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.


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


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


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.


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.


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.


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.


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.


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


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).


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!

Replaced the insulator of YAMAHA analog record player GT-2000L.


Yamaha Analog Record Player GT-2000L.

This is a great piece of audio equipment in the golden age of audio that I continue to use with great care.

The weight of GT-2000L is quite heavy, about 28kg, and the genuine insulator was screaming under the weight of years of use.

The genuine insulators were made of rubber and spring composite structure, and they were strong enough to withstand more than 12kg of weight per insulator, even if they were replaced with 18kg gunmetal turntable "YGT-1".

Now, it's in such a mess!


Two of the four insulators were damaged, especially one where the rubber adhesive had completely peeled off and the enclosed spring had popped out.


YAMAHA didn't have any spare parts in stock, which is not surprising since the product was almost 40 years old.

I've been looking for it on the Internet auctions, but I couldn't find any genuine insulators, so I had no choice but to use other insulators.

Last year, I found interesting parts among all the junk, such as audio cables and radios, in an item called "Audio Junk Set" on online auction.

I decided to bid on it at a very low price, and when I checked what I received...


This was a set of four genuine insulators for GT-2000. This was truly a grab bag!

They were in very good condition with very little apparent deterioration, and had probably been installed in GT-2000 for a short period of time.


After disinfecting and cleaning with alcohol, it caused a blooming phenomenon of the rubber. So I applied a little bit of KURE rubber protectant, and it returned to its original black tint.


As a test, I tried to find out how much difference there was in the degree of shock absorption between the old insulator and the new insulator.
I put my iPhone SE2 on the turntable and used the vibration analysis app "Vibroscope" to measure the difference.

- Measurement result of vibration absorption at OLD insulator

- Measurement result of vibration absorption at NEW insulator

This measurement was made when the GT-2000L was placed on the YAMAHA GT-rack "GTR-1W" and the rack shelf was hit hard by hand intermittently. The results show that the new insulator dampens external vibrations better than the old one. I tried to apply the same force as much as possible, but it is difficult to apply exactly the same kind of vibration, so this was just for reference.

Now I can enjoy original sound of the GT-2000L for the first time in over a decade. I'm sure it will be fine for another 10 years or so.
