This is a kindergarten
we designed in 2007.
0
6042
3698
00:22
We made this kindergarten
to be a circle.
1
10111
3925
00:26
It's a kind of endless circulation
on top of the roof.
2
14036
3142
00:29
If you are a parent,
3
17179
2520
00:31
you know that kids love
to keep making circles.
4
19699
3964
00:36
This is how the rooftop looks.
5
24793
2807
00:39
And why did we design this?
6
27600
2258
00:41
The principal of this kindergarten said,
7
29858
2817
00:44
"No, I don't want a handrail."
8
32675
2579
00:47
I said, "It's impossible."
9
35254
2229
00:49
But he insisted: "How about having a net
sticking out from the edge of the roof?
10
37483
6294
00:55
So that it can catch
the children falling off?"
11
43777
2209
00:57
(Laughter)
12
45986
1447
00:59
I said, "It's impossible."
13
47433
2076
01:01
And of course,
the government official said,
14
49970
2919
01:04
"Of course you have to have a handrail."
15
52889
3265
01:10
But we could keep
that idea around the trees.
16
58324
3519
01:13
There are three trees popping through.
17
61843
3277
01:17
And we were allowed to call
this rope as a handrail.
18
65120
5625
01:22
But of course, rope has nothing
to do with them.
19
70745
3272
01:26
They fall into the net.
20
74017
2486
01:29
And you get more,
21
77304
3051
01:32
and more,
22
80355
2937
01:35
more.
23
83292
1210
01:36
(Laughter)
24
84502
1151
01:37
Sometimes 40 children
are around a tree.
25
85653
3550
01:43
The boy on the branch,
26
91733
1248
01:44
he loves the tree
so he is eating the tree.
27
92981
2483
01:47
(Laughter)
28
95464
2500
01:50
And at the time of an event,
29
98984
1801
01:52
they sit on the edge.
30
100785
2266
01:56
It looks so nice from underneath.
31
104191
2372
01:58
Monkeys in the zoo.
32
106563
2089
02:00
(Laughter)
33
108652
3900
02:04
Feeding time.
34
112552
1766
02:06
(Laughter)
(Applause)
35
114318
4631
02:12
And we made the roof as low as possible,
36
120784
2529
02:15
because we wanted to see
children on top of the roof,
37
123313
4444
02:19
not only underneath the roof.
38
127757
2681
02:22
And if the roof is too high,
you see only the ceiling.
39
130438
3861
02:27
And the leg washing place --
there are many kinds of water taps.
40
135699
4516
02:32
You see with the flexible tubes,
41
140656
1778
02:34
you want to spray water
to your friends,
42
142434
2895
02:37
and the shower,
43
145329
1715
02:39
and the one in front is quite normal.
44
147044
2497
02:41
But if you look at this,
45
149541
1546
02:43
the boy is not washing his boots,
46
151087
1830
02:44
he's putting water into his boots.
47
152917
1674
02:46
(Laughter)
48
154591
1940
02:53
This kindergarten is completely
open, most of the year.
49
161423
5076
02:59
And there is no boundary
between inside and outside.
50
167699
3640
03:03
So it means basically
this architecture is a roof.
51
171339
4639
03:07
And also there is no boundary
between classrooms.
52
175978
3289
03:11
So there is no acoustic barrier at all.
53
179267
3594
03:15
When you put many children in a quiet box,
54
183590
5825
03:21
some of them get really nervous.
55
189415
3318
03:24
But in this kindergarten,
56
192733
2252
03:26
there is no reason they get nervous.
57
194985
3430
03:30
Because there is no boundary.
58
198415
2810
03:33
And the principal says
59
201225
2197
03:35
if the boy in the corner
doesn't want to stay in the room,
60
203422
4003
03:39
we let him go.
61
207425
1695
03:41
He will come back eventually,
because it's a circle, it comes back.
62
209120
3159
03:44
(Laughter)
63
212279
1962
03:48
But the point is,
in that kind of occasion,
64
216561
2995
03:51
usually children try to hide somewhere.
65
219556
2851
03:54
But here, just they leave and come back.
66
222407
4579
03:58
It's a natural process.
67
226986
1850
04:00
And secondly, we consider
noise very important.
68
228836
5023
04:07
You know that children
sleep better in noise.
69
235711
6431
04:14
They don't sleep in a quiet space.
70
242142
3844
04:17
And in this kindergarten,
71
245986
2250
04:20
these children show
amazing concentration in class.
72
248236
5247
04:27
And you know, our kind grew up
in the jungle with noise.
73
255193
6467
04:33
They need noise.
74
261660
2003
04:35
And you know, you can talk
to your friends in a noisy bar.
75
263663
4304
04:39
You are not supposed to be in silence.
76
267967
3961
04:43
And you know, these days
77
271928
2167
04:46
we are trying to make
everything under control.
78
274095
4474
04:52
You know, it's completely open.
79
280219
1802
04:54
And you should know that
80
282021
3012
04:57
we can go skiing in -20 degrees in winter.
81
285033
5785
05:02
In summer you go swimming.
82
290818
3104
05:05
The sand is 50 degrees.
83
293922
1844
05:08
And also, you should know
that you are waterproof.
84
296636
3393
05:12
You never melt in rain.
85
300029
3152
05:15
So, children are supposed to be outside.
86
303181
3869
05:19
So that is how we should treat them.
87
307050
3201
05:22
This is how they divide classrooms.
88
310251
2672
05:24
They are supposed to help teachers.
89
312923
2503
05:27
They don't.
90
315426
2305
05:29
(Laughter)
91
317731
1615
05:35
I didn't put him in.
92
323226
2156
05:39
A classroom.
93
327522
2184
05:42
And a washbasin.
94
330196
1909
05:44
They talk to each other around the well.
95
332655
3277
05:49
And there are always
some trees in the classroom.
96
337082
3737
05:55
A monkey trying to fish
another monkey from above.
97
343969
3408
05:59
(Laughter)
98
347377
1848
06:01
Monkeys.
99
349225
1604
06:02
(Laughter)
100
350829
1454
06:04
And each classroom has
at least one skylight.
101
352283
4415
06:09
And this is where Santa Claus
comes down at the time of Christmas.
102
357468
3997
06:19
This is the annex building,
103
367255
2427
06:21
right next to that
oval-shaped kindergarten.
104
369682
4469
06:26
The building is only
five meters tall with seven floors.
105
374151
5659
06:31
And of course,
the ceiling height is very low.
106
379810
2161
06:33
So you have to consider safety.
107
381971
4065
06:38
So, we put our children,
a daughter and a son.
108
386036
4381
06:43
They tried to go in.
109
391707
2534
06:47
He hit his head.
110
395731
2622
06:51
He's okay. His skull is quite strong.
111
399343
3969
06:55
He is resilient. It's my son.
112
403312
3088
06:58
(Laughter)
113
406400
1668
07:01
And he is trying to see
if it is safe to jump off.
114
409038
2860
07:05
And then we put other children.
115
413038
2667
07:12
The traffic jam is awful
in Tokyo, as you know.
116
420835
2541
07:15
(Laughter)
117
423376
1152
07:16
The driver in front,
she needs to learn how to drive.
118
424528
4851
07:21
Now these days,
119
429379
2531
07:23
kids need a small dosage of danger.
120
431910
4620
07:30
And in this kind of occasion,
121
438970
2405
07:33
they learn to help each other.
122
441375
3925
07:37
This is society. This is the kind of
opportunity we are losing these days.
123
445300
4435
07:48
Now, this drawing is showing
the movement of a boy
124
456065
6911
07:54
between 9:10 and 9:30.
125
462976
6324
08:01
And the circumference
of this building is 183 meters.
126
469300
6201
08:07
So it's not exactly small at all.
127
475501
3852
08:11
And this boy did 6,000 meters
in the morning.
128
479353
4606
08:15
But the surprise is yet to come.
129
483959
3592
08:19
The children in this kindergarten
do 4,000 meters on average.
130
487551
6697
08:27
And these children have
the highest athletic abilities
131
495455
6980
08:34
among many kindergartens.
132
502435
3155
08:43
The principal says,
133
511390
1626
08:45
"I don't train them.
We leave them on top of the roof.
134
513016
5727
08:51
Just like sheep."
135
519353
1619
08:52
(Laughter)
136
520972
1429
08:54
They keep running.
137
522401
1829
08:56
(Laughter)
138
524230
2029
08:58
My point is don't control them,
139
526779
5059
09:03
don't protect them too much,
140
531838
3222
09:07
and they need to tumble sometimes.
141
535060
3627
09:10
They need to get some injury.
142
538687
3786
09:14
And that makes them learn
143
542473
3419
09:17
how to live in this world.
144
545892
3136
09:23
I think architecture is capable
of changing this world,
145
551848
7209
09:31
and people's lives.
146
559057
1842
09:33
And this is one of the attempts
to change the lives of children.
147
561909
6082
09:40
Thank you very much.
148
568481
