 Like for the English Oni, there are fifteen TSFT font files (normal, bold and italic variants in 7pt, 9pt, 10pt, 12pt and 14pt sizes). Each of them has a slightly larger pixel data array: there are no extended ASCII glyphs (96 of those), but the 154 kana more than make up for them, so the pixel data of the TSFTs ends up taking more than for English Oni, by 230,560 B overall.
-The main difference is size comes from the somewhat bloated use of auxiliary TSGAs for kana descriptors: in addition to the main TSGA used for regular ASCII (less that half full), there are 19 more TSGAs, totalling space for 4864 glyph descriptors (per TSFT), but filled very sparsely (only 154 kana glyphs are actually present). The excess space taken up by the 19 auxiliary TSGAs is about 100 kB (including instance headers, instance descriptors, and padding), so for the 15 fonts we get about 1.5 MB (about 30 times more than for the glyphs themselves, i.e., the pixel data in the TSFTs).
