Rice Field, Field
でん
た
None
The rice paddy radical and the rice paddy kanji are the same, making this one super easy to remember, at least meaning-wise.
To remember the reading た, we use the word "taco."
You're in the rice field... but when you lean down to examine the rice more closely, you see that it's not rice that's growing, it's a bunch of little tacos (た), blossoming out of the ground.
Currently there are no similar looking kanji which exist in the WaniKani learning system
