1
00:00:00,359 --> 00:00:02,008
Hi. I am an architect.

2
00:00:02,008 --> 00:00:04,456
I am the only architect in the world

3
00:00:04,456 --> 00:00:07,772
making buildings out of paper like this cardboard tube,

4
00:00:07,772 --> 00:00:10,338
and this exhibition is the first one I did

5
00:00:10,338 --> 00:00:11,846
using paper tubes.

6
00:00:11,846 --> 00:00:16,271
1986, much, much longer before people started talking

7
00:00:16,271 --> 00:00:20,474
about ecological issues and environmental issues,

8
00:00:20,474 --> 00:00:23,764
I just started testing the paper tube

9
00:00:23,764 --> 00:00:26,499
in order to use this as a building structure.

10
00:00:26,499 --> 00:00:31,652
It's very complicated to test the new material for the building,

11
00:00:31,652 --> 00:00:34,150
but this is much stronger than I expected,

12
00:00:34,150 --> 00:00:36,362
and also it's very easy to waterproof,

13
00:00:36,362 --> 00:00:38,257
and also, because it's industrial material,

14
00:00:38,257 --> 00:00:40,960
it's also possible to fireproof.

15
00:00:40,960 --> 00:00:44,793
Then I built the temporary structure, 1990.

16
00:00:44,793 --> 00:00:47,800
This is the first temporary building made out of paper.

17
00:00:47,800 --> 00:00:51,870
There are 330 tubes, diameter 55 [centimeters],

18
00:00:51,870 --> 00:00:53,512
there are only 12 tubes with a diameter

19
00:00:53,512 --> 00:00:56,282
of 120 centimeters, or four feet, wide.

20
00:00:56,282 --> 00:00:58,902
As you see it in the photo, inside is the toilet.

21
00:00:58,902 --> 00:01:01,553
In case you're finished with toilet paper,

22
00:01:01,553 --> 00:01:03,873
you can tear off the inside of the wall. (Laughter)

23
00:01:03,873 --> 00:01:06,265
So it's very useful.

24
00:01:06,265 --> 00:01:10,304
Year 2000, there was a big expo in Germany.

25
00:01:10,304 --> 00:01:12,923
I was asked to design the building,

26
00:01:12,923 --> 00:01:15,717
because the theme of the expo was environmental issues.

27
00:01:15,717 --> 00:01:20,205
So I was chosen to build the pavilion out of paper tubes,

28
00:01:20,205 --> 00:01:21,932
recyclable paper.

29
00:01:21,932 --> 00:01:24,902
My goal of the design is not when it's completed.

30
00:01:24,902 --> 00:01:26,986
My goal was when the building was demolished,

31
00:01:26,986 --> 00:01:30,962
because each country makes a lot of pavilions

32
00:01:30,962 --> 00:01:34,062
but after half a year, we create a lot of industrial waste,

33
00:01:34,062 --> 00:01:38,743
so my building has to be reused or recycled.

34
00:01:38,743 --> 00:01:40,846
After, the building was recycled.

35
00:01:40,846 --> 00:01:43,492
So that was the goal of my design.

36
00:01:43,492 --> 00:01:46,580
Then I was very lucky to win the competition

37
00:01:46,580 --> 00:01:49,238
to build the second Pompidou Center in France

38
00:01:49,238 --> 00:01:50,713
in the city of Metz.

39
00:01:50,713 --> 00:01:52,209
Because I was so poor,

40
00:01:52,209 --> 00:01:54,376
I wanted to rent an office in Paris,

41
00:01:54,376 --> 00:01:55,893
but I couldn't afford it,

42
00:01:55,893 --> 00:01:57,934
so I decided to bring my students to Paris

43
00:01:57,934 --> 00:02:01,450
to build our office on top of the Pompidou Center in Paris

44
00:02:01,450 --> 00:02:02,685
by ourselves.

45
00:02:02,685 --> 00:02:06,014
So we brought the paper tubes and the wooden joints

46
00:02:06,014 --> 00:02:10,099
to complete the 35-meter-long office.

47
00:02:10,099 --> 00:02:13,133
We stayed there for six years without paying any rent.

48
00:02:13,133 --> 00:02:17,004
(Laughter) (Applause)

49
00:02:17,004 --> 00:02:19,391
Thank you. I had one big problem.

50
00:02:19,391 --> 00:02:21,745
Because we were part of the exhibition,

51
00:02:21,745 --> 00:02:25,049
even if my friend wanted to see me, they had to buy a ticket to see me.

52
00:02:25,049 --> 00:02:27,252
That was the problem.

53
00:02:27,252 --> 00:02:30,020
Then I completed the Pompidou Center in Metz.

54
00:02:30,020 --> 00:02:31,974
It's a very popular museum now,

55
00:02:31,974 --> 00:02:35,140
and I created a big monument for the government.

56
00:02:35,140 --> 00:02:37,039
But then I was very disappointed

57
00:02:37,039 --> 00:02:39,635
at my profession as an architect,

58
00:02:39,635 --> 00:02:43,663
because we are not helping, we are not working for society,

59
00:02:43,663 --> 00:02:46,907
but we are working for privileged people,

60
00:02:46,907 --> 00:02:50,099
rich people, government, developers.

61
00:02:50,099 --> 00:02:52,619
They have money and power.

62
00:02:52,619 --> 00:02:54,416
Those are invisible.

63
00:02:54,416 --> 00:02:58,244
So they hire us to visualize their power and money

64
00:02:58,244 --> 00:03:00,462
by making monumental architecture.

65
00:03:00,477 --> 00:03:02,642
That is our profession, even historically it's the same,

66
00:03:02,642 --> 00:03:04,994
even now we are doing the same.

67
00:03:04,994 --> 00:03:08,318
So I was very disappointed that we are not working for society,

68
00:03:08,318 --> 00:03:12,305
even though there are so many people

69
00:03:12,320 --> 00:03:15,212
who lost their houses by natural disasters.

70
00:03:15,212 --> 00:03:18,255
But I must say they are no longer natural disasters.

71
00:03:18,255 --> 00:03:21,240
For example, earthquakes never kill people,

72
00:03:21,240 --> 00:03:23,413
but collapse of the buildings kill people.

73
00:03:23,413 --> 00:03:25,453
That's the responsibility of architects.

74
00:03:25,453 --> 00:03:27,190
Then people need some temporary housing,

75
00:03:27,190 --> 00:03:28,852
but there are no architects working there

76
00:03:28,852 --> 00:03:32,512
because we are too busy working for privileged people.

77
00:03:32,512 --> 00:03:36,391
So I thought, even as architects,

78
00:03:36,391 --> 00:03:41,147
we can be involved in the reconstruction of temporary housing.

79
00:03:41,147 --> 00:03:42,939
We can make it better.

80
00:03:42,939 --> 00:03:46,972
So that is why I started working in disaster areas.

81
00:03:46,972 --> 00:03:50,698
1994, there was a big disaster in Rwanda, Africa.

82
00:03:50,698 --> 00:03:53,430
Two tribes, Hutu and Tutsi, fought each other.

83
00:03:53,430 --> 00:03:55,928
Over two million people became refugees.

84
00:03:55,928 --> 00:03:59,679
But I was so surprised to see the shelter, refugee camp

85
00:03:59,679 --> 00:04:01,913
organized by the U.N.

86
00:04:01,913 --> 00:04:05,207
They're so poor, and they are freezing

87
00:04:05,207 --> 00:04:07,330
with blankets during the rainy season,

88
00:04:07,330 --> 00:04:10,085
In the shelters built by the U.N.,

89
00:04:10,085 --> 00:04:12,391
they were just providing a plastic sheet,

90
00:04:12,391 --> 00:04:16,540
and the refugees had to cut the trees, and just like this.

91
00:04:16,540 --> 00:04:18,306
But over two million people cut trees.

92
00:04:18,306 --> 00:04:21,097
It just became big, heavy deforestation

93
00:04:21,097 --> 00:04:22,830
and an environmental problem.

94
00:04:22,830 --> 00:04:26,060
That is why they started providing aluminum pipes, aluminum barracks.

95
00:04:26,060 --> 00:04:28,347
Very expensive, they throw them out for money,

96
00:04:28,347 --> 00:04:30,273
then cutting trees again.

97
00:04:30,273 --> 00:04:34,294
So I proposed my idea to improve the situation

98
00:04:34,294 --> 00:04:36,454
using these recycled paper tubes

99
00:04:36,454 --> 00:04:39,387
because this is so cheap and also so strong,

100
00:04:39,387 --> 00:04:42,134
but my budget is only 50 U.S. dollars per unit.

101
00:04:42,134 --> 00:04:45,095
We built 50 units to do that as a monitoring test

102
00:04:45,095 --> 00:04:50,801
for the durability and moisture and termites, so on.

103
00:04:50,801 --> 00:04:55,381
And then, year afterward, 1995, in Kobe, Japan,

104
00:04:55,381 --> 00:04:57,174
we had a big earthquake.

105
00:04:57,174 --> 00:04:59,686
Nearly 7,000 people were killed,

106
00:04:59,686 --> 00:05:02,677
and the city like this Nagata district,

107
00:05:02,677 --> 00:05:05,995
all the city was burned in a fire after the earthquake.

108
00:05:05,995 --> 00:05:09,936
And also I found out there's many Vietnamese refugees

109
00:05:09,936 --> 00:05:12,531
suffering and gathering at a Catholic church --

110
00:05:12,531 --> 00:05:14,450
all the building was totally destroyed.

111
00:05:14,450 --> 00:05:17,951
So I went there and also I proposed to the priests,

112
00:05:17,951 --> 00:05:20,569
"Why don't we rebuild the church out of paper tubes?"

113
00:05:20,569 --> 00:05:23,709
And he said, "Oh God, are you crazy?

114
00:05:23,709 --> 00:05:25,818
After a fire, what are you proposing?"

115
00:05:25,818 --> 00:05:29,446
So he never trusted me, but I didn't give up.

116
00:05:29,446 --> 00:05:31,328
I started commuting to Kobe,

117
00:05:31,328 --> 00:05:33,957
and I met the society of Vietnamese people.

118
00:05:33,957 --> 00:05:36,624
They were living like this with very poor plastic sheets

119
00:05:36,624 --> 00:05:37,905
in the park.

120
00:05:37,905 --> 00:05:41,147
So I proposed to rebuild. I raised -- did fundraising.

121
00:05:41,147 --> 00:05:43,703
I made a paper tube shelter for them,

122
00:05:43,703 --> 00:05:46,661
and in order to make it easy to be built by students

123
00:05:46,661 --> 00:05:48,244
and also easy to demolish,

124
00:05:48,244 --> 00:05:51,453
I used beer crates as a foundation.

125
00:05:51,453 --> 00:05:54,043
I asked the Kirin beer company to propose,

126
00:05:54,043 --> 00:05:56,763
because at that time, the Asahi beer company

127
00:05:56,763 --> 00:05:58,775
made their plastic beer crates red,

128
00:05:58,775 --> 00:06:01,189
which doesn't go with the color of the paper tubes.

129
00:06:01,189 --> 00:06:03,507
The color coordination is very important.

130
00:06:03,507 --> 00:06:06,700
And also I still remember, we were expecting

131
00:06:06,700 --> 00:06:09,055
to have a beer inside the plastic beer crate,

132
00:06:09,055 --> 00:06:10,949
but it came empty. (Laughter)

133
00:06:10,949 --> 00:06:14,341
So I remember it was so disappointing.

134
00:06:14,341 --> 00:06:16,579
So during the summer with my students,

135
00:06:16,579 --> 00:06:18,765
we built over 50 units of the shelters.

136
00:06:18,765 --> 00:06:21,536
Finally the priest, finally he trusted me to rebuild.

137
00:06:21,536 --> 00:06:23,827
He said, "As long as you collect money by yourself,

138
00:06:23,827 --> 00:06:26,081
bring your students to build, you can do it."

139
00:06:26,081 --> 00:06:28,564
So we spent five weeks rebuilding the church.

140
00:06:28,564 --> 00:06:32,062
It was meant to stay there for three years,

141
00:06:32,062 --> 00:06:35,360
but actually it stayed there 10 years because people loved it.

142
00:06:35,360 --> 00:06:39,169
Then, in Taiwan, they had a big earthquake,

143
00:06:39,169 --> 00:06:43,119
and we proposed to donate this church,

144
00:06:43,119 --> 00:06:44,720
so we dismantled them,

145
00:06:44,720 --> 00:06:46,965
we sent them over to be built by volunteer people.

146
00:06:46,965 --> 00:06:50,589
It stayed there in Taiwan as a permanent church even now.

147
00:06:50,589 --> 00:06:53,080
So this building became a permanent building.

148
00:06:53,080 --> 00:06:57,729
Then I wonder, what is a permanent and what is a temporary building?

149
00:06:57,729 --> 00:06:59,662
Even a building made in paper

150
00:06:59,662 --> 00:07:03,192
can be permanent as long as people love it.

151
00:07:03,192 --> 00:07:05,488
Even a concrete building can be very temporary

152
00:07:05,488 --> 00:07:07,505
if that is made to make money.

153
00:07:07,505 --> 00:07:10,215
In 1999, in Turkey, the big earthquake,

154
00:07:10,215 --> 00:07:14,365
I went there to use the local material to build a shelter.

155
00:07:14,365 --> 00:07:18,219
2001, in West India, I built also a shelter.

156
00:07:18,219 --> 00:07:22,300
In 2004, in Sri Lanka, after the Sumatra earthquake

157
00:07:22,300 --> 00:07:25,981
and tsunami, I rebuilt Islamic fishermen's villages.

158
00:07:25,981 --> 00:07:31,432
And in 2008, in Chengdu, Sichuan area in China,

159
00:07:31,432 --> 00:07:34,358
nearly 70,000 people were killed,

160
00:07:34,358 --> 00:07:37,443
and also especially many of the schools were destroyed

161
00:07:37,443 --> 00:07:40,893
because of the corruption between the authority and the contractor.

162
00:07:40,893 --> 00:07:43,861
I was asked to rebuild the temporary church.

163
00:07:43,861 --> 00:07:47,647
I brought my Japanese students to work with the Chinese students.

164
00:07:47,647 --> 00:07:50,508
In one month, we completed nine classrooms,

165
00:07:50,508 --> 00:07:52,160
over 500 square meters.

166
00:07:52,160 --> 00:07:56,632
It's still used, even after the current earthquake in China.

167
00:07:56,632 --> 00:08:02,096
In 2009, in Italy, L'Aquila, also they had a big earthquake.

168
00:08:02,096 --> 00:08:04,448
And this is a very interesting photo:

169
00:08:04,448 --> 00:08:07,165
former Prime Minister Berlusconi

170
00:08:07,165 --> 00:08:11,583
and Japanese former former former former Prime Minister Mr. Aso --

171
00:08:11,583 --> 00:08:15,464
you know, because we have to change the prime minister ever year.

172
00:08:15,464 --> 00:08:20,426
And they are very kind, affording my model.

173
00:08:20,426 --> 00:08:24,825
I proposed a big rebuilding, a temporary music hall,

174
00:08:24,825 --> 00:08:27,269
because L'Aquila is very famous for music

175
00:08:27,269 --> 00:08:28,694
and all the concert halls were destroyed,

176
00:08:28,694 --> 00:08:30,826
so musicians were moving out.

177
00:08:30,826 --> 00:08:32,253
So I proposed to the mayor,

178
00:08:32,253 --> 00:08:34,488
I'd like to rebuild the temporary auditorium.

179
00:08:34,488 --> 00:08:37,434
He said, "As long as you bring your money, you can do it."

180
00:08:37,434 --> 00:08:38,617
And I was very lucky.

181
00:08:38,617 --> 00:08:40,918
Mr. Berlusconi brought G8 summit,

182
00:08:40,918 --> 00:08:43,024
and our former prime minister came,

183
00:08:43,024 --> 00:08:46,229
so they helped us to collect money,

184
00:08:46,229 --> 00:08:49,072
and I got half a million euros from the Japanese government

185
00:08:49,072 --> 00:08:51,959
to rebuild this temporary auditorium.

186
00:08:51,959 --> 00:08:56,679
Year 2010 in Haiti, there was a big earthquake,

187
00:08:56,679 --> 00:08:58,270
but it's impossible to fly over,

188
00:08:58,270 --> 00:09:01,287
so I went to Santo Domingo, next-door country,

189
00:09:01,287 --> 00:09:04,202
to drive six hours to get to Haiti

190
00:09:04,202 --> 00:09:07,493
with the local students in Santo Domingo

191
00:09:07,493 --> 00:09:10,946
to build 50 units of shelter out of local paper tubes.

192
00:09:10,946 --> 00:09:14,559
This is what happened in Japan two years ago, in northern Japan.

193
00:09:14,559 --> 00:09:16,434
After the earthquake and tsunami,

194
00:09:16,434 --> 00:09:20,221
people had to be evacuated in a big room like a gymnasium.

195
00:09:20,221 --> 00:09:22,122
But look at this. There's no privacy.

196
00:09:22,122 --> 00:09:24,989
People suffer mentally and physically.

197
00:09:24,989 --> 00:09:28,380
So we went there to build partitions

198
00:09:28,380 --> 00:09:31,643
with all the student volunteers with paper tubes,

199
00:09:31,643 --> 00:09:35,874
just a very simple shelter out of the tube frame and the curtain.

200
00:09:35,874 --> 00:09:38,390
However, some of the facility authority

201
00:09:38,390 --> 00:09:40,437
doesn't want us to do it, because, they said,

202
00:09:40,437 --> 00:09:43,634
simply, it's become more difficult to control them.

203
00:09:43,634 --> 00:09:46,116
But it's really necessary to do it.

204
00:09:46,116 --> 00:09:48,621
They don't have enough flat area to build

205
00:09:48,621 --> 00:09:51,906
standard government single-story housing like this one.

206
00:09:51,906 --> 00:09:54,156
Look at this. Even civil government is doing

207
00:09:54,156 --> 00:09:58,285
such poor construction of the temporary housing,

208
00:09:58,285 --> 00:10:04,816
so dense and so messy because there is no storage, nothing, water is leaking,

209
00:10:04,816 --> 00:10:08,085
so I thought, we have to make multi-story building

210
00:10:08,085 --> 00:10:11,110
because there's no land and also it's not very comfortable.

211
00:10:11,110 --> 00:10:16,040
So I proposed to the mayor while I was making partitions.

212
00:10:16,040 --> 00:10:19,671
Finally I met a very nice mayor in Onagawa village

213
00:10:19,671 --> 00:10:20,991
in Miyagi.

214
00:10:20,991 --> 00:10:25,377
He asked me to build three-story housing on baseball [fields].

215
00:10:25,377 --> 00:10:28,103
I used the shipping container

216
00:10:28,103 --> 00:10:30,556
and also the students helped us to make

217
00:10:30,556 --> 00:10:33,354
all the building furniture

218
00:10:33,354 --> 00:10:35,046
to make them comfortable,

219
00:10:35,046 --> 00:10:37,321
within the budget of the government

220
00:10:37,321 --> 00:10:41,230
but also the area of the house is exactly the same,

221
00:10:41,230 --> 00:10:42,370
but much more comfortable.

222
00:10:42,370 --> 00:10:45,502
Many of the people want to stay here forever.

223
00:10:45,502 --> 00:10:48,064
I was very happy to hear that.

224
00:10:48,064 --> 00:10:52,001
Now I am working in New Zealand, Christchurch.

225
00:10:52,001 --> 00:10:55,848
About 20 days before the Japanese earthquake happened,

226
00:10:55,848 --> 00:10:57,353
also they had a big earthquake,

227
00:10:57,353 --> 00:10:59,914
and many Japanese students were also killed,

228
00:10:59,914 --> 00:11:02,233
and the most important cathedral of the city,

229
00:11:02,233 --> 00:11:05,004
the symbol of Christchurch, was totally destroyed.

230
00:11:05,004 --> 00:11:09,102
And I was asked to come to rebuild the temporary cathedral.

231
00:11:09,102 --> 00:11:11,389
So this is under construction.

232
00:11:11,389 --> 00:11:14,729
And I'd like to keep building monuments

233
00:11:14,729 --> 00:11:16,959
that are beloved by people.

234
00:11:16,959 --> 00:11:18,398
Thank you very much.

235
00:11:18,398 --> 00:11:20,334
(Applause)

236
00:11:20,334 --> 00:11:23,067
Thank you. (Applause)

237
00:11:23,067 --> 00:11:25,824
Thank you very much. (Applause)
