Drinking coffee at a coffee shop is a common activity, as people often go to coffee shops or cafes to get out of the house and change their mood.

Coffee shops often use better beans and brew using better methods than those you can get at home, so you can enjoy coffee that you wouldn't normally get. They also have a stylish or retro atmosphere.

They're also used as social venues. If you're drinking alcohol, it's an izakaya, but if you're not, it's a coffee shop. They're perfect for meetings, dates, and conversations with friends.

Coffee is a popular drink. It's incredibly popular all over the world. Many people use it as a morning alarm clock, to refresh themselves between work or study, or as part of cafe culture.
In Japan, coffee is widely available at convenience stores, cafe chains, and specialty coffee shops.
Coffee has a rich aroma and a complex flavor that stimulates the brain, including bitterness, acidity, and rich sweetness.
This is why people drink coffee when they wake up in the morning or before work.
