Perspective on their fortune
Gold
Everyday luxury
A Tadashi Yanai & family's fortune is equivalent to 448 of gold, but this may be difficult to value, as we don't usually have a handful of gold bars in our piggy bank.
A standard gold ring typically weighs between 4 and 7 grams. Let's say this one weighs 5 grams. It's usually 18k gold.
Based on today's gold price (not taking into account the jeweler's fee, shipping, or anything else), that gold ring would be worth $556.3
Tadashi Yanai & family could buy 119,438,267 gold rings. That's a lot of fingers and a lot of gifts!!
And if the number of rings is difficult to visualize, all these rings would need 21 trucks to transport them, But we can be almost certain that Tadashi Yanai & family will have enough left over to pay for the gas for those trucks.
