There is a myth that only children should play with toys. You might be right in America, but definitely not that correct in Japan. Japanese toys are connected with their anime and affect peoples of all ages. Many manufacturers such as Bandai financially support the anime production so that they will be able to manufacture toys. For examples, the very famous Gundam plastic models which are known as Gunpla in Japan not only have collectors among all ages but also have modeling competitions every year. Further more, many toys fairs such as Wonder Festival are held in Japan every year for those big companies to introduce their latest products. In some sense, Japanese do not treat them as toys but rather "garage-kit".
