The police in Osaka are now basically aware of what you are doing inside, it's just a matter of whether they will raid or not, as it is already illegal. Additionally, many bosses in Osaka used to buy entire buildings, which was very conspicuous; Tokyo is not that severe.

Tokyo is somewhat better

Definitely choose Tokyo, listen to Kabuki, haha.

I recommend Tokyo, as there are many Chinese IT companies in Tokyo, and it's hard to distinguish them from others. Osaka is too ostentatious.

Osaka now has too many people running over, it's a bit high-profile.

Osaka is not recommended for a visit right now, as inspections have been strict recently, with many police officers monitoring around the buildings.

Tokyo is expensive, Osaka is cheaper.

These two places, I could go there with my eyes closed.
