After sneaking inside through a smashed window, Lukka discovered millions of pounds worth of furnishings and two vintage Rolls-Royces. He also came face-to-face with the namesake of the properties: a huge taxidermied tiger worth $66,000 (£50,000) standing fiercely atop a green marble table. Sounds creepy, right?

Lukka, who made the trip from Bury, Manchester, also marvelled at untouched marble statues, chandeliers, gold-rimmed furniture, and a floor-to-ceiling view of the Pacific Ocean. The best view of the sea came after a 200 metre walk down an overgrown path to the biggest three-storey property of the extravagant estate. He said: ‘The view was just incredible, it stretched as far as the eyes could see.’ (Picture: Lukka Venuters/SWNS)

As for the Rolls-Royces, Lukka uncovered them on his way to the smallest property. Walking past a garage, the explorer decided to take a look inside. And he’s glad he did: ‘We opened it up and there we two cars under wrappers — when we lifted them up, they were both Rolls-Royces. It’s hard to believe that someone would just leave them there to rot almost.’ (Picture: Lukka Venuters/SWNS)

Looking at the ‘unimaginable’ wealth on display, he surmised that this type of luxury property could only have belonged to ‘someone really rich or a drug dealer.’ ‘Each room had thousands of pounds of artefacts lying around, just abandoned like they were worthless,’ the explorer said. ‘In its day, I could see this mansion in a James Bond film with the villain lying in a bath on the top floor smoking a cigar overlooking the spectacular sea view. It definitely gave off that 007 villain mafia vibe.’ (Picture: Lukka Venuters/SWNS)

Luke — whose online USP is to investigate abandoned buildings, which he shares on his YouTube channel, @‌lukkaVentures — said the whole experience was ‘unforgettable.’ He added: ‘The places I visit never cease to amaze me.’ (Picture: Lukka Venuters/SWNS)

The owner of the properties, which were built between the 1960s and 1980s, was controversial real estate tycoon Genshiro Kawamoto, who died in February 2024. In 2018, he was slapped with a four-year prison sentence and a 240,000 yen (£1.2 million) fine for money crimes committed between 2009 and 2011. (Picture: Lukka Venuters/SWNS)

Offences included concealing 3.543 billion yen (£19 million) in earnings and evading 1.06 billion yen (£5.6 million) in taxes. His incarceration is what led to the properties being abandoned. (Picture: Lukka Venuters/SWNS)

Unlike other abandoned properties in Japan, like this city of hotels left frozen in time for 30 years, Lukka said the Tiger Mansions were ‘trashed.’ This is unusual for Japan, which often has a very respectful culture — and a bizarre experience for Lukka, who said other derelict houses he’s visited in the country were in ‘top condition’ and virtually untouched. Lukka wondered: ‘The Japanese culture is very respectful — maybe they were damaged in an act of revenge, who knows?’ (Picture: Lukka Venuters/SWNS)
