He entered inside the Big Brother house in Vietnam on Day 2, together with Jinri and JK. However, they were chained and blindfolded. Their fellow celebrity housemates must find the right keys among the 77 keys scattered inside the house and must unlock them all within 30 minutes. They were eventually unlocked.
On Day 4, their first nominations occurred and Hideo was put up for eviction. The next day, the first eviction of the season happened. The nominees must eat two out of three exotic Vietnamese dishes for the Ligtask. The housemate who finished the longest will be evicted. Hideo finished the challenge in 15 minutes, which was the longest time among the nominees. Since he got the longest amount of time, he was supposed to get evicted. However, Chacha expressed her decision to voluntarily exit the house and gave up her spot for Hideo instead.

They entered the house on Day 17. The housemates then competed in the Big Jump Competition. Hideo failed to advanced to the second round. Jinrieventually won the Lucky Star slot. The housemates who failed to get the Lucky Star slot faced the eviction where the public would vote for the housemate who will get the second slot. Nikko and McCoy got the second slot. Hideo and the rest of the housemates got evicted on the same night leaving the two Lucky Stars inside the house. He placed 7th in the Celebrity Edition of the series and landed on 29th place overall.
