New Leaf ' s English translation began in March 2012 by members of Nintendo of America's "Treehouse" localization group, who collaborated with the company's headquarters in Japan on creating in-game events.  The North American and European versions contain an extra feature not included in the Japanese release - the ability to download example home layouts in the Happy Home Showcase from Nintendo over the internet using the SpotPass feature in addition to StreetPass , which requires players to physically pass by one another. According to localization manager Reiko Ninomiya, this was added due to the difficulty players in those regions experience with meeting others in public who own the game, explaining that "in Japan Streetpass happens really, really frequently. People take trains. It’s a different community culture. Here, you’ve got people living in remote parts where they don’t have an opportunity to pass by people who have the game."
