     ==================================================================

The 5th International Workshop on Neutrino Oscillations and their Origin 
(NOON2004) will be held at Tokyo, Japan, from February 11th to February 
15th of 2004. This is the fifth workshop of this series.

The neutrino oscillations discovered in atmospheric and solar neutrinos, 
are now confirmed by the terrestrial oscillation experiments by using 
man-made neutrinos by a high energy accelerator and nuclear reactors.  
It is now important to make precise studies on neutrino mixing matrix 
including a search for positive effects of as yet undiscovered theta_13, 
and on sub-dominant effects due to neutrino properties which may be 
hidden in the current experimental accuracy. The terrestrial experiments, 
as well as the precise studies on atmospheric solar neutrinos may lead us 
to the physics beyond the standard scenario of neutrino oscillations.

This workshop is therefore organized to discuss the recent progress 
in neutrino oscillation physics and future directions by theorists and 
experimentalists together. Astrophysical implications on neutrino masses 
and oscillations are also important subjects. We also include the 
related subjects like search for neutrino masses by double beta decays 
or by direct methods which will provide quantitatively different 
information than the oscillation phenomena. We extend the subject 
to include the studies on dark matter.

As a 5th workshop, we will discuss following subjects: 
1) Current status solar neutrino experiments and road map towards the future
2) Atmospheric neutrino results and future
3) Current status of accelerator neutrino experiments and future
4) Status of the theoretical study of neutrino mixing and mass 
5) Future prospects of neutrino oscillations study
6) Neutrino masses in cosmology 
7) mu->e-gamma and lepton flavor violation 
8) Proton decays, GUT, leptogenesis
9) Astrophysical neutrinos, neutrinos from supernovae
10) Study on double beta decay
11) Dark matter search 
and other related subjects.
