There are around 600 steps that you can climb to get to the main deck of Tokyo Tower. Those who've signed up for the TELL Tokyo Tower Climb, however, have already taken the most important step.

The Tokyo-based not-for-profit organization is holding its annual climb for the third year to mark World Suicide Prevention Day on Sept. 10 and raise awareness about mental health issues. The climb itself will take place at the tower on Sept. 8, bright and early at 7:30 a.m.

Last year's event raised more than ¥4 million, with proceeds going toward providing support to TELL's crisis chat service, which operates 24 hours a day and handled 8,825 calls in 2018. While initially focusing on the English-speaking community, TELL has, over the years, expanded its services to provide support services in multiple languages.
