Congratulations!! Looks like a wonderful wedding. My wife and I simply went the 入籍 route, with no ceremony or party. Looking at your photos, I don't know if I feel envy or relief.
We actually did the 入籍 back in October (we now have 3 anniversaries, it's a pain) but because of logistics with getting the family and relatives all together we had to wait until Summer. The ceremony wasn't that hard, as my mother in law put together everything for us. We just showed up, pretty much.. The hardest part was ferrying my parents and friends around while translating for everyone. My wife's family speaks no English and my Family speaks no Japanese. Even so, my mother and my mother in law can somehow communicate. It's the weirdest thing.
