You still need a sponsor for your cultural visa and that's why those who are in Japan under this visa, have been practicing ikebana or other cultural activities for certain amount of years.

Many of them are very serious and you have to have the right connection to get to know teachers and sensei.

Ikebana for example, is very expensive thing to do and it is mostly for girls. Also classes are not free and it could be very expensive.

Personally as a Japanese, I don't want some random people trying to exploit this visa option just so they could stay in Japan.
