    I found a webpage that provides more detailed info. Highlights:
    http://god.tksc.nasda.go.jp/lr/top.html
    
    50-centimeter diameter, 86-kilogram  (smaller than EGP/Ajisai)
    GTO -- 36198 km apogee, 251 km perigee, 28.5 deg inclination
    24 "metal mirror plate(s)", 126 "laser retroreflector(s)"
    Mirrors: 85% albedo, Aluminum
      (20) - 10.5 x 9.4 x 1.0 cm / 5.3 kg
       (4) -  8.4 x 5.6 x 1.0 cm / 0.5 kg (quite a mass difference)
    Launch date 2001 August 25
    Lifetime "over a month" 
    
    Epoch 2001/8/25 04:39:35.00UT (Launch Window : 04:00-09:00) 
    Semi-Major Axis 24597.741880764 km 
    Eccentricity 0.730481992 
    Inclination 28.491633373 deg 
    Argument of Perigee 179.065695554 deg 
    Right Ascension of Ascending Node 69.870582954 deg 
    Mean Anomaly 7.117897857 deg 
    Cross Sectional Area 0.173 m2 
    Satellite Drag Coefficient : 2.5 
    Solar refrectivity coefficient : 1.5 
    
    Mission Objective: To evaluate the Initial trajectory determination of
    JAPANESE Rocket H2A using SLR.  SLR Mission Objectives:
      - To evaluate the Initial trajectory determination of JAPANESE Rocket
    H2A accuarately.
      - Verification of the SLR station performance. We use this as target for
    wide dynamic range of transmitting/receiving test up to geosynchronous
    orbit for optical communication and SLR.
      - Air drug [sic] model could be modified using SLR data. 
    
    This page appears to have a rough mission timeline:
