Letter rearrangement problem

There was a fad where people rearranged the letters of their own names to make other names, and this is a similar brain exercise where you rearrange letters to make sentences.
Even though it’s only four letters in this case, it can be surprisingly hard to find the correct answer.
It’s a light mental workout, but I recommend it for people who usually just watch TV all the time and don’t get much stimulation.
Cognitive Function Test for Senior Citizen Course, April 2026 – Official Exam QuestionsNEW!

It’s dangerous to drive a car when your cognitive function is impaired, right? So let’s try some problems similar to the cognitive function test given in senior driver courses.
There are two questions in total.
The first asks you to memorize all 16 pictures.
They’ll appear in groups of four, so remember them in order and then answer all of them at the end.
The second question asks you to write today’s date and the day of the week.
Hints are available, but you’ll get a higher score if you answer without hints.
Use this test to check your current level of cognitive function.
Showa Quiz

When we think of the Showa era, it has already become a sepia-toned generation, but recalling the past is actually great training for the brain.
This is a game that gathers quizzes about the Showa period, presenting several questions related to it.
Instead of just listening to the questions and giving answers, it might also be nice to remember related events or talk about them together.
“〇〇-shii” word search

It’s a brain-training activity called “◯◯-shii Search” that uses a whiteboard to look for words.
The idea is to list as many words as possible that end with “-shii,” such as “oishii” (delicious) and “ureshii” (happy).
Since some words don’t come to mind easily if you just think, you can write out the 50 Japanese syllables and fill them in to come up with many more.
Thinking this way helps train your brain!
What comes to mind when you think of ○ month? Onomatopoeia Quiz

A quiz like a word-association game where you ask, “What comes to mind when you think of [Month]?” and get an answer.
Then you expand the game by adding onomatopoeia—sound-symbolic words like sound effects and mimetic words.
For example, if you ask “What comes to mind for June?” the answer might be “the rainy season,” and the sound of the rainy season would be “pouring” or “pitter-patter.” You can also flip it around and show only the onomatopoeia and ask, “What sound is this?” which is fun as well.
Simple riddles about the seasons

A riddle quiz—simple questions related to the seasons.
After each question is presented, it stays on screen for one minute as thinking time.
If you can’t figure it out in a minute and want more time to think, pausing the video to ponder carefully is great brain training.
After all, thinking is training for your brain.
Even though they’re simple, you won’t get the answers unless you keep your mind flexible and supple!
LEGO

When you think of LEGO, you might picture children’s toys, but in fact there are many products aimed at adults as well.
From beautiful flowers and plants to adorable animals, and even models that rival plastic model kits like battleships and buildings… There’s a wide range of high-quality sets that, once completed, can double as interior decor.
They take patience to build, but they’re perfect for those who want to enjoy working steadily day by day over time.
Be sure to look for a LEGO set you’d love to create.
