You have to go through a metal detector and write your name, the guards were shocked that I wrote in kanji and katakana! It is pretty fun shocking people with the fact that I can do Japanese!
I took a free tour with 3 other Japanese tourists, which was pretty cool. Surprisingly I understood quite a bit of what the tour guide said:
- The carpet costs 30000Y a square meter.
- Under the carpet, the marble floor turns to concrete!
- They hold (or used to hold) parties in the upper floors of the tower thing (pictured- thanks to Wikipedia).
- There are a couple doors to the Emperor's room, the door with marble columns is for the Emperor only.
- The "Central Staircase" is only used when the Emperor comes
- Pairs of stenographers switch off every 5 minutes at the sound of a bell
- Mail chutes installed in the 1930s (?) are still used now
- In the area for reporters, there are pneumatic tubes (like the drive-through-bank-teller-windows) that were/are used to send notes and current information to the newspaper companies
I took some pictures on my cell phone (forgot my camera again!). After I buy a "micro-SD" card I can post them!
