Near my house there is a small park that has some ponies that kids can ride during certain hours. Recently they have changed the opening hours and to announce it making sure that everybody knows they have put these posters that combine shrewdly the “Change!” (changing the opening hours) and the “Yes, we can!” of Obama.
Really cool! At least they didn’t use Comic Sans.
In general, Japanese people and Japanese society don’t like to introduce changes very often. However there is always exceptions.
