I mean all industries dump pollutants into rivers, so I don’t think that’s a stretch. And as for mnemonics, you can and should use the ones you’re most comfortable with ^-^ WK’s mnemonics are just one of the many possibilities.
I did the same. I mean Kawasaki fits perfectly and can be used for future mnemonics. For the life of me I don;t get the connection with cow… what accent is that???
It’s not meant to be exactly the same sound. It’s just meant to be a memory trigger. Just like how ‘two’ is used often as mnemonic for a つ reading even though they don’t sound the same.
I’m a Skip Beat fan so even if 川 wasn’t incredibly easy for me to remember I can’t help but always think of this. Even if it’s not really a mnemonic it just sticks out in my mind and all I really need to remember is かわ <D
In Norwegian, to “kave” is the motions you do when you’re panic-ing in water. Like if you accidentally fell into a river you would “kave” for a bit before beginning to swim / float. In past tense “kave” turns to “kava”, which is pronounced like the Japanese “Kawa” (At least in my dialect).
For some reason, the “kawa” pronunciations in my head all turn into “Kawa kawa kawa kawa Kawa Chameleon~” which is. Not exactly how the song goes, but at least I can easily think of chameleons chilling by the river.
