File.21 Learning Maekawa Architecture at Prefectural Youth Center
Miyuki Inoue (Magcal Editorial Department)

In the Momijigaoka area of Yokohama, the buildings designed by Kunio Maekawa, a post-war modernist flagship in Japan, are concentrated. The prefectural library and the prefectural music hall have already been guided by the tours, so the only one that remains is the Youth Center.
This time, I heard that there will be a “stage tour” tour by the hall staff and a lecture by Director Hashimoto of Maekawa Architects, in addition to the “Tomoe Tour” by the volunteer group bridge. saw.

The prefectural youth center was completed in 1962. Initially, it was a five-story complex with a theater hall, planetarium and science museum. After that, large-scale renovation work was carried out for the purpose of functional improvement and earthquake resistance. It was reborn in 2005 as it is today.
This major renovation received the 19th BELCA Award Best Reform Award as an excellent example of how to extend the life of public facilities. In 2018, DOCOMOMO JAPAN was additionally certified as a modern movement architecture in Japan, following the prefectural library and Ongakudo.

The library and music hall are masterpieces of the first period of Maekawa Architecture. On the other hand, the Youth Center is interesting because it was designed during the transition period from the second phase to the third phase, and has both characteristics.
One of the features is "precast concrete" used for window frames. Concrete plates are made in advance at the factory and assembled on site.

Another feature is the "driving tile". Since the surface of the exposed outer wall of the concrete will deteriorate, it is aimed to improve durability and design by covering it with large format tiles. It can be seen up close at the entrance of the hall, behind the main entrance.
By the way, each tile weighs about 10 kg (!). I nodded to the anecdote that it was unpopular with the construction workers.

During the 2005 major renovation, the major issue was to improve seismic performance while preserving and maintaining the appearance as much as possible. For this reason, we removed the planetarium, observatory, and floor slabs on the 4th floor to reduce the weight of the building and installed earthquake-resistant walls. It turned into a solid and sturdy three-story building.
Current, Looking up on the 3rd floor, I notice that there is a mysterious space at the ceiling. This seems to be a trace of removing the 4th floor slab.

Traces of the major renovation can also be seen on the stairs from the lobby on the first floor to the second floor. You can see that the "driving tile" used for the outer wall remains on the second-floor wall on the left side. Yes, this is an expanded area, which was once an outdoor space. Before the renovation, there was an outer staircase on the second floor, so the building was expanded from the perspective of convenience and a new staircase was newly established.

Speaking of the Youth Center, Koyosaka Hall!
This was also renovated in 2005, except for the walls, which were renovated. Of course, the acoustics, lighting, and other stage equipment have been redesigned, but it seems that the renewal of the curtain was also a major issue.
The curtain is by Japanese painting master Nei Sugiyama. Although it is a valuable item with only a few remaining in Japan, deterioration over time cannot be denied. Therefore, I carefully examined the original cloth and searched for the original color, and as with the previous time, asked the workshop in Kyoto, which is a thread binding and weaving, which is extremely rare for a cloth, to make it. It has been revived wonderfully.
By the way, some of the original curtains are displayed in the lobby, so please have a look when visiting the Youth Center.

The walls of the hall remain the same as before, but in fact, they are packed with ingenuity.
There is a structure called "Helmholtz Resonator", and there is a space for sound absorption on the back side of the tile, which controls the sound of the entire hall. The reverberation time is 1.8 seconds, which is slightly longer than that of the music hall. I thought it was just a design (sorry), so I was surprised when I was doing something physically amazing!

In addition to the guidance of the bridge members, this report was also referred to the lecture by Mr. Hashimoto, the director of Maekawa Architects.
Thank you very much!

Finally, another point.
This year, the plaza in front of the Youth Center has been improved to make it a pleasant space. The Kusunoki towering in the center is thought to be the same tree as the one depicted in the Ukiyo-e prints when the Kanagawa magistrate's office was set up on this land, and is now a symbol of Koyogaoka.
Maekawa cherishes the space that approaches the building, and himselfIt seems that there was a facility that designed a space called "dead". At the time of designing the Koyogaoka area, there seems to be no evidence of its name being used, but Director Hashimoto thinks that the newly-established space is suitable for being called <Esplanade>.
