Kyoto Gion Festival 2019 - 3


I went to the trial driving of the Houka-Hoko float in Kyoto Gion Festival today.

The Houka-Hoko float is located at Shimachi Shinjo. The float weighs about 10 tons and requires a lot of pullers.


There were fewer people than usual because of the rain, so I could grab the rope well.


It went north to Sinmachi-Rokkaku, changed the direction of the rope, south to Shinmachi-Sijo, and changed direction again and returned to home.


When it was over safely, participants was applauded naturally!

On the way, it was raining heavily, but I had a very enjoyable time.

Kyoto Gion Festival 2019 - 2

The production of the large "Hoko" float of the Gion Festival was completed, and there was the first driving of the "Hoko" float facing Shijo-dori in the afternoon.


In the evening, we went to see the "Yamahoko" float. There are still few visitors and I could tour leisurely.

In "Kukisui Hoko", it was playing the Gion music. It exudes an atmosphere of the Gion Festival.


In "Tuki Hoko", the staff broke up and was quiet.



In “Niwatori Hoko”, the lanterns are bright but there are no people at all.


"Iwatoyama" seems to be still in production. Tomorrow, it will mount the wheels and decorate the whole.


Other small "Yama" floats are still in production and will be completed by the day after tomorrow.

Kyoto Gion Festival 2019 - 1


From yesterday, Hoko float of Kyoto Gion festival started to be built.


There were three Hoko floats on Shijo Dori street, and the base part of Naginata Hoko float had been made.


There was also Mikoshi-arai ceremony of Gion Festival yesterday.
It was carried Mikoshi from Yasaka shrine to Shijo Ohashi bridge, and performed the purification ceremony by the water of Kamogawa river.

Nakagoza Mikoshi was waiting at Yasaka shrine before the ceremony.


Prior to Mikoshi procession, I could see carrying the big torch. There were too many tourists, so I could not take a picture of the purification ceremony at Shijo Ohashi bridge.

MOGAMI 3082 Speaker Cable


MOGAMI 3082 SuperFlexible Studio Speaker Cable

It is currently used as a main system speaker cable.

MOGAMI 3082 is a very flexible and easy-to-use speaker cable for professional audio, with an unusual coaxial structure as a speaker cable.

It has a very high resolution, well balanced frequency response and natural sound. Also it has excellent cost performance for professional use.

Having found this cable, I was able to stop using the expensive high-end cable. After all, I think it's better to gain the emphasis on tuning the audio system and the listening room.


MOGAMI 3082 uses a coaxial structure to maximize the conductor cross-section within a limited outer diameter. This standard speaker cable is designed to meet XLR audio connector cable clamp.
Mogami's cable designer said that this cable structure is the best speaker cable.

In fact, while the cable diameter is 6.5mm and very easy to use, both the center conductor and the shield conductor realize a cross section of 2.03mm2 (equivalent to 14AWG).

Because the MOGAMI 3082 has a coaxial structure, its wire processing takes a little more time.

It just peels off the jacket, bundles long ground wires, and insulates with heat-shrinkable tubes. Because the jacket is soft, it can be easily peeled off with a cutter knife.

New updated - "Vibroscope" ver 3.1


"Vibroscope" has been updated to ver 3.1.

"Vibroscope" is a powerful measurement tool for analyzing vibration by using iPhone's acceleration sensor in realtime. It allows you to monitor by visualizing the very low-frequency vibration such as inaudible by ear.

It can be intuitively detected an acceleration amount, that displays the two-axial coordinates in the horizontal direction and the time-axis waveform in the vertical direction.

vs_main_1_v310.png vs_main_2_v310.png

In the latest version, the logarithmic scale graph display function has been added. This is a display mode to detect minute vibration.


It is also equipped with the ability to analyze the frequency components of the very low frequency vibration by FFT analyzer.

It can be measured by determining the horizontal or vertical direction to suit the attitude of the iPhone, so as to be available in a placement of the floor and desk or Handheld.

Nakamichi CA-5 pre amplifier Repair - 1


Repairing the pre amplifier "Nakamichi CA-5" now!

I could easily obtain Nakamichi CA-5 Service Manual from the web.


When I looked at the electrical schematic in service manual, it seems to be a simple discrete circuit configuration.
Since it was a product of the mid-1980s, no surface mount components were used, and it was not a lead-free solder with a high melting point, so I seemed easy to replace components.


First of all, I checked the flat amplifier section of the main board, so I was relieved that it was working properly. This was probably due to the small number of parts, and the fact that heat stress was hardly added to the electronic parts by the proper component placement design.


Then, I examined the cause of the interruption of the left channel sound. The main variable resistor (NOBLE) was normal, but the balance variable resistor(ALPS) was found to be very unstable, causing contact failure even at the center position.

Once the balance variable resistor was bypassed and the input signal was sent directly to the main variable resistor, it became possible to reproduce without any problems. As I also cleaned the contacts of the signal connector, the sound freshness also increased.


The failured parts was ALPS Mini-dent resistor (RK27 series, MN type). It was easily obtained because of the audio parts currently being manufactured, but it did not the exist same resistance value parts.


When I replaced the balance variable resistor to new one, there was no break or noise in the playback sound, and it was played with a good sound.

Probably because the sound was made in the flat amplifier section, I felt that the low frequency range was very rich and dense, and the resolution was very high. It is a little different from the realistic monitor sound that can be heard on the Nakamichi's high-end tape deck.

Because I used a pure class A amplifier (Accuphase) as the power amplifier, it might have become a warm dense sound image that is the opposite of the cool realistic sound of my reference full digital amplifier (FOB SD05 - Feedback less power DAC).

The contact cleaning of the main variable resistor and switches need to be disassembled, so I will use it in my sub audio system for a while under this condition.

After a while, I will try to tune the sound while checking the details of this amplifier.

Sansho - Japanese pepper


The season for "Sansho" has arrived!

"Sansho" is a deciduous shrub from the genus Citrusaceae, which is native to Japan. Recently it has attracted attention around the world as a traditional Japanese spice. For example, it is used in Nouvel cuisine and sweets in France.

I purchased "Sansho" in Wakayama prefecture. It seems that the harvest period of the fruits of "Sansho" is about 10 days, and if it can not be obtained at this timing, it will become another production area.

I removed very small green fruits from the tufts and cleans them. It takes a lot of time for detailed work. It took about 3 hours and I got about 250g seeds.


I made "Sansho" flavored oil. It had just bottled green fruits with extra virgin olive oil. After washing in water, I think that it is safe to dry in hot water for about 30 seconds and then dry.

It was "1: 3" and "1: 4" weight ratio of "Sansho" and olive oil.

Usually, it is dipped in olive oil and it takes about a week to make a refreshing citrus flavored oil. Depending on the type of yam and olive oil, the extraction of aroma and pungent tastes is quite different.

In addition, I also made the salted ”Sansho" and the flavored vodka.


The ingredient "sanshool" contained in "Sansho" has been shown to activate the receptor (TRPV1) of capsaicin, a hot ingredient of chili pepper.

“Sansho” oil has a wonderful citrus flavor and spicy taste. Just sprinkle on the dish, it will provide a splendid fresh taste like you never experienced.
