Did you know that receiving a gift with both hands is a sign of respect in Japan
I heard about that as well. Also, it is seen as rude to present only one person a gift in front of a group of people
The business attire customs for Japan isn't really set in stone but it's usually just dress formally
And the attire for women is a formal too. They wear a suit but instead of trousers they normally wear skirts
Speaking of business. Their punctuality customs are be early if possible instead of just on time or late
Also when referring to someone in Japan. You use their last name instead of their first. And add an honorific such as -san or -kun based on the gender and their relationship with you
In Japan, they also say "Thanks for the meal" right before eating as a sign of respect
I don't know why, but they also take their shoes off before entering their own or someone else's house. and shrines too
Back to respect, people in Japan bow as a greeting, apology, or gratitude.
They also use Dogeza. which is kneeling on the ground and placing their head on the floor. They use this as a sign to a person of higher status, a deep apology, or to ask a favor of somoene
So what I got from this is basically that Japanese folk take respect and politeness very seriously.
