From Kokkai-gijidomae bus stop on the Toei Bus "橋(Hashi) 63" Route bound for Otakibashi-Shako to the NDL (Verbal Descriptions of Walking Directions)

1. With your back to the bus, proceed forward about 3.5 meters in the 12 o'clock direction until you reach braille blocks running left to right.
2. At the braille blocks, turn in the 3 o'clock direction and walk about 50 meters until you reach an intersection branching in the 2 and 10 o'clock directions.
3. At the intersection, turn in the 2 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.)
4. 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.)
5. 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.
6. At the intersection, turn in the 4 o'clock direction and walk about 1 meter until you reach a 10 o'clock turn.
7. 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.)
8. At the intersection, turn in the 9 o'clock direction and walk about 4 meters until you reach a turn toward 3 o'clock.
9. 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.

14. At the turn of the braille blocks, turn in the 9 o'clock direction and walk about 2 meters until you reach the T-shaped braille blocks.
