'''Mount Osore''' (___R ''Osorezan'') is a temple and miniature wasteland in the middle of the Shimokita Peninsula in Aomori, Japan.
Understand
According to Japanese tradition, Mount Osore — literally "Dread Mountain" — is the '''gateway to Hell''', where souls pause on their way to the underworld. A barren volcanic wasteland of howling winds and bubbling sulphur pits, the origin of the legend is easy to understand.
Mount Osore is not an actual mountain, but the area is surrounded by a number of picturesque peaks.
When to go
The temple is only open to the public from May 1st to October 31st, before the harsh winter sets in. The whole area of interest is within the temple compound which closes early (probably at 7 PM) so make sure you arrive in time.
Get in
Most visitors arrive by bus from Mutsu. A rarely-used road (not served by public transport) also links to the Yagen Valley.
If you are driving, take Rte 279 or Rte 338 towards Mutsu. Follow the blue signs which will have "Osore-zan" written on them and will lead you straight to the site. Osore-zan is about a 2 hour drive from Aomori.
Another alternative is to '''hitchhike''' to the temple from Mutsu; locals should be able to point out the access road, which is marked by signs in only a few scattered places. During vacation periods, traffic to the temple is fairly heavy and finding a ride is not too difficult.
Admission is 500 yen for adults and 100 yen for children.
Get around
Your only option for getting around is on foot.

'''Bodaiji Temple''' (______, also referred to as ''Entsuji''), run by the Soto Zen sect, is built around a number of volcanic cauldrons (Jp. ''jigoku'', literally "hells"), bubbling in all sorts of unnatural shades from canary yellow to blood red. There are also many, many offerings to the souls of the dead scattered around the area, including tiny Jizo statues wearing bibs and piles of pebbles built (or so they say) by the souls of children who died before their parents. Entrance to the temple costs ¥500 (including a dip in the baths, see Do).
The small '''Sanzu River''' (_O_r____ ''sanzu no kawa'') is the Japanese equivalent of the river Styx. The river is crossed by a picturesque arched red bridge which souls have to cross to escape.
'''Lake Usoriyama''' (_F_]___R__), by the temple and the sink of the river, is a volcanic crater with (on a sunny day) an almost deceptively attractive-looking white sand beach... but the water, full of sulfuric runoff, is far too poisonous to sustain any life.
Do
Take a free dip in the holy (if somewhat stinky) waters in the bathhouses right after the temple entrance.
The rather somber '''Osorezan Taisai''' (___R____) festival is held between July 20 and 24. During the festival, traditional mediums known as ''itako'', all blind women, channel the spirits of dead people (''kuchiyose'') to relatives.
Buy, Eat & Drink
There are a number of small restaurants and souvenir shops outside the temple.
Sleep
The temple offers lodging for pilgrims (¥10000-15000 with meals), tel. 0175-22-3825. However, unless you like the pervasive smell of rotten eggs, you might wish to stay in Mutsu or Yagen instead.
Stay safe
Due to intense volcanic activity sulphur dioxide and other gases are abundant, so the entire area smells like '''rotten eggs'''. Soil near some of the cauldrons may not be stable, and the liquids inside are literally boiling. Heed the warning signs, do not cross the ropes, and head out if you start to get a headache or feel sick.
