A Mitsubishi Materials press release (Japanese) announces that the company has cast the world's largest gold bar. The 250kg bar is pictured above alongside a more typical 1 kilo bar. If beaten out into gold leaf, the gold would cover an area of 70,000 tatami mats (over 2.6 Tokyo Domes). The company's previous record, a 200kg bar, was beaten by a Taiwanese company's 220kg effort last year. Mitsubushi Materials has immediately applied to the Guinness Book of Records for recognition.

I would have been more impressed if they actually did use the 220+kg to cover an area that large.

A gold bar is just a block of material

Kyodo have the story in English:

Mitsubishi Materials makes world's largest gold bar
Mitsubishi Materials Corp said Thursday it has made the world's largest gold bar weighing 250 kilograms and filed for a listing in Guinness World Records. The gold bar, valued at 400 million yen (about $3.7 million), measures 45.5 centimeters by 22.5 cm at the base and is 17 cm high, it said. The gold bar, made at its Naoshima refinery in Kagawa Prefecture, will be put on show at a tourist facility in Izu, Shizuoka Prefecture, from July 11.

Fools gold, some other place said it kinda hollow and wasn't even 24 Carrat Gold

I don't think Mitsubishi is that corrupt

Where's that going to be on display again?

Also, times that it will be unattended, security systems in place, number of guards, easily accessible exits would also be helpful
