Tokyo's 'oldest woman' missing for decades 
By Roland Buerk BBC News, Tokyo

Tokyo's reputed oldest woman has been missing for decades, Japanese officials have discovered as they made checks after the city's supposed oldest man was found to have died years ago.

Fusa Furuya, aged 113, had been registered as living with her daughter.

But the daughter says she has not seen her mother since the 1980s.

According to government data, there are more than 40,000 centenarians in Japan. But the discoveries in Tokyo have cast doubt on the accuracy of the figures.

Despite being reputed to be Tokyo's oldest woman, it appears no-one had bothered to check that Mrs Furuya was still alive - until now.

Local council officials have been visiting the very elderly after the body of Sogen Kato, thought to be Tokyo's oldest man, was found last week.

The police believe he had been dead for more than 30 years.

When officials went to Ms Furuya's home, they discovered that she had been missing for decades.

Her daughter told them she had not been in contact with her mother when she moved into the flat in 1986.

But she had registered her mother as living there, and kept paying her health insurance, just in case.

Efforts are now under way to trace Mrs Furuya's son to find out if she is living with him.

Tokyo's 'oldest man' had been dead for 30 years 

He was thought to be the oldest man in Tokyo - but when officials went to congratulate Sogen Kato on his 111th birthday, they uncovered mummified skeletal remains lying in his bed.

Mr Kato may have been dead for 30 years according to Japanese authorities.

They grew suspicious when they went to honour Mr Kato at his address in Adachi ward, but his granddaughter told them he "doesn't want to see anybody".

Welfare officials had tried to meet Mr Kato since early this year. But when they went to visit, family members repeatedly chased them away, according to Tomoko Iwamatsu, an Adachi ward official.

Authorities grew suspicious and sought an investigation by police, who forced their way into the house on Wednesday.

They discovered a mummified body, believed to be Kato, lying in his bed, wearing underwear and pyjamas, covered with a blanket.

Mr Kato's relatives told police that he had "confined himself in his room more than 30 years ago and became a living Buddha," according to a report by Jiji Press.

But the family had received 9.5 million yen ($109,000: 70,000) in widower's pension payments via Mr Kato's bank account since his wife died six years ago, and some of the money had recently been withdrawn.

The pension fund had long been unable to contact Mr Kato.

"His family must have known he has been dead all these years and acted as if nothing happened. It's so eerie," said Yutaka Muroi, a Tokyo metropolitan welfare official.
