Materials in the armour protection of modern tanks, especially Japanese ones, are one of the most classified topics of modern weapons and we do not currently have official documents of this kind. The protection of the tank was reconstructed on the basis of photo analysis, secondary (scientific popular magazines and monographs) sources, as well as available documentary assessments of the protection of other similar tanks, such as the recent Swedish presentation Stridsfordon_idag_och_imorgon, which first published estimates of the resistance of the Leopard 2A4 tank during the Swedish tender.
