NOBOROCK Shibuya grades, explained
ノボロック 渋谷店
NOBOROCK is a bouldering chain with eight gyms in Tokyo and nearby: Shinjuku, Asakusa, Takadanobaba, Shibuya, Ikebukuro, Machida, Mizonokuchi and Omiya. The Shibuya gym is a 170-tsubo (about 560 m²) basement gym 5 minutes from the south ticket gate of JR Shibuya Station. Its beginner wall is separate from the main wall, which has 80° to 150° angles, over 130 problems from 6級 to 3段+, and a monthly route set.
Bouldering grades
Problems use the Japanese kyu/dan scale: the main wall runs from 6級 to 3段 and up, and a climber reports 10級–7級 on the beginner wall. Grades are marked with coloured tape and tracked on a 'colour tape challenge' sheet, but the colour key is not published online. Font equivalents use the kyu/Font table on Japanese Wikipedia, not a gym conversion; climbers rate NOBOROCK's grades as soft.

NOBOROCK's gyms appear to share this grading, though NOBOROCK doesn't say so outright. All NOBOROCK gyms and grades
From climbers' descriptions and photos of the gym's grade boards. Gyms reset and regrade often, and grades vary between setters, so treat this as a guide and check the boards when you visit.
