Depending on where you are located in Europe, you might actually be able to hear some of the broadcasts from France that are aimed at other parts of the world (depending also on the frequency band and its propagation characteristics) - for example, the one that I highlighted might be audible elsewhere in Europe, but the 0200 to 0400 UTC broadcast time may not be good for you unless you’re either a night owl or you get up very early in the morning.
If you have access to a shortwave radio receiver, give it a try. If you have some familiarity with shortwave radio, you may also be able to use a “Web SDR” to tune in radio broadcasts over the internet, with receivers located in different areas around the world - for example, I’m reasonably confident that the particular broadcast that I mentioned above can be tuned in on the K3FEF.com web SDR on 6105 kHz AM (during the times that I mentioned - click on the green button to start the audio):

If you hear interference you can try clicking the AM-nrw (narrow bandwidth filter) instead of the AM button to see if that improves your reception.
Right now (as I’m writing this) it’s about 2135 UTC - a quick look at the NHK Japanese Service schedule shows broadcasts from Japan aimed at SE Asia on 11630 kHz and aimed at the Asian continent on 11910 kHz - neither of those are particularly promising for an SDR located in the eastern US (and the K3FEF.com web SDR doesn’t like those frequencies for whatever reason) - but perhaps you could find a web SDR located in one of those areas of interest that can tune in to the NHK broadcasts.
