The tensor renormalization group is a very attractive approach for numerically calculating lattice field theory. It does not suffer from the sign problem, and it is a method that enables calculation with an extremely large volume lattices and direct calculation of free energy. I report on recent developments in this field and clarify the problems to be solved in the future.
