大化の改新
In the Taika Reform, the Funeral Simplification Edict was proclaimed, and the building of large "kofun" (tumuli) was banned. The edict also regulated size and shape of "kofun" by classes. As a result, later "kofun", though much smaller, were distinguished by elaborate frescoes. Paintings and decorations in those "kofun" indicate the spread of Taoism and Buddhism in this period; the Takamatsuzuka Kofun and Kitora Kofun are notable for their wall paintings.
