Located in Hiroshima, which is remote from big cities, it is well-known widely as a sightseeing
spot of World Heritage Site. A mobile phone participatory sensing system in tourist subjective data
collection has been developed with Android smartphone. In order to analyze the subjective data, we use
the Growing Hierarchical SOM and our proposed variant methods. One is the control method of the
growing degree by pruning off the redundant branch of hierarchy. The other is the local reclassification
based on human intuitive in the Android interface tool. In this paper, we classified the subjective data by
interactive GHSOM and extracted knowledge related to Hiroshima sight seeing spot by C4.5.
