The Philippines is in the process of a substantial upgrade of its Coast Guard and it is getting a lot of help form Japan. They already have a contract for the delivery of ten 44 meter patrol craft, that fill a role similar to our own Webber class WPCs. The first of these can be seen on sea trials in the video above.
Now we have reports that the Japanese will be building two new much larger, 295 foot (90 meter) cutters for the Philippines. These may be an entirely new design, but it is more likely it will be closely related to a existing Japan Coast Guard design.
Which class seems likely? They will almost certainly be Kunigami class like the ships in the videos below.

I haven’t been able to find a speed for the class, but apparently they are 1,700 tons full load, 96.6 m x 11.5 m (length 317 feet, beam 38 feet). They have a helo deck, but no hangar. They appear to have three boats, two smaller ones on davits, and a larger boat launched by crane. The gun is probably a 20 mm Sea Vulcan Gatling gun.
None of the Philippine CG vessels have a weapon larger than an old 20 mm and almost all have .50 cal. (12.7 mm) M2 crew served machine guns and/or lighter weapons. If they wanted to mount something larger, the Mk38 mod2 (or 3) 25 mm is likely, since it recently entered service with the Philippine Navy.
Perhaps more importantly, the Japan Coast Guard ships also have a water cannon that might come in handy.
