I think, the commercial point of view is strong in Japan. No, they cannot be commercialized because the purpose is different. But they are not aware that these organizations cannot act without money. They also have to make money as companies do. But the purpose is different.
Companies make money for themselves or for stockholders.
And NGO's make money to fund their next activity. Many Japanese believe that moneymaking is not a part of volunteer work, but actually it is necessary for volunteer activities. Unlike in Japan, in Europe and America it is easy to collect money through charities. The tax system also supports NGO's. As volunteer activities cannot be commercialized, the social and economical system supporting them is necessary for the development of the activity.
