Does Japan B&B provide kettles?

Yes, European and American countries don't, because they hardly make tea. Coffee is also a special tool. Unlike us who use hot water to make instant noodles, they don't eat instant noodles. The living habits in Japan are similar to those in China. The Japanese also have the habit of drinking tea and hot water for instant noodles (instant noodles were invented by the Japanese). Even if not, you can ask the boss for some.

Actually, it's not just Japan. All Asian countries that eat with chopsticks are basically similar to Chinese mainland's living habits, and they can adapt to it soon when they get there.
