   (Note: There are no braille blocks between those two automatic doors.)
2. Exit the automatic doors and you will be outside. Proceed forward about 4 meters in the 12 o'clock direction until you reach a turn toward 3 o'clock.
3. At the turn of the braille blocks, turn in the 3 o'clock direction and walk about 23 meters until you reach another 9 o'clock turn.
   (Note: There is a ceiling after about 21 meters in the 3 o'clock direction.)

   (Note: There are two intersections heading in the 3 o'clock direction along the way.)

   (Note: The ceiling continues almost until you reach the stairs. About 2 meters after the ceiling disappears, you will reach the stairs. On the way, in about 10 meters, there is an intersection heading in the 9 o'clock direction.)
7. Proceed up the stairs 14 steps until you reach the T-shaped braille blocks. Continue forward about 4 meters in the 12 o'clock direction until you reach more T-shaped braille blocks. The gate of the National Diet Library is located here. Braille blocks are discontinued about 1 meter before and after the gate.

9. At the turn of the braille blocks, turn in the 3 o'clock direction and walk about 5 meters until you reach T-shaped braille blocks.
10. At the T-shaped braille blocks, turn in the 9 o'clock direction and walk about 3 meters until you reach more T-shaped braille blocks.
11. At the T-shaped braille blocks, turn in the 3 o'clock direction and walk forward down a gentle downhill slope for about 40 meters until you reach an intersection branching in the 12 and 3 o'clock directions.
    (Note: On the way, in about 20 meters, there is an intersection heading in the 9 o'clock direction.)
    (Caution: If you reach the T-shaped braille blocks after passing the intersection heading in the 12 o'clock direction, you have traveled too far. Do not proceed beyond this point as it is an entrance/exit for cars. At the T-shaped braille blocks, turn in the 3 o'clock direction and you will come to a street light pole and a signboard.)

    (Note: The traffic signal of the crosswalk is acoustic and sounds like the call of a cuckoo when it is safe to cross.)
18. Braille blocks are laid out in the center of the crosswalk. Follow those braille blocks for about 13 meters until you reach a sidewalk.
19. Proceed forward about 5 meters in the 12 o'clock direction until you reach an intersection branching in the 4 and 10 o'clock directions.
20. At the intersection, turn in the 10 o'clock direction and walk about 10 meters until you reach a 2 o'clock turn.
    (Note: On the way, in about 4 meters, there is an intersection heading in the 10 o'clock direction to a crosswalk which you do not want to use.)
