Route Notes Summit date: 24 May by Ogasawara, Pemba Nurbu, Pemba Rita and Mingma Gyalje at 10:30 am (NST). Ogasawara, Pemba Nuru, Pemba Rita and Mingma Gyalje left C3 at 9:30 pm on 23rd May. They were together with Peter Adolfsson and his Sherpas. It was snowing and there was a bit of a wait at the steps. Adolfsson reached the summit before Ogasawara, who got there at 10:30 am, but Adolfsson met him when he was on his way down. Even though Hiroshi seemed exhausted he was doing Ok. He said he was tired, but Ok. Pemba Nurbu told Adolfsson later that at one point Ogasawara grabbed his heart on the summit and said there was a slight pain. However, he got down to the 3rd Step Ok, but when he reached the 2nd Step he had to be short-roped and helped down. His three Sherpas dragged him down. Pemba Rita was running up and down between C3 and 8400m to get some water and tea for Hiroshi. When Hiroshi and Pemba Nurbu got to about 8400m, Hiroshi sat down and collapsed and died at about 1:30 am on 25th day. Nobody knows what Hiroshi died of. Pemba Nurbu arrived at C3 at about 3 am. He was very tired and very shaken.
