[mountain climbing attention caused by Kumamoto earthquake]
In each mountain climbing road that we published below of Mount Aso origin, collapse and crack occurred under the influence of Kumamoto earthquake on April 16, 2016 and the next heavy rain, and route was cut apart, but we carried out safety measures such as installing sign and rope to promote attention in black spot and became able to climb a mountain about the following routes.
Traffic possible ⇒ east side route, clockwise route
Valley route of ⇒ hot water impossible of traffic, suigyoku route

<Takaoka, Mt. Naka-dake> (this time update)
There is no route which becomes during entrance regulation, and is passable now as volcanic activity of Aso Mt. Naka-dake is active.
On April 21, 2020 (Raiwa 2), we checked sensuibikon route. As there was influence by volcanic gas accompanied with volcanic activity activation of Aso Mt. Naka-dake, and the route could not find safety of mountain climbing route as a result of check in sensuibikon route because there was rock which could cause fall called popular name "egg rock", we judged with traffic impossibility (we do not recommend traffic as mountain climbing route). In addition, we cannot pass because it is in around crater regulation range accompanied with pulling up to volcanic alert levels 2 of Aso Mt. Naka-dake in sensuikyo ropeway trace route.
Passable route when regulation was canceled is as follows.
Sand Chisato route, Mt. Naka-dake ... large pan - Toho - Takaoka route, manners pine route, sensuikyo ropeway trace route
Please confirm regulation information of the crater in "Aso volcano crater regulation information" http://www.aso.ne.jp/~volcano/.
