This is a four-character idiom that refers to someone who acts friendly toward everyone so as not to be disliked by anyone.
“Happō” means “in all directions,” and since it also includes the word “bijin” (beauty), you might think it has a positive meaning.
In reality, however, it’s often used with a slightly critical nuance to mean “a person who puts on a good face for anyone.” Trying to be liked by everyone can lead to saying inconsistent things and damaging relationships, so it’s something to watch out for.
unity; standing together as oneNEW!

Recommended for times when everyone wants to join forces and work hard toward the same goal.
For example, during a sports day relay, passing the baton while cheering each other on as a team is also a form of united teamwork.
The same goes for cleaning the classroom together as a class to make it neat.
It’s also important to have this spirit of unity when creating a play for a school festival or coordinating an ensemble for a recital.
This four-character idiom expresses a very uplifting and important mindset: by combining everyone’s strengths, you can succeed at things that one person alone could not accomplish.
A single smile is worth a thousand gold pieces.
Isshou Senkin is a beautiful four-character idiom meaning “a single smile or laugh is worth a thousand pieces of gold.” It teaches us that a heartfelt smile makes people happier than expensive things or money.
A smile that cheers up a friend, or a small laugh that soothes a family, has the power to brighten the atmosphere around us.
Valuing smiles in everyday life also helps us build good relationships with many people.
It’s easy to remember and conveys the importance of feelings.
It’s one of the four-character idioms I especially recommend for families with elementary school children.
