Japan is a country of tradeoffs. Though there is an intentional paucity of public waste receptacles, there are plenty of free public restrooms, something that foreign tourists should note with appreciation. What they may not appreciate is the fact that most of the public facilities still feature squat-type toilets, which is certainly an irony since one of Japan's most famous gifts to the world is the all-service commode, or "washlet," which does practically everything but pull your drawers up.
We searched high and low for some kind of survey that revealed the portion of public toilets that are squat-type and couldn't find any, so our claim that most public toilets, whether they be in parks, train stations or just along a street, feature squat type facilities is mainly due to observation.
But it's obviously a situation that people are aware of. Chiba Prefecture recently announced that it set aside a supplemental budget in order to subsidize local governments and private entities who need to replace older Japanese style toilets under their management with Western style equipment before 2020, when Tokyo hosts the Olympics and it's assumed lots of foreign tourists will come to the metropolitan area.
