Somewhat similar to modern offices, partitions within the house are created by fusuma, sliding doors made from wood and paper, which are portable and easily removed. Fusuma seal each partition from top to bottom so it can create a mini room within the house. On the edge of a house are rōka, wooden floored passages, that are similar to hallways. Rōka and ima are partitioned by shōji, sliding and portable doors that are also made from paper and wood.
