In the land known for its advanced technology and hi-tech gadgets, Japan's music industry has chosen to keep things a little more traditional.
For loyal fans of the Japanese pop group Baby Raids, the chance to sing and dance with the group's five members apparently isn't enough.
They want to meet the girls one on one, to shake hands, to interact, maybe even to get a thumbs up.
The price of such an encounter? The tickets come free if you first buy their special edition CD single for between $10 and $16.
One enthusiastic fan bought 20.
"I want to shake hands, talk with them about stuff and be cheered up directly by them," said Suguru Hashiba.
CDs might be past their prime in many parts of the world, but in Japan they are still going strong. Physical media like CDs and DVDs make up 80% percent of music sales here compared to just 34% in the United States and 49% in Britain.
The Japanese now buy more CDs than consumers in any other country, and CD sales rose in 2012 while the number of digital downloads fell.
Industry experts say a major factor is the value Japan's consumers place on having a material item.
"One time, a foreign retailer told me that Japanese people don't mind the prices, but do care about what comes with the CDs. That made me realize that in Japan's packaged music culture, CDs always came with special goods like DVDs, booklets or photo albums," said Koto Taguchi, with the Recording Industry Association of Japan.
Artists have responded by issuing limited edition CDs, adding more elaborate packaging or intricate artwork. Another contributor to trend is age. Japan's customer base is getting older and clinging to the technology of their youth.
"Especially customers who are above late 30s who grew up in the packaged music era have the tendency to buy CDs," said Tatsuya Murakoshi, vice manager for Tower Records Shibuya.
This attachment translates to better profits for recording companies, which can charge more for each physical sale than a digital download.
The Baby Raids and other Japanese bands like it are trying to build on this trend, enticing supporters into buying 10 or 20 of each CD single, just to get the chance to spend more time with the girls.
"We can't be more thankful of them buying so many CDs just to talk to us," said Erika Denya, leader of Baby Raids.
A small price to pay for these devoted fans and one that's paying off for Japan's music industry.
