Ho-hum. Tokyo Disneyland and Tokyo Disney Sea recorded another record season. Between April and September, Japan's favorite theme parks were visited by 13.25 million people, a 23 percent increase over the same period last year, which is understandable given that "self-restraint" was the order of business in summer 2011 after the earthquake and tsunami. Still, that's an impressive increase under any circumstances since it translates as an operating income of ¥39 billion — double last year's — and a net profit of ¥25.5 billion — triple last year's.

But TDL isn't the only theme park that did well this summer. According to the Nihon Keizai Shimbun, attendance at Universal Studios Japan in Osaka was up 19.5 percent during the same period, Tokyo's Toshimaen amusement park saw an 18.7 percent rise, Yomiuri Land in western Tokyo 30 percent, Nagashima Spa Land in Mie Prefecture 3 percent, Fujikyu Highland in Shizuoka Prefecture 4 percent, and even the Dutch theme park Huis Ten Bosch in Kyushu, which almost went bankrupt before being bought by travel agent H.I.S., enjoyed an 11 percent year-on-year boost in attendance from Jan. to June.

Could all this healthy leisure spending be explained by a post-disaster recovery bump, as theorized by Sankei Shimbun? A recent segment of the TBS noon-time wide show "Hiruobi" looked into the matter and found that there's something else involved, namely a confluence of demographics that has resulted in wider-open wallets. The program sent a reporter to Universal Studios to cover the 100 millionth admission and found that a good portion of park attendance was made up of families of three generations, with the youngest layer comprised of very young children and the oldest of grandparents who are recently retired but still relatively young and, more importantly, have a lot of savings they're only too happy to spend on their grandkids. "My grandma buys me anything I want," said one little girl without shame.
