Koma Taisen is a highlight activity in “Vietnam Manufacturing Expo 2014”, which takes place in Hanoi from September 27th – 29th. This is a tournament that gather together small and medium sized manufacturing association (SME’s) from all Japan. These companies put all their soul in designing and making Koma (spintop) to participate in spintop fight battles.

The Koma (spin top) must have a diameter of 20mm. or less, smaller than a one yen coin. These small Koma (spintop) are designed and created with highly sophisticated unique “in-house” manufacturing techniques from participants from all over Japan. Koma (spintop), are great because at first glance you cannot notice the initial quality, however they have been manufactured with professional precision. The Koma enter the ring against their competitor and collide with each to fight to determine the winner. The overall winner of the competition will win all the Koma (spintop) from all the other participating competitors.

This is not about making business but to promote the prosperity of the manufacturing industry through competition of Koma showcasing skills and technology. Many small companies have not had the opportunity to product any of their own products because they are normally subcontracted to large technology companies.

Koma Taisen motivates these small companies to create Koma (spintop) that will participate of Koma (spintops) battles where people can see the
