Mouko no zenbou : nazo no hikyou
Nazo no hikyou mouko no zenbou
Hikyou ni saku hana
Kasen ni chiru
Kasen o koshite : manshuu shanhai jiken bidanshuu
Chousen no kasen

秘境の秋
Fukushimaken kasen no kenkyuu
Sekai no shinpikyou arabiya juudanki
Sekai no shinpikyou arabiya juudanki
Etchuu no himitsukyou kurobesan tanken

奥会津の秘境
Hichuu no hi
Kasenjou no oushuu : sekai kiki no kaibou
Kiso no shinpikyou : fu koushuu minobusan
Fuuzoku shiki kasen niwa no yuki
Sorenpou no kasen to suiro shisetsu
Hikari faibā bunpu senshingu no houshasen kankyou he no tekiyou
大自然の秘境を探る噴火口登山道路
