From Tokyo Metro Kokkai-gijidomae Station, Exit 2 Elevator to the Ground Level to the NDL (Verbal Descriptions of Walking Directions)

1. First, take the elevator to the ground level that leads to Exit 2 of Kokkai-gijidomae Station. Exit 2 is at the street level. With your back to the elevator at Exit 2, proceed forward about 1.5 meters in the 12 o'clock direction until you reach a 9 o'clock turn.
2. At the turn of the braille blocks, turn in the 9 o'clock direction and walk about 4 meters until you reach T-shaped braille blocks. Beyond this point, you will come to a sidewalk.
3. Continue forward about 1 meter in the 12 o'clock direction until you reach braille blocks running left to right. Braille blocks are discontinued at this point.
4. At the braille blocks, turn in the 3 o'clock direction and walk forward up a gentle uphill slope for about 70 meters along linear braille blocks until you reach dotted braille blocks. Proceed forward along the dotted braille blocks for about 10 meters.
   (Note: Exit 1 of Kokkai-gijidomae Station is on your right while you are walking along the dotted braille blocks. There are stairs and an escalator at Exit 1. The escalator goes up and down in different directions depending on the time of day.)
5. After passing the dotted braille blocks, continue forward about 10 meters until you reach a 2 o'clock turn.
6. At the turn of the braille blocks, turn in the 2 o'clock direction and walk about 10 meters until you reach dotted braille blocks.
   (Note: On the way, in about 6 meters, there is an intersection heading in the 7 o'clock direction to a crosswalk which you do not want to use.)
7. After passing the dotted braille blocks, braille blocks will stop for about 7 meters.
   (Note: On your right side will be the gate of the National Diet Building.)
   (Caution: After the braille blocks end, there is a step that drops about 3 cm. There is a gentle downhill incline towards the road on your left from the gate on your right.)
8. Proceed forward about 7 meters in the 12 o'clock direction until you reach another dotted braille blocks.
   (Caution: There is a step that goes up about 3 cm where the dotted braille blocks restart.)
9. At the dotted braille blocks, proceed forward about 9 meters in the 12 o'clock direction until you reach an intersection branching in the 10 and 2 o'clock directions.
10. At the intersection, turn in the 2 o'clock direction and walk about 380 meters until you reach another intersection branching in the 2 and 9 o'clock directions.
    (Note: For 380 meters, there is no crosswalk in the direction you want. On your right side is the property of the National Diet Building. You will find intersections heading in the 3 o'clock direction to its gate while walking. On your left side is a row of trees, with a road on the other side. You will also find intersections heading in the 9 o'clock direction to parking spaces and crosswalks. There are nine intersections indicated by braille blocks in the 380 meters.)
11. At the intersection, turn in the 2 o'clock direction and walk about 8 meters until you reach another intersection branching in the 10 and 2 o'clock directions.
12. At the intersection, turn in the 10 o'clock direction and walk about 3 meters until you reach a crosswalk with traffic signals. The name of the crossroads is Kokkai Toshokan Mae ('In front of the National Diet Library').
    (Note: The traffic signal of the crosswalk is acoustic and sounds like baby chicks chirping when it is safe to cross.)
13. Proceed forward through the crosswalk for about 23 meters until you reach a sidewalk.
    (Caution: Braille blocks are not laid out in the center of the crosswalk. On the way, in 10 to 12 meters, there is the median strip. There is a step that goes up about 3 cm when entering the median, and a step that drops about 3 cm when exiting. There are curbstones on both sides, and the distance between them is about 3 meters.)
14. When you reach the sidewalk, proceed forward along braille blocks about 4 meters in the 12 o'clock direction until you reach an intersection branching in the 4 and 10 o'clock directions.
15. At the intersection, turn in the 4 o'clock direction and walk about 1 meter until you reach a 10 o'clock turn.
16. At the turn of the braille blocks, turn in the 10 o'clock direction and walk about 65 meters until you reach an intersection branching in the 12 and 9 o'clock directions.
    (Note: On the way, in about 35 meters, there is an intersection heading in the 9 o'clock direction to braille signage. Turn in the 9 o'clock direction and walk about 4 meters until you reach the braille signage.)
    (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 9 o'clock direction and you will come to a street light pole.)
17. At the intersection, turn in the 9 o'clock direction and walk about 4 meters until you reach a turn toward 3 o'clock.
18. At the turn of the braille blocks, turn in the 3 o'clock direction and walk about 25 meters until you reach another 3 o'clock turn.
    (Note: On the way, in about 10 meters, there is an intersection branching in the 9 o'clock direction that leads to the South Entrance of the NDL. The South Entrance is not the visitors' entrance, but you can use it if you need assistance. The directions in that case are as follows.
    At the intersection, turn in the 9 o'clock direction and walk about 13 meters until you reach a 3 o'clock turn. Turn in the 3 o'clock direction and walk about 3 meters until you reach a 9 o'clock turn. Turn in the 9 o'clock direction and walk about 6 meters until you reach the automatic doors. Braille blocks are discontinued at this point.
    Enter through the automatic doors and proceed forward for 3 meters until you reach the second set of automatic doors. There are staff near the automatic doors at the entrance to help you with your requirements.)

24. Proceed forward about 1 meter in the 12 o'clock direction until you reach T-shaped braille blocks. Continue forward about 4 meters in the 12 o'clock direction until you reach stairs going down with a handrail. The handrail is about 1 meter on your right if you have walked along the braille blocks.
25. Proceed down the stairs 14 steps until you reach the T-shaped braille blocks. Continue forward along braille blocks about 60 meters in the 12 o'clock direction until you reach the automatic doors.
    (Note: With your back to the stairs, proceed forward about 2 meters and there is a ceiling. The ceiling continues until you reach the automatic doors. On the way, in about 50 meters, there is an intersection heading in the 3 o'clock direction.)
26. Braille blocks are discontinued about 1 meter before and after the automatic doors. Enter through the automatic doors and you will be inside the building. Proceed forward about 15 meters until you reach the second set of automatic doors. This second set of automatic doors leads to the entrance of the Annex.
    (Note: There are two intersections along the way. In about 2 meters, there is an intersection heading in the 9 o'clock direction. Turn in the 9 o'clock direction and walk about 3 meters until you reach braille signage. At the first branching, proceed forward about 8 meters in the 12 o'clock direction until you reach another intersection heading in the 9 o'clock direction. When you turn in the 9 o'clock direction and walk about 3 meters, you will come to the automatic doors which are the entrance of the Main Building. If you already have your registered-user card, you can enter through here.)
27. At the automatic doors leading to the entrance of the Annex, braille blocks are discontinued about 1 meter before and after the automatic doors.
    Exit the automatic doors and you will be outside. Proceed forward along the braille blocks about 8 meters in the 12 o'clock direction until you reach a 3 o'clock turn.
28. At the turn of the braille blocks, turn in the 3 o'clock direction and walk about 23 meters until you reach a 9 o'clock turn.
