A minor update today adds one common On reading (on-yomi) below the character on the Study pages. This was requested for Reviewing the Hanzi, and I figured it might be useful also here.

Please note there is only one On reading displayed per character. The intention is not to document fully each character but to provide an additional cue for the mnemonics, which is the main focus of the Study pages.

Also note that for very common Japanese characters there are often two or more common readings, therefore if the one you see is not the one you expected, it may just have a frequency that is slightly above another common reading.
