One of the best places to have a taste of this awesome delicacy is Okonomimura and around Hiroshima station. Asides the local tastes and dishes, there are other Japanese and international cuisines to try out. There are good selections of spots that serve the tourists who visit the island.
Getting Around
Hiroshima currently has Japan's largest tram network with eight tram lines connecting Hiroshima Station with most of the city's attractions.

Language
Japanese alongside English are the official languages in Japan but there are a lot of dialets. The Hiroshima Ben (Hiroshima Dialect) is one of the most recognizable Japanese dialects.
Money
The Japanese yen (JPY) is the official currency of Japan. It is the third most traded currency in the foreign exchange market after the United States dollar and the euro. Coins in circulation are are 1, 5, 10, 50, 100 and 500 yen. The 5 and 50 yen coins have a hole in the middle. Banknotes are denominations of 1, 000, 5, 000 and 10, 000. Although the 2, 000 yen notes are in existence, they are rarely seen in circulation. Many Japanese ATMs don’t accept foreign-issued cards and credits cards are not universally accepted in Japan.
Negatives
Hiroshima is much safer than any large Western city. As with most places in Japan, petty theft is virtually non-existent. Nagarekawa, the nightlife district, does have its share of prostitutes, sex clubs, and rip-off hostess bars, but to no greater extent than Tokyo or Osaka. There have been a few surprise police raids on bars that offer dancing after 1AM, in accordance with a semi-obscure local law about public immorality that Hiroshima occasionally feels compelled to enforce — probably in order to catch people who are in the country illegally.
Japanese citizens are generally allowed to leave right away, but foreigners have been made to stand in line to have their paperwork checked. If you find yourself in one of these situations, just stay calm, show the police your passport and you'll eventually be allowed to leave without any trouble. - Wikitravel
