Sunday's Upper House election saw two Liberal Democratic Party candidates win in the five-seat Tokyo electoral district for the first time in 27 years, while a Japanese Communist Party candidate regained a seat for the first time in 12 years.

The Democratic Party of Japan, which was soundly trounced, failed to win a single seat in Tokyo, home of party leader Banri Kaieda. Twenty candidates vied for the five seats.

"I have to say we faced very harsh results. I apologize to my supporters," DPJ member Kan Suzuki told reporters in Shibuya Ward.
