Japanese modern art takes as many forms and expresses as many different ideas as modern art in general, worldwide. It ranges from advertisements, anime, video games, and architecture as already mentioned, to sculpture, painting, and drawing in all their myriad forms.
Many artists do continue to paint in the traditional manner, with black ink and color on paper or silk. Some of these depict traditional subject matter in the traditional styles, while others explore new and different motifs and styles, while using the traditional media. Still others eschew native media and styles, embracing Western oil paints or any number of other forms.
In sculpture, the same holds true; some artists stick to the traditional modes, some doing it with a modern flair, and some choose Western or brand new modes, styles, and media. Yo Akiyama is just one of many modern Japanese sculptors. He works primarily in clay pottery and ceramics, creating works that are very simple and straightforward, looking like they were created out of the earth itself. Another sculptor, using iron and other modern materials, built a large modern art sculpture in the Israeli port city of Haifa, called Hanabi (Fireworks).
Takashi Murakami is arguably one of the most well-known Japanese modern artists in the Western world. Murakami and the other artists in his studio create pieces in a style, inspired by anime, which he has dubbed "superflat". His pieces take a multitude of forms, from painting to sculpture, some truly massive in size. But most if not all show very clearly this anime influence, utilizing bright colors and simplified details.
