This is rare opportunity to stay at historical Nakagin Capsule Tower.
Designed by Kisho Kurokawa in 1972, Nakagin Capsule Tower is a rare built example of Japanese Metabolism, a movement that became emblematic of Japan's postwar cultural resurgence. The building was the world's first example of capsule architecture built for actual use.
You can not sleep over at Nakagin Capsule tower, but you can sleep at another apt which is just 2 min walk.
First, you will check in at the other apt.
And I will meet you to take you Nakagin room and give you tour and tell you the rule (for first time. And after that, you can visit Nakagin any time)
