Too big, too fast, and with too little quality — that's the consensus view of many industry analysts on former language-school market leader Nova Corp., whose collapse left over 420,000 students and 4,000 non-Japanese instructors without an "eikaiwa" home.

The Nova affair has already hurt many people: Hundreds of instructors have had to leave Japan and many of those who stayed are struggling to get by — the National Union of General Workers has even set up a "meals for English lessons" deal to help teachers and students. Meanwhile, customers who paid up-front fees to Nova are struggling to regain some of their substantial losses.

After Nova filed for bankruptcy with some ¥43.9 billion in debt, preparatory school operator G.communication took over some of its schools and rehired less than half of Nova's former employees.
