Learn Maekawa architecture at File.21 Prefectural Youth Center
Miyuki Inoue (Magical Editor)

In the Momijigaoka area of Yokohama, buildings designed by Kunio Maekawa, the flagship of postwar modernist architecture in Japan. The prefectural library and the prefectural Ongakudo have already been toured, so the only thing left is the Youth Center.
This time, in addition to the "Tamomono Tour" by the volunteer group bridge, we heard that there was also a "stage backyard tour" by the hall staff and a lecture by Mr. Hashimoto, Director of Maekawa Architects, and went out immediately. saw.

The prefectural youth center was completed in 1962. Initially, it was a five-story complex with a theater hall, a planetarium, and a science museum. After that, large-scale renovation work was carried out to improve functions and improve earthquake resistance. In 2005 it was reborn in its current form.
This major renovation was awarded the 19th BELCA Award for Best Renovation as an excellent example of extending the life of public facilities. In 2018, it was selected by DOCOMOMO JAPAN as a modern movement building in Japan.

The library and the music hall are the masterpieces of the first phase of Maekawa architecture. The Youth Center, on the other hand, was designed during the transition from Phase 2 to Phase 3, so it seems interesting to have both features.
One of the features is "precast concrete" used for window frames. Concrete plates, etc. were made in the factory in advance and assembled on site.

Another feature is the “drive-in tile”. Since the surface of the exposed concrete wall deteriorates, it is intended to improve durability and design by covering it with large tiles. It can be seen up close around the entrance of the hall, behind the front entrance.
By the way, each tile weighs about 10 kg (!). I nodded greatly at the anecdote that it was unpopular with the construction workers.

In the major renovation in 2005, it was a major challenge to improve seismic performance while preserving and preserving the appearance as much as possible. For this reason, the planetarium, the observatory, the floor slab on the 4th floor, etc. have been removed to reduce the weight of the building and install earthquake-resistant walls. It turned into a sturdy three-story building.
CurrentLooking up, on the third floor, you notice that there is a mysterious space above the ceiling. This is a trace of removing the 4th floor slab.

Traces of the major renovation can be seen on the stairs leading from the lobby on the first floor to the second floor. You can see that the "drive-in tile" used for the outer wall remains on the left-hand second floor. Yes, this is an extension, a space that used to be outdoors. Before the renovation, the outer floor was used for the second floor, so the building was expanded for convenience and a new dedicated staircase was provided.

Speaking of the Youth Center, Momijizaka Hall!
This area was also largely renovated in 2005, except for the walls. Apparently, sound and lighting and other stage equipment were renewed, but the renewal of curtains was also a major issue.
The curtain is made by a Japanese painting master, Yasushi Sugiyama. It is a valuable item that has only a few items left in Japan, but it cannot be denied that it has deteriorated over time. Therefore, we carefully examined the original curtain and searched for the original color, and, as in the previous case, requested a workshop in Kyoto, which is engaged in the filling and weaving of a very rare curtain. The revival has been splendid.
By the way, some of the original stage curtains are displayed in the lobby, so you can see them when you visit the Youth Center.

The walls of the hall remain the same as before, but this is actually a great deal of ingenuity.
It has a structure called "Helmholtz's resonator", and there is a space for sound absorption behind the tiles, which controls the sound of the entire hall. The reverberation time is 1.8 seconds, which is slightly longer than the music hall. I thought it was just a design (I'm sorry), so I was surprised when I was doing something physically great!

In this report, in addition to the information provided by bridge members, I also referred to the lecture by Director Hashimoto of Maekawa Architects.
Thank you very much!

Finally, one more point.
This year, the plaza in front of the Youth Center has been improved and has become a pleasant space. The Kusunoki towering in the center is thought to be the same tree as the one depicted in the Ukiyo-e at the time the Kanagawa Magistrate's Office was set up on this land, and is now a symbol of Momijigaoka.
Mr. Maekawa values the space approaching the building and calls himself “Esplana.It seems that some facilities designed a space called "Ead". At the time of designing the Momijigaoka area, there seems to be no evidence of the use of the name, but Hashimoto considers that the newly constructed space is worthy of being called <esplanade>.

    The Prefectural Youth Center is a facility with the following four pillars to promote healthy youth development and contribute to the improvement of the culture of citizens of the prefecture. Working on
    1. Training human resources to promote youth experience learning
    2. Response to youth withdrawal, school refusal and delinquency
    3. Support for promoting youth science experience activities
    4.Supporting youth and prefectural performing arts activities
