Cherry blossoms in full bloom in Kyoto

The cherry blossoms were in full bloom in Kyoto City, and since the temperature did not rise much after the blooming was declared, I was able to enjoy them for an unexpectedly long time.

Signs of spring in Kyoto.

demizunosidare-202203-1.jpg

Cherry blossoms were declared to have begun blooming on March 24. It seems that spring has begun in Kyoto.

So I took a stroll in Kyoto-gyoen national park to see how things are going. However, here was mainly composed of yamazakura (mountain cherry), satozakura (town cherry), and shidarezakura (weeping cherry), and no someiyoshino (Most popular cherry) is planted there, so I had nothing to do with the declaration of cherry blossom blooming.

The large weeping cherry tree on the Demizu creek is only about half in bloom. It will be in full bloom by the middle of next week. The satozakura and yamazakura cherry trees are still in bud, so it will be a while before they are in full bloom.

Peach blossoms are just at their best in the peach grove. Plum blossoms were late in blooming, so the late-blooming plums are at their best in the plum grove. Now we can enjoy full blooming of three spring flowers at the same time.

Walking in Kyoto Gyoen park in warm spring-like weather

gosho-ume-202203-1.jpg

For the first time this year, the temperature in Kyoto City exceeded 20 degrees Celsius, making the weather warmer.

I took a short walk in Kyoto Gyoen National Park. I used to come here often last year, but the very cold weather and COVID-19 have kept me away in this winter.

Plum blossoms were in full bloom around Demizu creek. In the plum grove, many of the plum trees were only half in bloom. If the warm weather continues, we will see much blooming this weekend.

The wax plum trees were also in full bloom.

Peaches grove were beginning to bloom with buds swelling considerably. The early-blooming weeping cherry trees are still hard in bud, so it will be a while before they bloom.

3.11 - 11th years of Great East Japan earthquake

sakura-sepia.jpg

Eleven years have passed since that terrible day.

Will time heal the painful and sad memories?
No, there must be something that we should not forget even if it is painful. The efforts to recover from the disaster caused by the massive tsunami and the nuclear power plant accident in Fukushima are still going on.

Now, many people in Ukraine are suffering and struggling. Their grief is our pain. We must not try to destroy the world peace order that was built on the reflection of the tragic events of World War II. May peace come to Ukraine!

Prayers for Ukraine from Nijojo Castle, Kyoto.

Kyoto_Nijojoh_for_Ukraine.jpg

Nijojo Castle in Kyoto, a World Heritage Site, was lit up in the colors of the Ukrainian flag!

Kyoto city and Kiev in Ukraine are sister cities, and this is an expression of solidarity with Ukraine and a wish for peace.

The current tragic war situation involving ordinary citizens is heartbreaking.

Furthermore, war attacks on nuclear power plants are criminal acts that endanger the existence of the entire human race, and cannot be tolerated for any reason. Calls for an immediate halt to the war of aggression against Ukraine.

Kind of Blue - World of fountain ink.

kind-of-blue.jpg

I never intended to get into anything other than audio, but...

In this age of COVID-19 disasters, I thought it might be good to immerse myself in another world for a little while. And now, I'm reexamining the world around me.

pelikan-royalblue.jpg

Now I'm becoming obsessed with fountain pen inks.

This is a "Pelikan Royal Blue" that I owned a few years ago.
It is a standard dye ink made in Germany, a very nice blue, and I was inspired by this color. (The top line in the photo above is this ink, a vivid blue with a purple tinge, but the exposure doesn't do justice to the color in this photo.)

Fountain pen inks have evolved to such an amazing degree that I am stunned by the state of modern inks.

salor-ink.jpg

Sailor's pigment inks, pure black "Kiwaguro", blue black "Seiboku" and "Souboku", have been my personal standard for the past seven years.

I was convinced that the current pigmented inks were good enough because they solved the critical problems of water resistance and ageing of fountain pen inks. The reason why I can use fountain pens normally for business purposes is because of the commercialization of pigment inks with ultra-fine particle nano technology.

So I never thought of going back to the origin of ink, dye ink.

But now, what kind of dye ink should I choose?

I tried to choose a few variations of blue ink based on the ink images posted on the Internet.

26-5207-02.jpg

There, I found Sailor's ink series "SHIKIORI" . It had as many as 20 color variations, and the exquisite naming was very enjoyable.

shikiori-1.JPG

In the end, I chose the blue inks "Souten" and "Yamadori", which have slightly different color tastes.

Here is a comparison of the two inks. Written with Sailor "Fude DE Mannen" (nib angle: 40 degrees).

kind-of-blue-2.jpg

Pelikan Royal Blue is a graceful purple-ish blue, Souten is the color of a clear early summer sky, and Yamadori is a deep green forest rather than blue.

Once again, I fell in love with the beauty of Pelikan Royal Blue. And in the future, I think I will use "Soten" more often as a new blue ink.

I was convinced that the ink madness is gradually increasing. Once again, I realized the richness of human sensitivity.

I'm going to try to immerse myself in the world of blue pigment inks for a while.

P.S. Hopefully, those in power should make every effort to bring about a peaceful world we can all feel a little happier. Never destroy it easily. No war!
