I've noticed when listening to some recordings of ん before a vowel, such as
`万{まん}円{えん}`, that the ん sound tends to be assimulated and almost vanish into
the vowel's sound (sounding almost like まーえん). But there's just a hint of a
naselization I think is being said, but I can't seem to replicate it at all,
and pronouncing it with a ŋ ('ng') sounds stronger than the recording.

I've searched some of the past questions on the site related to how ん is
pronounced prior to a vowel, but I haven't found a response that really gives
a precise answer, as most say 'nasalized vowel' without many instructions on
how to actually pronounced it.

Say あー, and while your breath lasts, hold your nose. If the sound changes, it
is nasalized. Practice till you can transition from the un-nasalized sound to
the nasalized sound smoothly without changing the position of your tongue.

Many natives say げーいん for げんいん (原因), and some say ふいんき for ふんいき (雰囲気). It
seems especially hard before い.
