Japanese PM Nowhere To Be Seen

The Second Nuclear Security Summit was over at Seoul, South Korea, under the growing shadow of the North Korean threat to launch what it calls a satellite. But my attention was drawn to the behaviour, or the non-behaviour, of Japan's Prime Minister, Mr.Noda Yoshihiko.
He left Tokyo's Haneda Airport at 7.19 pm on 26th for Seoul's Kimpo Airport. By the time he checked in the Lotte Hotel it must have been around 10 pm, too late for whatever may have been going on as a part of the Summit. It was in the morning, the next day 27th, that he met the host of the Summit, the South Korean President.
Did the other heads of the states/governments behave in a similar way? Far from it. In the afternoon of 26th, for example, Chairman Hu and President Obama had a 90-minute conference. There was also a meeting between the Russian and South Korean Presidents, and so on. Mr.Obama had a conference with the South Korean host even on the previous day, 25th.
The 27th was the main day. But it seems Mr.Noda had invited, or had been invited by, any one for a person-to-person talk. It is true he had a talk with as many as a dozen heads of the states/governments. But they were all between the sessions, in the corridors(of power?), and for only several minutes, both sides standing, hardly worth to be called a meeting. Mr.Noda's view became known only by a formal speech he read out at the main conference.
He arrived back at Haneda at 5.04 pm on that same day. In order to do so he must have left the hotel at 2.30 latest(there is no time difference). Taking into account the group photograph, the working lunch, and the press conference at the hotel, all in the published diary, it is difficult to imagine that he could have any meaningful talk with any one present at the Summit.
Thus ended Mr.Noda's two-day visit to Korea. True, on both days he had a busy schedule at home. But that is a different matter. There were as many as 53 heads of states/governments at the Summit. If Mr.Noda did not find it necessary to talk to them, even at the cost of part of his political programme at home, it is, to say the least, surprising.
