To target specific areas on his body, he just needs to ask his son to run his trains along routes at designated stations marked with helpful signage: “Right Shoulder,” “Left Shoulder,”“Spine,” and “Lower Back.”
Instructing his son to “send the express train from Spine Station to Right Shoulder,” means the trains must go extra-fast, allowing him to get a “more vigorous” massage.
Netizens were impressed with the cleverly devised shirt creation, Soranews24 reports.
“This is the greatest idea I’ve seen in years,” one user wrote.
“You can play with your kid and get a massage at the same time? Awesome!” another noted.
“You’re a genius,” said another one.
Some even offered their own suggestions to improve upon Kawamoto’s original idea, such as a shirt with tracks on the front or a jumpsuit so that the calves or hamstrings can be targeted as well.
Other parents also suggested a shirt with illustrated streets instead of tracks for those whose kids might fancy cars over trains.
