This part of the city was used to transport and store lumber via its extensive network of canals; this is seen as recently as the mid-1980s. By 1984/87 the complex was completed, and lumber is no longer visible in the canal.
Lumber was stored in kiba, which means ‘timber basin’ 貯木場, a variation of ‘lumberyard’ 貯木. For more information see: Odaiba, then & now: a visual history
