Help needed! Brit in Japan

Oh dear, we have managed to start this trip off spectacularly bad! My baggage never made it to Japan, and debit card is missing. Which means i can't get cash out which I have quickly realised is essential in Japan. I thankfully have cards on google wallet but i have noticed alot of places you cannot do wireless payment. For example public transport. And I tried tapping the credit card on my phone to get theough barriers on the subway but it did not work. All the money exchanges I have stumbled across so far will only exchange cash for cash... So i cant even get money that way. Any suggestions about how to solve this issue? If any Brit is local to Osaka currently and is willing to meet up where I bank transfer £ and you get cash out at an ATM that would be great. Also where is best to get some basic clothes/underwear? Thank you

Update: Thanks we got money from western union! And KLM is apparently sending luggage tonight! Fingers crossed. Thank you all for your help 🙏
