"Lie" is a little harsh, don't you think?
It seems to me more of a misleading description of something that does exist, while "lie" suggests a deliberate falsehood with no basis in fact.
There are Japanese companies with kendo clubs, and some of those kendo clubs surely hold morning practice.
However, I would find it very strange if there was any company where everyone in the company was in the kendo club, and I'm almost certain that there is no company where participation in clubs is mandatory -- it defeats the purpose, honestly -- clubs are supposed to build up team morale, and being forced to participate would have the opposite effect.
In any case, even in companies that do have kendo clubs, that's because the company sponsors employee sports in general and there will also be clubs for other sports.
I've never worked for a Japanese company so I don't really know much beyond their existence, it seems much the same idea as the softball teams and bowling leagues that are common among American companies. It's an optional activity that takes place mostly outside of work hours that the company funds because it's a good way to keep the employees happy and build team spirit.
For a random example I googled up,

They
do have a kendo club, but they also have weightlifting, wrestling, track & field, and something called "goal ball", among others. So they might technically be a company that has Kendo practice every day, but it's not as dramatic as all that and would be more accurate to say they are a company with an employee sports program.
