Character column definitions use the character set assigned as the default for the user with CREATE USER and MODIFY USER. You can explicitly override the default character set definitions by using the CHARACTER SET clause. For example, if the DEFAULT CHARACTER SET defined by CREATE USER is Unicode for a user, whenever that user creates or alters a table, the declaration CHARACTER(n) in CREATE TABLE or ALTER TABLE is equivalent to CHARACTER(n) CHARACTER SET UNICODE.

You cannot specify a character server data set of KANJI1.
