I chose 5 fun factors I wanted to share with my blog readers.

1: Hiding Thumbs in Front of Hearse

There is a saying in Japan that you will not make it to your parent's deathbed if you don't hide your thumb when you see a hearse.
Thumb is Oya Yubi in Japanese. Oya means parents and yubi means finger.
Hiding the thumb means to protect your parents.

2: Triple Car Light Flash

We flash our car lights three times as a thank you when someone lets you in when making a lane change while driving. And it looks like this is an only-Japan thing.

3: Mayonnaise Pizza

It is normal in Japan to have mayonnaise, corn, potatoes and even boiled eggs on a pizza. But I noticed that many people are surprised when they see the Japanese style pizza.

4: Salty Watermelons and Tomatoes.

We sprinkle salt on watermelons and tomatoes to make the sweetness stronger. I always thought that was a lie but I finally tried it a couple years ago and I understood what others were trying to say. It does taste sweeter!

5: Toilet Slippers
This is probably famous. You will find a pair of slippers for toilet use only. If you ever encounter this situation, it is polite to place the hole of the slippers towards the door so the next person can put them on easily.
