JOIN USIn a posh supermarket in the centre of the capital, a lone sign stands where prior to the disaster there were mountains of toilet paper, tissues and paper towels.
"Due to the vast earthquake in the northeast, we are currently out of stock. We apologise for the inconvenience," the sign reads.
A 7-Eleven shop nearby is similarly stripped, while an outlet of rival chain FamilyMart is down to just four packs of tissue paper.
"Sorry, but it's one pack per customer. You can't have two," says the shop assistant with a sheepish smile.
Within hours of the 9.0-magnitude earthquake striking on March 11, sending a massive tsunami across Japan's northeastern seaboard, hordes of anxious consumers had rushed to the supermarkets.
They bought products they would need if they were to find themselves holed up at home for a lengthy period of time, including instant noodles, water, canned food, batteries -- and toilet paper.
As supermarket shelves were gradually emptied, people started turning elsewhere to meet their demands, reflected in appeals by companies for their employees to refrain from stealing toilet paper from the lavatories.
Acting almost as if by reflex, people prepared for any contingency, including a sharp increase in the price of daily necessities brought about by production halts, transport breakdowns -- and hoarding.
Japan has seen similar situations before. Many still remember 1973, when the great oil crisis spilled over into a great toilet paper crisis, with families accumulating huge stocks at home.
The current shortage in Tokyo is the result of damage to large paper mills in prefectures that were severely affected by the tsunami, including Miyagi, Fukushima and Ibaraki.
Industry data show that the day after the disaster, the residents of Tokyo also bought five times more instant noodles than normal and up to eight times more mineral water, causing prices to spike.
Production and delivery have been slow to pick up since then, because of damaged plants, impassable roads, fuel rationing and an inadequate supply of electricity.
However, early indications are that the situation is gradually improving, thanks to increased production at paper mills in western Japan, an area largely untouched by the disaster and its consequences.
