While everyone has their favorite brewery, label, and style, we can all agree on that irresistible refreshing sensation.
Here’s a bit of trivia about beer: the crimped edge on a bottle cap.
Do you know how many ridges it has? The answer is 21.

Japan’s first moving walkway debuted in 1967 (Showa 42). Do you know where it made its first appearance?
Moving walkways found in airports and large train stations look like escalators, but instead of taking you up or down a floor, they carry you straight ahead.
They’re faster than walking and let you glide smoothly to your destination, making them very convenient.
So, where did moving walkways first appear in Japan? Here’s a hint: it’s in Kansai, in a place known for people who are often in a hurry.
The answer is Osaka! The first one was installed at Hankyu Umeda Station.
At the time, the station was undergoing expansion, and the walkway was built to improve access from platform to platform.
By the way, you often see people walking on moving walkways, but it’s dangerous, so once you step on, stand still and ride it to your destination.
In 1970 (Showa 45), the local call charge for public telephones became 10 yen for 3 minutes. What had the pricing structure been like before that?
Public telephones used to be essential for making calls while out and about, but as time has gone on, we see them less and less.
Because opportunities to use them have decreased, many of us may no longer have a clear sense of the cost, but the rate is set at 10 yen for three minutes.
That “10 yen for three minutes” rate was introduced in 1970; before that, the pricing was different.
So what was the rate before 1970? The answer is “10 yen per call.” As long as you paid 10 yen, there was no time limit—your call would stay connected without worrying about the duration.
It’s worth noting the anecdote that many people would monopolize the phone for long periods because of this.
