Is there any high performance turbofan engine produce by Japan?

F100-IHI-220E is produced in Japan under a license from Pratt & Whitney.
Before you start drooling all over, remember you were the one who asked what is produced in Japan not developed.

Here is a list of all turbo fan engine that have been developed in Japan.
  • IHI F3
  • IHI XF5
  • IHI XF7
  • Honda Aircrafts HF118
You can also count IAE V2500 as well since Japan was part of the development team.

and it's a goldmine.

2. WS-15 development is encountering difficulties. It is currently in "stage C" which is the stage where preparations are made to mount the engine onto a ground-based testbed.

3. WS-20 probably won't be mounted on Y-20 this year.

4. In 2016, the WS-20's shaft broke during testing. This means QA is being revamped before WS-20 can proceed further. The latest picture that showed the WS-20 de-mounted from the Il-76 testbed aircraft is due to the need to replace and investigate the damaged WS-20.

This is bad news for china. IMO, WS-15 and WS-20 are the main aircraft engine programs for china.
Does this mean that WS-15 hasnt even begun ground tests ???

STOP this rant; I really have to condemn that comment !

Why do You deem this an offense esp., since he's new ?? IMO it is a perfectly valid question and google brings nearly nothing but contradicting news. As such and esp. since both engines are so important and we got news about their progress, thee latest reports about problems are indeed a reason to concern and esp. the report concerning that the WS-15 is strange.

So no need to rant ... just to argue and answer.

I was under the impression that WS-15 was already tested in a simulate high altitude facility (obviously ground based), meaning it should have technically already been on a ground based testbed? Or was that for the core only or something, or is the ground based testbed for Stage C a different sort of testbed?

And ouch, breaking a shaft during such an advanced stage of testing is nasty. Do we know if the WS-20 that broke would've been the same engine they've been testing for a while on the Il-76 testbed or if they've been testing something like LRIP equivalents of new WS-20s on the Il-76 testbed? (i.e.: whether the broken shaft is reflective of manufacturing defect at the prototype stage vs manufacturing defect due to early manufacturing stage)
