Do companies have special celebrations for achieving certain anniversaries? For example, in America a restaurant might celebrate its 20th anniversary. Is this a 'hatachi' anniversary in Japan? Is it more important than other anniversaries?
I used to work for a company that valued a good relationship with their employees in Japan. The company celebrated their 40th anniversary by giving everyone a special clock with their company’s name on it.
But I think they celebrate in different ways depending on their budget.
