Feeling hopeless dating as a 32yo CF guy

After so many years of (online) dating, I've become extremely skeptic and frustrated at it, so much that I've been avoiding dating altogether. Everybody knows how difficult online dating is, but I feel like being CF adds another layer of complexity, where the dating pool shrinks even further. Especially as a guy in his thirties, since women my age have their biological clock and the instinct of becoming a mother knocking working overtime, I feel it's just a terrible time to find a CF girlfriend.

I lived for several years in Berlin, a city famous for having a terrible dating scene. I had dozens, if not hundreds of dates, and the few dates where there was a spark, it was either immediately killed by my date wishing children, or us juuust starting off a relationship and then realizing my girlfriend showing signs of really wanting to have children, for which I stepped aside in order to not waste her time.

I then specifically added a "Don't want children" filter in the apps, but this significantly reduced the amount of matches / likes that I had (which were already low, as an average looking guy on a dating app). Furthermore, CF women in Berlin tend to not vibe with me (party animals or pretty much digital nomads that travel at any occasion they have, for example). I'm a "regular" guy that doesn't club and travels once or twice a year, and instead focuses on career and hobbies, and would just look to have a regular life with my partner, just without the children. For a few years, I gave up.

I've been living in in Japan for the last few months, which reignited my hope on meeting a partner here. After all, Japan has one of the lowest fertility rates in the world, so I thought more women here would be against having children at all.

The dates have actually been super nice (I mean, the food here is amazing). I have gotten to meet many great women with who I seem to have much more in common that women in Berlin, in regards to career, hobbies and personality. However, surprisingly, I've already gotten a few rejections after a date or two due to my CF choice. Others, who told me that they feel indifferent about having kids, later message me that while they find me attractive and a nice guy, that they wish to find a life partner that is open to the idea of kids.

Of course, maybe they were just trying to be polite with their rejections, but I feel like at least some of them would be honest about their desire to have children as the dealbreaker, especially since we have gone on more than one date.

I am beyond frustrated at this point and don't know what to do. Using the "don't want children" filter in the apps yields me basically no matches, and even meeting women that are not sure about it, still want to date a man that wants children or doesn't know yet.

Any tips are greatly appreciated.
