Mishutecka -
Thank you!
s277400 - As far as I understand, with right brain education across the board (not just Shichida) 5 years old is not too late. In Japan, some of the children start as late as primary school and are still able to see results of right brain education. The focus of activities are different compared to say a toddler or preschooler, but the results can still be quite promising.
If you want an idea of what sort of activities they do in class, I have the Shichida home practice guide here:
