timelesz members Hara Yoshitaka and Shinozuka Daiki are taking on an unusual challenge on Japanese television. The duo will appear on TBS's "Chikyū Marugoto Dai Jikken: Nature Teacher" airing June 2nd at 11:56 PM, where they'll co-host alongside comedy duo Chocolate Planet.

The show follows a format where the hosts learn from nature specialists and attempt risky experiments. This episode's experiment: can an industrial-grade water filter remove the heat from an extremely spicy sauce?

The team will be testing their skills using "After Death Jokolia," a hot sauce made from bhut jolokia and habanero peppers—the bhut jolokia has been recognized by Guinness World Records as the world's hottest chili pepper. After getting a taste of the sauce and experiencing its intense heat firsthand, the hosts will work with Karifana Manufacturing's representative to understand water filtration technology before attempting to filter out the sauce's capsaicin.

The episode represents one of several recent TV appearances for timelesz members. The group has been keeping busy with various entertainment projects, from drama roles to talk show appearances. These variety show appearances continue timelesz's presence across Japanese entertainment beyond their music activities.

For fans of the members or anyone curious about whether modern filtration can actually neutralize extreme spice, the episode airs tonight on TBS (excluding some regions).
