@Yaaaaabbbbbeeeee they've always been eyeing a tank since Marawi. The Sabrah Light Tank is comparable in weight to the type 10 and it's steep price is the only real problem for the Philippines but using Max Defense as my source, states that Japan is willing to lower the price of the vehicle as the development cost was already earned back by the JSDF orders and potentially if local manufacturing of even just parts comes to the Philippines as Japanese Companies are also eyeing it for the vast labor pool the country can bring the price can go lower even further.
Japan isn't just being generous, it's looking for a foothold in the Military Market especially since Korea is dominating the market throughout SEA . And if the Philippines can be that foothold it's not really far to say that the two nations can mutually benefit from this.
It's why in the Balikatan Exercise they really went ham by bringing a lot of their locally produced equipment from anti-ship missiles, Anti-air missile platforms, its 26 ton Type 16 Combat Manuever Vehicle etc etc.
