Seems he deserved it.

Japan executed its first foreigner-born prisoner in a decade Thursday — a Chinese man accused in the high-profile murder of a family of four, according to new reports.

The 40-year-old man, Wei Wei, was put to death by hanging.

Wei burglarized the home of 41-year-old clothing dealer Shinjiro Matsumoto in June 2003 and killed him, his wife and their two children in a conspiracy with two other Chinese men, Justice Minister Masako Mori said in the final ruling, according to Kyodo News.

The trio stole valuables from the family’s home and used weights to submerge the family in the Hakata port in the city of Fukuoka, Mori said.
