Great journey.

Respect for the solo travel, I plan a solo trip to Japan from the UK next March myself. I'll take the time to catch all the Japan vLogs on your channel & see how your journey turned out

You can drink while outside. No need to conceal it. However, don't take advantage of this and go wild and do crazy things in public. Japan is resisting the situation while drinking in public. Japanese and tourists are taking advantage of the situation.

How long were you at the airport? Did you buy a SIM card? JR pass ?

where's the beers?
