National lawmakers earned ¥24.12 million ($214,600) on average last year, up 6.3 percent from 2015, due partly to an increase in compensation, data from the Diet showed Monday.

The top earner was Upper House member Keizo Takemi of the ruling Liberal Democratic Party, who reported ¥471.57 million, up from ¥30.18 million the previous year, after selling his for-rent condominium in an upscale residential part of Tokyo.

The second-biggest earner was Lower House politician Tsuneo Akaeda of the LDP, who made ¥242.22 million, followed by his LDP colleague Akira Sato, with ¥137.30 million.
