Despite bankruptcies,lay off and tighter comsumers spending,a few femaleled  businesses in Japan are developing well.

Shizue Hamada,52,set up a business in 1991 with eight other housewives-to care for the elderly and the physically disabled.

It wasn’t long before the Tasukeai Yui(mutual -aid group) earned a reputation for    its excellent  service. It now employs 200  staff  and  has  300 million  yuan(US $2.4million)in annual sales.

The woman said their business has been successful because they provide what  customrs really want.

These entrepreneurs are making use of a revalized  and  healthy demand  for everyday basic items.

Bread,for instance,is  in  high demand.Business  woman  Meiko Tanaka,26,started selling high-quality bread over the Internet in 2000.“Bread is cheap,”she said.“We migh  as well eat the bread baked using the the highest-quality ingredients.”

Five women—former office workers in their late 20s—have started the“OL Food Bureau of Investigation”to review restaurants on the  Internet.OL means young    office lady. It’s  a common nickname in Japan.

Business is increasing rapidly.Membership for their online magazine has reached 26,000. Their non-professional comments  seem to carry a lot of weight with consumers.This month the five women will be appearing on Japanese TV.

What all these female entrepreneurs have in common is a strong belief in their  likes and dislikes,and confidence is their own sensibilities.

They find gaps in the market and fill them with products and services that they like or want.

Japanese women headed nearly 6 percent of all  businesses in Japan at the end of  June—up from 4.5 per cent in 1999.

These female—led micro—businesses are playing an increasingly large role in the economy by plugging the gap between supply and demand.
