Masayuki Kubo, an 80-year-old retired FAA construction engineer, vanished from his Honolulu condominium on Kapiolani Boulevard after leaving for a routine walk. He often walked to Kakaako Waterfront Park to watch fishermen and sometimes took multiple strolls a day. On the morning he disappeared he wore a white t-shirt, blue jeans, and white sneakers and carried his state ID, a bus pass, and a small amount of cash.

Kubo had been diagnosed with Alzheimer’s disease and had two recent episodes of disorientation while walking — one requiring a neighbor’s help after a fall and another when a neighbor brought him home from Kapiolani Park. The morning after he went missing a security guard at the Ohana Maile Sky Court Hotel reported a man identifying himself as Masa who was later recognized from a missing-person flyer; the guard said he put the man into a taxicab to the Waikiki Beach Marriott Resort, but taxi inquiries produced no leads. A separate unconfirmed sighting described a tired, dirty man matching his description in a downtown Korean restaurant.

Family and neighbors circulated flyers, searched the area, and the police checked bus lines, shelters, and the airport without success. The absence of confirmed follow-up sightings and the fact he was off his medication left the family anxious. If anyone saw Masayuki Kubo on or after the morning he disappeared, or has information about those possible sightings, please come forward.
