The museum's mobile exhibition guide page warns that as of September 2026 the permanent galleries are under renovation and new guide content will be prepared after completion. It still describes QR-based explanations in Korean, English, Japanese, Simplified and Traditional Chinese, plus HSBJ Wi-Fi, but those descriptions do not guarantee current content for the rebuilt galleries. Visitors scan exhibit QR codes with their phones; earphones are not lent. Ask the desk on 02-2152-5800 about currently usable interpretation and printed guides.
