Route Notes	Hiroshi, Japanese Numbur summiter - 24 Dec 83 1963 Numbur Hitachi believes 1963 expedition was successful. Their account of a final push gives "reasonable" time and description of summit and rock just below it is entirely accurate. Numata (leader) - 7 June 63 Chiba University Expedition 4 mountain climbers reached KTM June 17th. 2nd scientific June 22nd. 1 member went to Calcutta Thursday, leader Yoda Sunday and 4 finally on 9th. Leader and Yoda will reach Japan end of July (via Bangkok for 2 weeks botanical survey in Thailand). Sherpa is instructor at HM Institute in Darjeeling - Mingma Tsering. Matsuo is photography engineer working for photography Co that makes color film. Oriental Photographic Industry Co in Tokyo on engineering staff; this 1st time in March. Plans to come again to climb Gaurishankar in 1965. Climbing last 2 days very difficult but all in good health. More difficult than expected. No one even attempted climb Numbur before because of very hard blue ice between C4 and C5 which have more of in Japan. 2 botanists with expedition studied material in East Nepal especially Junbesi and Jiri - vegetation very similar to Japan. Collected many plant specimens, insects, etc. Report later after study date knew this from fewer rept but surprised at its extent very similar especially in temperate zone. 1st study ecologically and socialogically in east Nepal done by this group. Himalayan Expedition of the Chiba University (to Rolwaling Himal 1963) "Expedition aims at bio-ecological survey on the vegetation and animals, the human-ecological survey on surroundings and life of the alpine inhabitants and if possible, climbing of mountain Numbur (6954m) which has no record of climbing."
