To help Fukushima recover, of course. Wirtschaft über alles. Above well-being of children.
(That's part of what 20-plus years of economic "malaise" does to a country.)
From NHK Tokyo Metropolitan Edition (link won't last, emphasis is mine; 9/4/2012):
[Fukushima officials] luring school trips to Fukushima Prefecture
On September 4, officials from the Fukushima prefectural government dropped by at the conference of the principals of metropolitan (public) high schools (in Tokyo) to promote Fukushima as the destination for the school trips. The number of students who visit Fukushima Prefecture on school trips has dropped off significantly due to the March 11, 2011 earthquake and the nuclear accident.
About 700,000 children used to visit Fukushima Prefecture every year for school trips and training camps. However, last year after the disaster, 90% of these trips were canceled. It hasn't recovered to pre-disaster level yet this year.
So, the Fukushima prefectural government has started an initiative to attract school trips mainly by schools in Kanto Region. On September 4, the officials in charge participated in the conference of principals from metropolitan high schools, which was held in Bunkyo-ku, Tokyo.
Mr. Haruo Hoshi, head of the Tourism and Exchange Bureau of Fukushima Prefecture, told the principals, "Except for the areas damaged by the tsunami and the nuclear accident, things are getting back to normal. I would like you to tell the parents [of your students] that Fukushima is safe."
Then, other officials explained that visitors from Tokyo had dropped off dramatically except for training camps by college students, and the prospect was dire, but radiation levels were such that they wouldn't affect health except for part of Fukushima close to [Fukushima I] Nuclear Power Plant.
Mr. Hoshi said, "Fukushima has a lot of cultural and historical attractions, and we offer rich programs for school trips. We will do our best in attracting [the schools] and bring the number of visitors to the pre-disaster level."
Radiation levels are such that they won't affect health, meaning they are low except in the immediate neighborhood of Fukushima I Nuke Plant. Only in the minds of government officials in Fukushima.
To these officials from Fukushima City (that's where the prefectural government office is located), radiation levels in Fukushima City and in Nakadori (middle third) of Fukushima are not high. 1 microsievert/hour at 1 meter off the ground? Not a problem. Why? Because these officials live there and they say so.
What is this obsession of sending or bringing young people and children to Fukushima (of all places)? Remember the misguided attempt to send elementary school children to Date City to give cheer to the people there? The LDP city assemblyman in a city in Osaka who was going to co-sponsor the event was extremely indignant that he was roundly criticized for proposing the trip, which he eventually canceled. He clearly did not understand why people were upset with his project of good intention.
The school principals, being more of administrators than educators, will duly follow official recommendations.
