1. This investigation was carried out as the beginning to make clear the connections between the soil micro-organism and the vegetation, richness and barreness of soils at the sand dune.2. All samples were collected at ten parts at various fixed distances from the shore-line, in April to June.3. The species and number of fungi in the soils at every part are varied according to cover plants, season and movement of sand.4. The most common fungi in sand dune soil were Penicillium and Aspergillus.5. Penicillium was found in the soils of every part in all the three months, but Aspergillus was found for the all months at all parts except the two, where it was not found at all.6. Mucor was also the common genus found in the sand dune soil next to Penicillium and Aspergillus. This is relatively abundant in fertile and moderately moistened plantation soils (Pinus Thunbergii PARL., Robina Pseudacacia L.), though a small number of it was discovered in the barren soil near the shoreline.7. Fusarium was found only in June; this fungus was numerous in plantation soils as those of Robina Pseudacacia L., though a few was found in the soils of wild grasses (Carex Macrocephala WILLD.).8. Epicoccum was found very rarely plantation soils (Populus L.) in April, and Zygorhynchus was found to some extent in June at the some place, the farthest part from the shore-line.9. Cladosporium, Rhizops, Alternaria were found very rarely in barren and fertile soils.10. Besides, I found an unidentified fungs, so I am now studying what sort of a fungus it is.
