Trivia

It is important to choose a wedding gift envelope carefully, but what worries many people is how much money to put in it.

The average price varies depending on the relationship between you and the bride and groom, but it is said to be around 30,000 yen for friends.

I once went to as many as three of my friends' weddings in one month. At the time, I was living in Tokyo, so it was so hard to pay the already high rent, in addition, to the extra expenses of the gifts...I was on the verge of going bankrupt.

Here in Hokkaido, weddings generally require a membership fee. It's very helpful for me!

It's great to not have to think about things like "How much should I put in..." or "I need to prepare a gift envelope..."!

When you arrive at the wedding venue, only you have to do is pay your membership fee at the reception desk. Generally, the price is around 15,000 yen.

Other than that, wedding customs differ depending on the region, so it's a good idea to check with someone familiar with the area before you go.
