Meanwhile, the Health, Labor and Welfare Ministry said it has begun accepting calls from Nova teachers concerned about their salaries and job insurance at (03) 3204-8609 in Tokyo and (06) 6344-1135 in Osaka.

Administrators said the issue of salary payments will hinge on whether the administrators can find a sponsor to rebuild the company and when.

The company has failed to pay about 2,000 Japanese employees since July and about 4,000 non-Japanese instructors since September, according to a union representing foreign teachers employed by Nova.

According to market research firm Yano Research Institute Ltd., the market for English-language schools in Japan in 2006 shrank 5.2 percent from the previous year to ¥345.9 billion.

Even before the business suspension, Yano said the market would shrink amid the ongoing population decline.

METI's punishment on Nova's discount system for long-term lesson contracts, which helped expand the market in the past, will inevitably cause the language-school business to slow down, the institute said in a report in July.

Nova was founded in 1981 as Nova Planning Ltd. According to METI, Nova told prospective students they could book language lessons any time they want and at any school nationwide. However, many clients complained that they were not able to reserve lessons during busy periods.

The METI probe also revealed that several Nova schools did not give full refunds to people who canceled lessons.
