratropical depression downgraded from a typhoon that hit the island in August caused ¥278.6 billion of damage, with flood damage totaling ¥66.1 billion.

Damage to the agricultural sector reached ¥54.2 billion, with 38,927 square meters of farmland used for growing onions and potatoes spoiled, while damage to the fisheries industry was estimated at ¥7.4 billion and the forestry sector at ¥6 billion.

The local government plans to compile its largest supplementary budget of ¥65 billion to rebuild infrastructure and other facilities.
