Crazy fan or ardent supporter?

A wealthy Japanese woman moves into the same block in Nangang, south-east Taipei, as her idol, Taiwanese singer Jam Hsiao, and tries to surprise him with a supper of homemade shark's fin soup one night.

But he never opens his door and has her removed by security guards instead.

This episode was reported by Taiwan Apple Daily in July and the spurned superfan, Yuki Kageyama, has been back in the news after Hsiao had a bucket of excrement hurled into his van last month.

The faeces and urine missed him but hit his driver. Four men were charged in the case.

One suspect, Tseng Yi-cheng, said he had encouraged another man, Chang Che-chih, to take part in the attack after he met Kageyama and learnt of her unhappiness with Hsiao, reported China Times.

But Chang said he joined in the attack for another female fan who had been bullied at one of Hsiao's events.

Kageyama has protested her innocence and last week, the police said they would not question her yet because they had no conclusive evidence.

But for now, she is stuck with her media image as a scary fan.

Kageyama, who is said to be about 40, has been described as the only daughter of a Japanese technology businessman. China Times said she moved from Hong Kong to Taiwan early this year and set up an entertainment company to get VIP treatment at concerts.

Taiwan Apple Daily said she spent almost NT$100 million (S$4.2 million) on Hsiao, 26, in three years.

After she invested sums from NT$100,000 to NT$10 million in his concerts, she would ask to attend his press conferences and post-show parties to be photographed with him.

When he sang at Spring Wave Singapore in May, she spent NT$380,000 on 100 charity tickets to the music festival and also scored a front-row seat.

Things got uncomfortable in March, after a real estate agent convinced the fan to buy a NT$40-million flat downstairs from the singer and took her to see his motorcycle in the basement of the building.

Hsiao's agent Summer Lin sued the real estate agent after Kageyama posted a photo of herself with the bike online.

In July, the singer told the fan off on Facebook, a month after she moved in and hours after she pressed his doorbell around midnight and tried to give him the shark's fin soup.

He wrote: "How did you pass the guards to come to my house and take a photo with my bike? How did you pass the guards to come to my door in the middle of last night and keep pressing the doorbell? Please respect others and yourself."

In defence of her late-night visit, the fan said she had received a private message from the singer on Weibo but now knew it was a fake message.

She apologised to him on Weibo and said she would not approach him anymore.

But she also accused Lin of setting her up, a charge Lin denied. The agent said: "We thank her for her sponsorship and support, but too much love causes pressure."

Other extreme fans

Object of obsession: Singer Park Yu Chun, 27, of K-pop trio JYJ

Incident: Closed-circuit television images of Park hiding behind walls in a carpark emerged online in July last year. They were said to be proof that fanatic fans were spying on him, even in the carpark of his residence.

In March that year, Park and the other JYJ singers, Kim Jae Joong, 27, and Kim Jun Su, 26, had to apologise after an old audio file was leaked of them swearing at extreme fans.

But the stars said some stalker-fans had made their lives hell with methods such as installing global positioning system devices to track their cars.

Object of obsession: Heavenly King Andy Lau, 52

Incident: The father of Yang Lijuan, a fervent Andy Lau fan from Gansu, China, drowned himself in Hong Kong in 2007.

The Yang family had gone to the city for Lijuan, then 29, to attend a fan event and she was apparently unhappy after she got only a few minutes with Lau. Her father left a letter accusing the star of selfishness. He also blamed Lau for his family's poverty and demanded another meeting for his daughter.

The star said later: "You won't know my sorrow."
