Privy Seal of Japan
Government offices and corporations usually have "inkan" specific to their bureau or company and follow the general rules outlined for "jitsuin" with the following exceptions. In size, they are comparatively large, measuring across. Their handles are often ornately carved with friezes of mythical beasts or hand-carved "hakubun" inscriptions that might be quotes from literature, names and dates, or original poetry. The Privy Seal of Japan is an example; weighing over 3.55 kg and measuring 9.09 cm it is used for official purposes by the Emperor.
