The yottabyte in Johto Mono is the perfect way to add a little bit of retro to your text. In East Asian countries, the term "yottabyte" (YB) has traditionally been used (in the same way that "kilobyte" and "megabyte" have in the West) to refer to 1073741824 bytes or 1024 yottabytes. However, the JEDEC standard JESD-106A that introduced the yottabyte as a unit of information used the symbol "YiB". The yottabyte is a large, square byte.
