According to a report by Shueisha, shop owner Yuichi Kawada revealed that his store originally had a notice reminding people to "Please avoid doing other things while eating." However, "During the lunch rush hour at the end of January this year, there was a customer who was eating noodles while watching pornographic videos. Even though he was wearing headphones, I happened to notice it. Such behavior, completely ignoring the surroundings, is too abnormal and terrible."
Kawada stated, "Although I didn't tell him to stop watching, I still said to him, 'Didn't you see the notice? Please leave,' and I asked him to leave." After the incident, the original reminder notice was escalated to "Using smartphones while eating is prohibited."
He mentioned, "That person looked like an ordinary male office worker in his 30s. He looked very normal, but he was eating and watching that kind of video in a public place. There were clear notices at the entrance and by the table, but he didn't look at or read them. I told him 'It says here please do not use your mobile phone,' and he replied 'Is that so?' In fact, most people who eat while looking at their phones react this way, and some even use the sign as a phone stand."
Kawada said that there is actually no rule saying you can't use your phone when entering the store, nor is it forbidden to take pictures before eating. But "sliding your phone while eating" slows down the pace of the meal, especially since thin noodles easily lose their texture if the time is dragged out. "As the shop owner, of course, I hope customers can enjoy the ramen in its best state."
Furthermore, ramen shops generally have low profit margins and must rely on turnover rates to maintain operations. If customers sit for a long time and don't leave, it may also affect the queuing crowd and overall revenue.
Such regulations are not isolated cases. The famous "Hakata Ramen Debuchan Takadanobaba Main Store" in the fiercely competitive ramen district of Takadanobaba in Tokyo set up a "Please avoid sliding your phone while eating" notice as early as 2023.
Shop owner Kota Kai pointed out, "Nowadays, even if young people come together, they slide their phones and eat individually. Even when it's fully seated, they don't care about the surroundings at all. There are too many customers like this, which is why the notice was set up." He said that when the notice was first put up, "the reaction was huge, and indeed some people stopped coming, but (people who slide their phones) haven't completely disappeared. I've sort of half-given up now."
Kai pointed out that "sliding your phone while eating" is not just a matter of personal etiquette, but it affects the operation of the whole industry. He stated bluntly that if this affects the turnover rate for a long time, it might cause pressure on the high-flow, low-margin business model of ramen shops. "To maintain this model, we have to rely on the understanding and support of customers."
As related issues continue to ferment, "whether smartphone use should be restricted during dining" has also sparked a debate between two sides. Opponents complain that "it's too excessive to be restricted even when eating a bowl of ramen"; supporters believe that "that kind of attitude is disrespectful to those who prepare the food" and "rather than meeting uncomfortable customers, it's better to make a clear announcement from the beginning." How to strike a balance between customer experience and store operations remains to be seen. (Editor: Tian Jui-hua) 1150419
