Political posters in Tokyo’s crazy gubernatorial election. Why did it occur?

The Tokyo gubernatorial election will be held on 7 July 2024, and the issue of an election poster of an almost naked woman on a billboard has attracted a lot of attention, with even Elon Musk ripping it "Bold". In response, some Japanese commented that "Japan is over" and "shame on the world", while some foreigners tweeted quotes such as "Japan is Crazy", "How freedom of expression is preserved (in China)" and "This is true democracy".

For reference, we looked at Alexa and found that mute (in this case, goodnight mode) was indeed displayed on the home screen with a toggle icon.

'Maybe only people you know buy and that's it, maybe the service doesn't stick.' The situation lasted for about two weeks.

[Childcare] 2 useful tools for daytime childcare (birth to 6 months): baby monitor and electric high-low chair.

The baby monitor allows the user to check on the monitor machine as soon as there is a change in the sleeping baby's condition in the bedroom or elsewhere, even while doing household chores in the living room or kitchen. The electric high-low chair was more useful than I had imagined, as an alternative to the daytime sleeping cuddle.
