Interesting. Installed hanazono font HanaMinPlus.ttf in Firefox as J-default and even in this comment section the distinction between katakana 'n' and 'so' is quite clear whereas using MS Gothic it's somewhat ambiguous. Even more so when the two fonts are juxtaposed in LibreOffice.

You might want to look at some Kyokasho-tai typefaces; they should be pretty close to how we are taught to write.

awesome, thank you for actually being helpful rather than just downvoting and moving on!
