The mighty and varied efforts made by SMAP fans to stop the breakup of the male idol group at the end of 2016 have been documented in a new volume published by a die-hard fan.

“SMAP ni Arigato” (Thank you for SMAP) features a campaign that collected more than 370,000 signatures, chartered streetcars decorated to demonstrate the adoration of fans and many other projects.

The “mook,” or half-magazine, half-book format publication, is priced at 926 yen ($8.30).

It was a pet project of a fan, now in her 50s, who had followed the group and attended their concerts for many years.

The fan, who goes by the name of Kuyan, came up with the idea after she was contacted in June 2016 by fellow fans asking her to meet up amid all the clamor surrounding the rumored SMAP’s disbandment.

“There were many people who were feeling upset,” Kuyan recalled. “I thought about whether there was anything we could do.”

Many SMAP fans discussed the issue on social networking services, but its fan base was wide-ranging and many didn't use smartphones. Kuyan had experience in book publishing and decided to act.

She spent more than four months since June 2017 visiting fans across Japan in her spare time to see what activities they were engaging in.

In Fukuoka Prefecture, SMAP fans created artistic sand messages on beaches. Streetcars decorated to show support for SMAP were seen in Hiroshima, Ehime, Nagasaki and Kagoshima prefectures. Members of a handicraft club called Sugeibu were showing their works modeled after their idols on SNS.

“If we can show them in a book, we can give a concrete shape to our feelings for SMAP and leave it behind for us fans and the world alike,” Kuyan said.

The mook covers 16 projects, regardless of scale. An eight-page advertisement placed in The Asahi Shimbun on the day before the disbandment to show fans' appreciation was also included.

But Kuyan had a difficult time finding a publisher. She was turned down by at least 20 companies, and Tokyo-based Makino Shuppan, which mainly focuses on health-related publications and has little expertise in entertainment, was the only publisher that took up the offer.

“I couldn’t say no to her enthusiasm,” said Junji Ogawa, who works at Makino Shuppan’s book editing department.

At the end of the mook, she included an interview with a lawyer familiar with issues surrounding contracts in the entertainment industry, which attracted attention due to the uproar over SMAP’s breakup and other ruckuses.

She hopes a system is established in which all showbiz personalities in Japan can work without any restrictions.

“I miss seeing them on TV. I want to share the feeling that we love them,” Kuyan said.
