８月２５日（hachigatsu nijyugo nichi）： August 25

I went to the National Diet building. There is a tour of the building. The guide told us about the best position to take pictures of the building. From where you could take a picture of the building and the fountain. If you move a little bit, the building will appear with tall buildings.
I remember the idiom, mochi ha mochi ya (餅は餅屋), meaning leave the rice cake baker to rice cake making. That is the professional knows the best.

三月四日（sangatsu yokka）： March 4

It was cloudy in the morning but started raining in the afternoon and is still raining. They say it will be very warm tomorrow, but from the weekend it will be very cold again.

The cycle of warm days and cold days is expressed as san kan shi on(三寒四温) in Japanese, which is literally means three cold four warm. After repetition of three cold days and four warm days, spring will come.
This four words phrase is called yoji jukugo(四字熟語). Another idiom using the number three and four is cho san bo shi(朝三暮四), literally means morning three evening four. This is from the Chinese historical fact. The king was going to give the three treats in the morning and four treats in the afternoon to the monkey, but it got angry. And he said he would give four treats in the morning and three treats in the evening, and the monkey was very glad.
That means the result is the same after all, but they can't notice the difference.

四字熟語（yoji jukugo）: Four-character idiomatic phrase

Yoji jukugo(四字熟語) is the idiomatic phrase made of four kanji characters. There exists so many yoji jukugo. Today I would like to introduce some of them using the numbers.

First let's review how to count one to ten in Japanese. 1 is ichi (一), 2 is ni (二), 3 is san (三), 4 is shi or yon (四), 5 is go (五), 6 is roku (六), 7 is shichi or nana (七), 8 is hachi (八), 9 is ku or kyu (九), 10 is ju (十).

Isseki nicho (一石二鳥)literally means one stone two birds, that is to kill two birds with one stone.
Sankan shion (三寒四温) literally means three cold four warm, that is a cycle of three cold days and four warm days.
Gozo roppu (五臓六腑) literally means five internal organs six bowels, that is heart, liver, spleen, lung, kidney, small intestine, large intestine, gall bladder, urinary bladder, stomach and san jiao, therefore it means whole body or what is in mind.
Shichiten hakki (七転八起) literally means seven falls eight rises, that is undaunted perseverance to rise after a fall or repeated failures.
Jicchu hakku (十中八九) literally means ten among eight nine, that is in all probability of eight or nine cases out of ten.

Are there any yoji jyukugo you liked here?
