Orix Corp.'s purchase of 70 Kampo no Yado hotels from Japan Post Holdings Co. for the fire sale price of ¥10.9 billion has been making headlines for the past month and drawing the scorn of internal affairs minister Kunio Hatoyama.

The incident seems to be expanding day by day, with Hatoyama threatening to inspect Japan Post Holdings for failing to disclose the details of the offer.

Japan Post Holdings President Yoshifumi Nishikawa said he would freeze the deal and set up a panel this month to review it, but despite the monthlong outcry little is known about Kampo no Yado.
