Japan is set to acquire four Northrop Grumman E-2D Advanced Hawkeyes airborne early warning aircraft that would nullify the threat of Chinese stealth fighters and afford it a potent missile defense capability. The new aircraft is equipped with a powerful hybrid mechanical/electronically scanned UHF-band radar that will be able to tie into the U.S. Navy’s state-of-the-art Naval Integrated Fire Control—Counter Air (NIFC-CA) battle network.
Japan’s purchase of the E-2D is significant because the capabilities of those two key features. The E-2D’s Lockheed Martin AN/APY-9 UHF-band radar is the central feature of the Advanced Hawkeye. Both friend and foe alike have touted UHF radars as an effective countermeasure to stealth technology. One early public example of that is a paper prepared by Arend Westra that appeared in the National Defense University’s Joint Forces Quarterly academic journal in the 4th quarter issue of 2009. “It is the physics of longer wavelength and resonance that enables VHF and UHF radar to detect stealth aircraft,” Westra wrote in his article titled Radar vs. Stealth.

Why wouldn't Japan remain a close ally?

The Japanese AAM-4B air to air missile is one of the best and most capable air to air missiles in the world. The only missile currently better than it is the Israeli Python 5. The AAM-5 will be the most capable IR missile anywhere in the world.

All well and good purchasing a couple of radars, but I really don't think Japan could beat China by detecting their stealth fighters.

Despite whatever weaponry barr nuclear China would always defeat Japan just on sheer numbers alone.
