First off, I would seriously hold off on the trip if you can. If you're in the states then you're fully aware that the CDC is projecting the pandemic to peak around April-May and has classified Japan as a Level 2 threat, so unless it's absolutely necessary I would stay home for now. I've got lots of friends working as flight attendants who fly into Japan every week and they're fine, but it's their job--no sense taking an unnecessary risk.
Second, Osaka is a stunted, backwards shithole full of stunted, backwards morons. Unless you're fluent in Japanese (and even then you're still probably fucked) you will have next to zero chance of getting accepted at Tobita right now. They already discriminate against browner Asians during normal days of the week, and now that Chinese are Public Enemy #1 there's probably an across-the-board ban on all non-Japanese Asians until this outbreak is over.
Third, I grew up around Filipinos and how you've managed to stay a virgin--given how inherently, culturally and wonderfully horny Filipino girls are--is beyond me, but trust me on this: You do NOT want to try losing your virginity somewhere like Tobita. You've got 20 minutes on the clock and you have no fucking idea what you're doing. It might take you 15 minutes just to find the right hole. You're not allowed to kiss. You're often not even allowed to touch very much. It is straight-up cold service and once you've busted the show's over and get the fuck out.
Given that you're either going to take forever to figure out which crack to stick your dick in or, more likely, are going to blow like Jim from American Pie, and also given that you want a GFE, do some research and hire an independent like the ones here on TAG. Pay for 90 minutes or more. Then you've got plenty of time, GFE is a definite and the providers will be far, far more understanding and accommodating and you can rest assure that you aren't the first 40yo virgin they've met.
