Arti was quite knowledgeable. The tour was fair, with the exception of the WW II museum. Paying for taxis and his entrance fee to the Guest House, which he indicated was usual and customary, however, our experience with TBL is that most of the tourist attractions provide free entrance to legal tour guides. The use of taxis was a necessary evil during the day due to the extreme heat and short times between activities, but taxis in Tokyo are not inexpensive and at times the train could have been an option.
