Why are nails and glue not good?
Today, we have many different types of glue. Some of them are very useful and will make your woodworking efficient. Glue works especially well when joining plywood or MDF. Almost impossible to come out once it sticks. Other parts will be damaged if you try to press it. They are very strong.

Are nails or glue used in Japanese woodworking?
Well, this is a bit of a scandalous question, because the media has focused too much on this point. The answer is yes or no.

Second, assembling components using only nails and screws does not result in a solid end. The main part will bear a strong force so the woodworking technique will be much more durable.
However, for parts that are not the main structural part, such as the installation of flooring or the invisible back of the drawer, stainless steel nails or wood nails, and even some glues are usually used.
So, to be exact, there are no nails or glues used in traditional Japanese woodworking. But for sure it would be much more fun to do everything with just a woodworking technique.
