Chief cabinet secretary Yoshihide Suga explained the assets of an additional 19 entities and people would be suspended.
Over 210 businesses and individuals from countries such as China and Russia will then be targeted.
Firms on the blacklist contain banks, coal and minerals dealers, and transportation companies.
The growing of sanctions comes before a meeting of the UN Security Council to be held on Friday.
Japan said it’s facing a “pressing hazard hidden before” later North Korea fired an intercontinental ballistic missile (ICBM) throughout its land in September.
“North Korea established an ICBM ballistic Missile that landed in our exclusive economic zone and proceeds to replicate provocative commentaries”, Mr Suga told reporters on Friday.
Mr Suga said it’d freeze more resources to “further growth stress” on Pyongyang.
Japan already imposes strict limitations on North Korea, such as a blanket ban on commerce and port calls.
South Korea and the US also impose unilateral sanctions on North Korea, along with sanctions imposed by the UN.
The UN Security Council meeting on Friday is geared toward finding peaceful ways to pressure North Korea to stop its nuclear and ballistic missile evaluations and denuclearize the Korean Peninsula.
