Yoshihito Fujita, the man managing the Japan Spinning Top Museum from his own home in Nagoya, has standardized the names of different spinning styles, which vary depending on region, and has also established a ranking system.
To further spread these names and rankings, a national top spinning competition will be held next month at a park near the museum.
"This will be the culmination of all the work I've done so far, so I want to make it a success," said Fujita, 70, who is known as "koma no ochan" (spinning uncle).
