Tokyo- The Diet, Japan's parliament, adjourned for the summer after a 150-day ordinary session to Sunday, ending debates without clearing suspicion about Prime Minister Shinzo Abe's alleged influence over two school plans.

"To my regret, a lot of debate time was spent on scandals," Hakubun Shimomura, executive acting secretary-general of the ruling Liberal Democratic Party, said on television.

Meanwhile, Yoshihiko Noda, secretary-general of the main opposition Democratic Party, said the scandals indicate "the arrogance stemming from the longtime rule" of Abe's LDP.

In one scandal, the Cabinet Office allegedly cited Abe's "will" to urge the education ministry to move forward a plan for the Kake Educational Institution, run by a friend of Abe, to set up a university veterinary department in a special zone in western Japan.

But the Cabinet Office has denied making such a reference.

The other scandal centers on Moritomo Gakuen, also in western Japan, which received a huge discount on state-owned land it purchased as part of a now-scrapped plan to open an elementary school.

Moritomo Gakuen also solicited donations saying the school would bear the name of Abe and appointed the prime minister's wife, Akie, as honorary principal.

Abe has clearly denied any involvement in the land deal, but it remains a mystery why such a discount was awarded. The Finance Ministry, responsible for the transaction, has refused to make detailed explanations.

The opposition side said that Abe or at least those close to him seem to have worked to give favorable treatment to the two school operators. But Abe's side did not give enough explanations to dispel the suspicion.

The latest session was the first ordinary session since the LDP gained a single-handed majority in the House of Councillors, the upper chamber, for the first time in 27 years.

During the session, the government introduced 66 bills, of which 63 bills, or 95.5 pct, were passed into law. The share exceeded 90 pct for the first time in three years.

The enacted bills included special legislation to allow Emperor Akihito to abdicate, as well as anticonspiracy legislation that was rammed through the Diet amid opposition resistance and protests from many citizens.

The session was unusual in that the Diet skipped debates between the prime minister and the heads of opposition parties for the first time since the system, modeled on Britain's Question Time, began in 2000. (Jiji Press)
