In Europe we have the "Wedding Day" because everything is done in about One Day: Ceremony, Signature, Lunch, Party and Pictures.
In Japan I call it "Wedding Period" because the process is a little different. The picture you see above is during the so called "2nd Party". But let's go in order...
First, the couple goes (alone, just the two of them) to the City Hall to bring their documents and sign that they want to be married. That's it. They are now married. No friends, no family, no witnesses. Just the two of them and the City Hall officials. 2 Minutes and it's done.
Then, after that, the couple will take some pictures togheter at the studio or on location, like the following one, in traditional White wedding Kimono.

At the first party, guests are expected to pay either 30,000 or 50,000 yen ($300 or $500). $100 is too little money, $200 is an even number so cannot be used because doubling it would become $400 that contains '4' that is pronounced similar as "death" (4 is pronounced "Shin" and death is pronounced "Shinu"). Therefore the ones left are $300 or $500. Of course you could go for the next odd one which is $700...but would be maybe too pricey.
After the ceremony, the member of the first party, will have lunch or dinner with the newlyweds. After that they'll go home or participate to the second party.
At the second party are all other friends not in the first category. At this party (that I've attended) I paid around $80 to participate. People is not expected to give gifts. The $80 is to pay for the refreshments and the Party Hall. Nice place, but the whole thing lasted about 2 hours, so is kind of a short party...we entered around 6.30 and at 9.00 PM everyone went home.
