I am talking about numbers, days of week, months, counting people, counting items, etc. Things that make logical sense to be learned in one sequence from first to last. I have been at this for weeks and still cannot count in less than several minutes because it is so random.
It would be great to have some special section that teaches groups of items separately from the current model. It makes no sense to me to learn these things randomly, in different levels, and especially when they often have exceptional readings.
As a related feature, I would like to see a special test that generates random numbers or dates, lets you fill the readings and meanings and than check all at once. It can also ask for different things, like it shows date in english and you write the kanji and reading. Or it shows reading and you fill the kanji and meaning.
Learning to count days, things, and people is a pain in the butt no matter what, and I agree that it would be slightly easier to learn them all at once. I also strongly believe that theyβre better suited for ~level 5, but thatβs a whole different issue.
Everyone else here has struggled with this too. Something that will help is to use them yourself, either by speaking or writing/typing them.
This isnβt something that Wanikani will ever do. Itβs completely unrelated to the purpose of the site: learning kanji. The most they would do is group them into the same level.
There are other sites that offer services like what you requested though, like Sethclydesdale:
I use the Takoboto dictionary, and it has lists like that in is word list section.
The only way to really learn this properly is to use it all the time. I.e. just count stuff in your daily life. In a room with four people? γ²γ¨γγγ΅γγ²γγγγ«γγγγ«γ. Whatβs the date today? γ«γγγ«γγ γγγγγγγγγ€γγ«γγ γγγ«γ‘.
Tofugu has a lot of free resources like this on the blog:
As others do as well. Personally though, I have so much other stuff I need to prioritize learning that I donβt even bother with the βlistβ type stuff at this point and have just been picking it up accidentally along the way.
For example, yesterday I learned (I use the term loosely) from a friend that counting up and counting down are different in Japanese:
Itβs more like remembering the patterns, and βsomeβ exceptions. Some exceptions can be counted as vocabularies, and may be learned in sequence, or probably just selected ones.
Then, when reviewing the materials or perfecting the counting, remember the remaining exceptions.
Itβs more like grammar. Groups and rules are also found in appendixes of Dictionary of Japanese Grammar series.
