In its ninth year, the event cost close to $2 million to organise this year and is the largest edition yet.
The festival's first edition in 2008 drew 27,000 visitors. Last year, the event had 90,600 attendees.
The mega festival has also gone regional. This year, it kicked off in Thailand in August, went on to Indonesia in September and is back on homeground this month.
Mr Shawn Chin, founder and managing director of local events and entertainment company Sozo, which organises the festival, says the event "brings a slice of every key component of Japanese culture to one place".
He adds: "In Japan, there are dedicated events for each genre - cosplay, music and anime - held at different times of the year. But we have condensed them all into three days."
He hopes to expand to Malaysia, the Philippines, Vietnam, Hong Kong and China.
The festival taps the small but dedicated Japanophile community in Singapore, which is up to date with the various sub-cultures and trends in Japan.
The Straits Times profiles three interest groups. The first is Singaporean girl group Tokimeki Jump, whose hobby was dressing up as Japanese maids at pop-up cafes and now are trying their hand at being singer- dancers. They are performing their debut show, a programme of anime songs and pop hits, at the event on Sunday evening.
The second is wotagei enthusiasts, that is, people who perform a super-synchronised dance with lightsticks while watching concerts and attending anime- related events. And lastly, The Straits Times features two new dedicated cosplay photo studios that have beautiful backdrops for the perfect anime-inspired photo series.
