BEIJING (AP) _ Premier Noburo Takeshita of Japan comes to Beijing Thursday on a six-day visit to point up recent improvements in Chinese-Japanese ties and offer new financial aid to reaffirm Japan's role in China's future.

It is the 64-year-old Japanese leader's first visit to China since taking office last November.

Premier Li Peng will welcome Takeshita in a ceremony outside the Great Hall of the People. The two will hold talks expected to focus on economic issues.

Takeshita is to meet separately with senior leader Deng Xiaoping; President Yang Shangkun, and the Communist Party general secretary, Zhao Ziyang, before leaving Beijing on Saturday for other areas of China.

His visit comes at a relatively trouble-free moment in the often-stormy relations between the two Asian neighbors. Officials from both sides agree the talks will be upbeat.

The official news agency Xinhua said the visit ''will be a major event of far-reaching significance in the political life of the Chinese and Japanese people.''

On Wednesday the national television evening news, in a rare profile of a visiting dignitary, gave a lengthy account of Takeshita's life.

Takeshita is to highlight the visit by announcing a new package of low- interest loans, estimated at $6 billion for Chinese development projects in the 1990-95 period.

He is also to sign an investment protection accord reached after seven years of sometimes acrimonious negotiations that will give Japanese investors the same tax and other benefits accorded to Chinese enterprises.
