Construction going on directly in front of the hotel / on the side, begins around 9:30PM / 21:30 and goes until 0400 in the morning. Extremely loud scraping, banging, along with the construction backup beeping all night long. No idea what they are doing, but it was every single night. Also, the wifi will go out or down to 0.01MBPS download speed at random, so I wasn't able to get much work done either. The rooms are OK, I did not see any mold as other reviews stated, and the windows open which is usually great, except for the crazy weird construction / scraping / energy attacks. Staff were polite and professional and up to the standard of hotels in Japan, but the phone did not work at all to call front desk. None of the buttons worked. Overall this hotel could be good with a bit of attention to detail.
